How much faster is the 6.2 than the 5.3?! 

Guys i love these trucks with the 5.3, not degrading them at all. Just a fun comparison video between the two engines!

I have a Denali 6.2 and my friend with the 5.3 was extremely jealous when I stomped the accelerator. But I am jealous of him at the gas pump.

I went from a 5.3 suburban to a 6.2 Escalade, it’s a huge difference. That 6.2 throws you back into the seat nicely 😂

I wished Chevy would start offering the trail boss with 6.2 supercharged from the factory with about 750 horsepower.

One of the BEST side-by-side comparisons I've watched on RU-vid, bar none! You've given me some great info to consider as I decide on the engine for my next Z71 Tahoe/Suburban.

In a PERFECT world I would like to have gotten the 6.2 but, I'm honestly happy with my 5.3... and you're right the10 spd makes a big difference. my 16 had the 8sps.

we need more of these again!! clearly people loved it man

These trucks are fast for being as big and heavy as they are wow I'm impressed

I have been very fortunate with GM! My 04 z71 with the 5.3 is still running like a top. Original everything except for plugs, wires and coil packs and runs like a scalded dog. Also very fortunate with my 15’ Denali with the 5.3. I have 6 inches of lift w/ 35’s and 26’s and can absolutely roast them down when I turn the stabilitrack off and it’s stock besides putting .410 gears front and rear. I also love the 6.2 but the 5.3 to me is one of the most well built engines/blocks ever produced

I agree the 10 speed is the biggest help to the 5.3L. I think it still has more in it with a gear change

Absolutely love my 6.2 use it to tow a 33' travel trailer does phenomenal

I love the smirk! You’re the right guy for the job. I have the 3 0 diesel. The only reason I didn’t get the 6.2 is the high test thing.

GREAT video...nicely done. My last two GM trucks had the 5.3L. My new truck (2021 GMC Sierra AT4) has the 6.2L. BIG difference. It also has a CAI, Borla muffler (flapper delete), Pulsar LT, and stock wheels (with one size taller Bridgestone Revo 3 A/T tires). No added weight with the tires. I call my current AT4 "a Corvette with four wheel drive". I didn't buy it for fuel mileage, or being in the slow lane. 91 octane is good. 93 octane is hard to find here in Oklahoma...but, it is def better. Thanks for doing an excellent real world video comparo. The 6.2L (to me) is the way to go and brings a smile to my face every time I wanna drive like Dale Earnhardt Sr.

In my 5.3 I definitely get a better and faster launch from just stepping on it rather than holding the brake.

that baby seat was weighing down that 5.3! Good video man! i have owned both and i love the 6.2 for towing!!

I have a 19 6.2 high country with 22inch rims. I had a 17 5.3 and I can feel the difference. Purchased the truck used but the drivetrain (motor, camshaft) had been replaced. Engines brand new lol I’m basically breaking it in right now. I’m happy with the vehicle

I had new 5.3L Silverados in 2008, 2012, and 2016. I bought a new 2019 with a 6.2L. The 6.2L get better mileage than the 3 previous trucks. The required 93 octane for the 6.2 costs 20% more, but it gets about 10% better MPG than the 5.3's. Probably due to the 10 speed transmission.

Love my 6.2 it’s daily driver pulling a trailer everyday all day for work ! Awesome

Great comparison video. Preciate it.

I had a 2017 Silverado crew cab 4x4 LTZ 6spd auto with the 5.3. It was good. But it always felt like it needed more. I put an cold air intake on, tune & a exhaust system. Better, but still seemed a little lacking.... Now I have another 2017 Silverado crew cab 4x4 LTZ with the 8spd auto & the 6.2l. Much much better overall. It is noticeably faster but surprisingly it gets slightly better fuel economy than the 5.3. I'm guessing the 8 vs 6spd has to help, but it is just a way better experience now. Imo it is a very worthwhile option if your in the market.

Great review, I have an ‘18 5.3 6 speed that’s just my luxury daily driver. But my son’s’19 5.3 8 speed is a world different. Smoother, faster, quicker & 25 mpg driving across country!

6.2 tows a lot better and gets better milage than the 5.3 while towing. Definitely less stressed and lower rpm while towing.

Loving the daily uploads!!

Great video bud I don't own either but I was curious keep up the great work

I love this dude, drag racing with the car seat in the back. Lmao. Love the video.

You did a great job comparing the two..not hating on your truck but it looks new again with the factory wheels on it..love the bull dog look with factory wheels and little bigger tires all within the confines of the wheel wells..I love wide wheels and big tires but late model trucks have wider tracks than older trucks and to me they look right just adding bigger tires and leveling them, they just look newer longer

Thanks for the video! It was very interesting!

Great video! Nice trucks as well! The white looks like it has the Carolina Squat happening with the lifted front end.

Max trailer tow package on the 5.3 changes the rear axle ratio.. Think it makes a substantial difference having the 3.42s

Great comparison video. Straight to the chase and informative. Would LOVE to see a similar idea but comparing your 6.2 to a newer 5.0 f150 or 5.7 ram 1500

I appreciate your vids. I got the pulsar because of YOUR vid. I have the pulsar intake also because of YOUR vids. I appreciate your knowledge and experience, thank you. I have the 6.2 custom 2022 trail boss...I LOVE IT

Nice! Excellent job on the comparison. 6.2 is a beast.

well said. I love my 21 tb with the 5.3 and ten speed. Tows great. exhaust, intake and pedal commander do help ;)

I have a 2020 sierra 5.3 x31 elevation zero problems! gas mileage is awesome. I have 22k miles on it. used regular gas from the beginning. I have never felt my truck is underpowered. the 8 speed is awesome zero problems. happy i went with the 5.3.

Two days ago bought the 2022 Silverado RST 6.2L verses the 5.3L. I drove it about 200 miles home, nice smooth ride. Happy with the 6.2

Great vid man love them!!, but also question regarding these trucks isn’t it not safe to drive these on 4x4 unless you are in the condition to not to launch em ya know?

Dude! This is such a great video! I've debated myself on the merits of the 6.2 versus the 5.3 . Wow, this is very informative. 6 2 is the way to go if you want performance, and, if you can afford it, is the better choice. It performs better, it sounds better, and has a much more visceral experience while going up through the gears. And a 13.86 is an awesome quarter mile time for a truck! Very competitive. Kudos to you for this video. And kudos to Chevrolet for still offering a large displacement V8. And for raising the top speed governor on these trucks to 112 mph on 2021's and after! Yeow!

Both are great engines and have plenty of aftermarket support

Love your channel and videos Chase

Can we just appreciate the Chevy Silverado line for a moment. Great video

Totally agree. The 5.3 is a good solid engine (but do frequent oil changes, don't go below 30% oil life). That being said, I got my 2019 AT4 with the 6.2 because... Just because. It's badass!

My 2019 5.3 is about all the tires can handle and personally I bought it for comfortable ROAD TRIPS

That 6.2+exhaust just sounds great

Just bought the 6.2 LTZ. Loving it power is insane

I might be the only one saying this but I MUCH prefer the look of your truck with the lightweight wheels and tires. It probably performs better in every conceivable scenario with the smaller tires as well.

My 5.3 Silverado dosnt stand a Chace against my 6.2 Yukon Denali, the difference is night and day. Once again great video man!

I put the L92/Vortec 6200 in my 05 Yukon XL SLT 2 wheel drive and i love it!!

Good video, real world numbers rather than something subjective is refreshing 👌🏻

I’ve had two 5.3 trucks and now a 6.2..huge difference. But still like the 5.3...it’s a solid engine.

I engined swapped my 15 Chevy from a 5.3 to a 6.2 with stage 3 cams(including pushrods lifters springs and valves)long tube headers,3600 torque converter,and dyno tuned made 610 hp and 451whp it sounds like and launches like a beast

I've owned both. Had a 2014 ltz z71 that I got before the 6.2 was available in that model. Was happy with it. Did a cat back exhaust and cai with tuner. Was a fun truck. I finally traded it in. Picked up a 2021 Sierra Denali with the 6.2. Drove straight from the lot to the exhaust shop. Had it for about 6 months and it's a huge difference in power. Cai coming soon and waiting for a good tuner. I'm sure it'll really come to life then. Go with the 6.2 if it's in the budget!

I love the way these V8 trucks sound especially the Hemi Rams!

I know this isn’t what the video is about… but the black trailboss looks absolutely sick with the 24s!

Great Video! I think the reason they raised the price so much for 2022 on the 6.2 is because they need money to pay for all the 2021 engines that had to be rebuilt!!!

Exactly how I felt moving up from a 5.3 👍

Solid video brother!

Great video. My 21 6.2 AT4 has way more power than my 18 Silverado 5.3. Once again great job

6.2 is great, I used to have one. I have a 5.3 now, and I’ve had several, and for me it’s plenty. Runs great, enough power for my needs. I don’t really lust for the 6.2. Call me crazy. Maybe I’m just getting old and boring.

I can't lie from MY perception you drove your truck more aggressive than the other plus there are mods done even exhaust makes a difference in performance but all in all great video‼️

Night and day. Over a second in the 1/4 mile is enormous. Great video!!! I love tests like this.

Awesome video, I got the 5.3L for a steal and added a Magnuson TVS-1900 and pretty much took care of power difference between them. The 6.2s are harder to come across but the price difference really isn’t bad between them if you find one.

I'll pretty much say everybody with the 5.3 would rather have the 6.2 in a perfect world. If I told you the 5.3 is just fine (which it is) doesn't mean they wouldn't rather have the 6.2. I do have the 5.3 and it is just fine but..... would rather have the 6.2. My brothers ecoboost is amazing as well but i like v8 push rods . But I am old

I have the 2022 refreshed Z71 Trail boss LT midnight edition with a basically 7 foot bed, and I love it! My truck runs great for personal use, for work, and off-road. If I needed more power, I might get the 6.2, but I can also do some upgrades that will give me that power.

I was a BIG 5.3 Fan, However bought a sierra with a 3.0 Duramax, and I love it. Yes it has issues, Long crank and 150K oil pump belt. But I've had ZERO issues with it and now have over 20K on it. About to change fuel filter with next oil change.

I love my 6.2 I got my fully loaded 2018 SLT z71 for 46K new. I test drove a 5.3 back in 2018 and it couldn't find its way out of a wet paper bag.

looking at the black trail boss with the 24s looks good shoulda bought a black one

That smile when you launched the 6.2 said it all

With the +/-1mpg difference it was a no brainer for me. 2020 TB with the 6.2l is quick. Most everybody who gets in is shocked how fast it is... Love it!

I really want the TB + 6.2 but the tiny fuel tank is a deal breaker.

Thank you I'm old and 5.3 is good with me great review

Do you have a video of the wheels and lift on your 6.2? Awesome video just upgraded to the 6.2

The 6-2 definitely sounds better. And with those bigger wheels and tires you have a lot more rotational torque to overcome.

That's really good. I have a 71 Camaro and your truck is right in par with it. I have about 330hp in a 3,400 car and my best 1/4 mile on street tires was 13.8@99.15 mph w/2.00 60ft. Granted, I only paid about $4,000 for that car back in 2004 so I can't complain too much. 😎👍

Can you do another test in your 6.2 with the pulsar turned up? I wanna see what difference it makes in times.

Is the black one stock? Like no level or lift kit? What size tires and rims did you put in it, the ones that came off yours? I’m looking for tires/rims for my 2021 gmc at4 1500!

Can't tell you how much I appreciate these videos. I ended up buying a 5.3 and while waiting for it to come in I saw this video. Ended up breaking the contract and getting a 6.2l and man I'm glad I did. These videos saved me

How about doing the same runs on the 6.2 with the 24” and see how that affect the numbers you already have. I really want to see the difference.

I've owned both,, just got the 2023 tahoe premier 5.3, but that 6.2 is just a beast of a motor. I miss that. 5.3 does ok, but 6.2 just hits different.

Awesome video!

I still can’t see the value in the 6.2. At the end of the day it’s still a truck, not a sports car. You’ll pay more for the engine option and here in eastern PA you’ll pay .80$ more a gallon. It’s not apples to apples. If they both ran in the same fuel, then I’d talk. With the 5.3 truck it weighs just a hair over 5k pounds and has 355hp, that’s not weak like most of you guys are saying.

Owned the 6.2 and it was a great motor. But I don't miss having to put 91 octain in and the 5.3 consistently get 2 mpg better. To be fair the right foot could have been a little heavier with the 6.2 😂

I have had bunch of 5.3’s on my first 6.2L in my 14 high country don’t think I could go back! Even getting in my girls Tahoe with tune and bunch of bolt ons and still feels sluggish compared to my factory 6.2 both have 3.5” on 33’s and 17” both have 3.42 gears and 6 spd just my 2 cent

I have an 06 SS 6.0 2wd and when I take traction control off she’s a blast! I can only imagine these 6.2s. Not letting go of my baby though.

Ended up with the 5.3 and it is a good motor but I still remember the 6.2 that I test drove. If I could have found the configuration I needed with the 6.2 that’s what I would rather have had. Though I am glad I don’t have to run 93. Great vid!

1st.....War Eagle! Second, I own both, both loaded Denali crew cabs. The 6.2 is not only way more fun, but tows and hauls better, and if you keep your foot out of it actually gets slightly better mileage on the same trip with all other things being equal.

Awesome vid and comparison…apparently I’m the only one with a new 5.3 that rips.

Great video man. We really appreciate this cool content.

Ive had both, love the 6.2 and I usually run 89-91 in it (depending on gas prices🤐) but with my experience I do find that my 6.2 is actually better on gas vs my 5.3 I had previously

I have a 2020 5.3 Silverado with a 63 series K & N cold air intake, D.F.M. shut off, Flowmaster Outlaw series 3 inch dual exhaust, 2WD, JET Pro Tuned Mass Air Flow sensor and the thing launches. Definitely not the same setup as your 5.3, but just giving props to what the 5.3 is capable of while still keeping some fuel economy.

I would love to swap a LT1 with a 10 speed in a RCSB GMT800. Too bad GM doesn't plan to offer the 6.2 and other trim levels other than the WT for the RCSB when they bring it back.

I have the 6.2 in a Black Widow Chevy 1500. With the upgrades in HP to almost 500 it rips, even with 22’s. I can break the 22’s loose without an issue at a standstill. When I put it in 4wd it just squats and takes off like a rocket. Love the truck.

I’m still salty I didn’t get my hands on a 6.2 but I blame China for Covid. Literally every dealership in my area all had 5.3’s only. It sucks but, I still love my RST.

The worst thing about the 6.2 is the recommended 93 octane. Mine definitely prefers 93. Lose on acceleration and some fuel knock with 87. Other than that they are great.

My 2018 Tahoe has a 5.3. I believe 3.73 rear end. It has a 6” suspension with 33x12.50 ….. maybe its just me lol but i feel like the truck moves. Im very happy with it. No problems catching up with traffic, merging on to highways etc

I have a '19 Sierra Denali 6.2 with CAI, exhaust, 22" wheels, 275/50 tires. I got 22.5 mpg (trip average) on an 85 mile 65-70 mph highway trip climbing 1600 ft elevation (~4700 ft-> ~6300ft), passing a few people, full bed, full tank, with wife and 3 kids, and then 28 mpg (trip average) on the way back all on 91 octane. I also pulled an 8,000 lb travel trailer 20 miles (flat no change in elevation) and ended with 16 mpg (trip average) on 87 octane (would have used 91 if I knew I was going to tow). This morning on my way to church 6.5 miles away (flat) my trip average was 24.1 mpg and 25.1 mpg on the way back and there's 7 stop lights, 2 stop signs, and a roundabout with 35 - 50mph speed limits (87 octane). So glad I got the 6.2. I wrestled with getting a truck for years, for fuel economy and practicality reasons, kept trying to cram everything into our SUV that I could get 25 mpg - 30mpg. I have zero regrets now.

Thanks for this video! I traded my custom 19 trail boss 5.3 for a 21 custom tb 6.2 10 speed. (Actually got the new one for 44,500) and traded the 19 for 43,500 lol) I clocked my 6.2 at 5.08 a month into owning it. Much lighter due to less options compared to the LT. Love these trucks.

Love my 2011 6.2. It’s a blast to drive daily on 93 fuel. But goes into total beast mode when I run E85 occasionally, since it’s flex fuel 😉

my dad has 2023 6.2L zr2 and that truck has some kick, but i love my 5.3 2018 Silverado redline.

what rims and tires(brand and size) what level kit? Love the looks of the black one with the rims on it

The 6.2 with the max tow 3.73 rear end is just flat out amazing. If you leave the traction control on you literally will still get great times. Well, at least if the road is dry. The 5.3 is a strong motor as well but it just doesent compare. 100 hp will do that to you. Throw in an exhaust and a CAI and not only will you tow like a beast you will surprise the hell out of guys who think their civics and subarus are fast. The 6.6 in the 2500 is stout "running that now" But with the extra weight of the 2500 its nowhere near as fast as the 6.2 in a 1500. Bottom line Spend the money, get the 6.2. More power!!!! argh argh argh :D
