The Silverado Wins - We DRAG RACE a New Trail Boss vs a Z71 Silverado! 

Great info! Surprising results. Would love to see compared to the 2500 with the new 6.6 gas engine.

Andre's Homer Simpson impression "Oooh power folding mirrors" had me on the floor.

Great video, especially since I just bought a new 2020 4x4 Silverado LT with the 5.3 L and the 8-speed (3.42 gears). I got 22.2 on a 24 mile hwy run at 68 MPH on cruise control.

I just purchased a 2019 Silverado 5.3 LTZ with 8 speed non Z71 with 22 inch rims and love it Thanks TFLT for all your info in your vids

Thanks for the video, I knew you guys would put the pedal to the metal. This video confirms my decision to pick the trail boss over the LTZ. Really enjoyed the video.

Awesome video, love see chevrolet videos. My ‘14 Silverado 4X4, 5.3l & 6-speed Auto, still impresses me after 3 yrs of ownership and 160,000 miles later and still getting over 20 mpg on the highway. Love Chevrolet for Life. Thanks TFL.

Although the 10-speed gives a mechanical advantage over the 8-speed, the increased frontal area, and higher coefficient of drag on the trail boss decreases its efficiency because it makes it less aerodynamic. Also, the duratracs have parasitic losses due to higher rolling resistance, in addition to the higher rotational inertia. This is why the LTZ is faster, and gets better fuel efficiency. The conclusion from this video should not be that the 8-speed is better than the 10-speed, it should be that the 10-speed is having to overcome a lot of disadvantages on the trail boss in order to make the truck perform better.

I am partial to victory red, same as my 06 Silverado reg cab short bed with (factory) v8 and manual transmission, and 3.23 gears... and I still get 17mpg city without any of the cylinder deactivation or other fancy technology bits, thanks to the 4200 lb curb weight and manual transmission.

Cool video. Wonder how the six speed in the 2018 model do against these two. Would be good to know the suttle differences.

I missed the drag races, good job guys!

Wow the powerfold mirrors are amazing! My 07 f150 has that with autodimming

Trail Boss looks very aggressive. I like it! In Italy the Trail Boss is imported and costs € 63.000 , about $ 68.000

I know there's a lawsuit on the 8 speed but there is a lot of people that like the 8 speed. Also I've heard that people say when they deactivate the amf/dfm the transmissions shift better. Makes me wonder if the maybe there isn't so much of a problem with the transmission but maybe it's the cylinder deactivation that's causing the issues. 🤔 Has anyone else heard of this?

Silverado wins !!!

Now do the TB vs the AT4!

Awesome Stuff Guys! Hoping to see a Silverado Trail Boss 5.3L V8 10-Speed VS F-150 FX4 5.0L Coyote V8 10-Speed in the Future.

I’d like to see a highway mpg loop see what they are getting when just cruising

Pretty crazy that you CANT get a 10 speed in the LTZ. They must want him to get the 6.2 or the diesel

Those Silverados scream "In your face!"

Both are adequately fast. Fun video though. I know that someone mentioned more gears takes more time to shift but really these were probably both only in 2nd gear by the end of that race. I wonder if the lift may have had something to do with it. Taller truck may take more time for weight to transfer on hookup? IDK results are certainly not what I would have expected. Maybe the computer in the 10 speed is pulling power in 1st gear to protect it?

Chevy baby! Thanks guys. Great vid. ☘️

be interesting to see one of these trucks go around the track, curious if it's as bad as we think it'll be

I asked Chevy why you could not get a Trail Boss in LTZ trim at on the inside. Needless to say I haven ' theard back from them! Great job guys on these tests . These two models are the finalists for my next truck!

Wow! I seen the video was over 14 minutes long and though to myself, they filmed the entire 1/4 mile race...

Haha "expensive cameras flying" lol good video guys

I have the GMC version and those duratrac tires are extremely loud on the road and when i switched over to a BF KO's i notice a big fuel economy jump also.

This was shown when the camaro went from the 8 speed to the 10 speed too. The times were exactly the same. But I would never get the gm 8 speed. So many problems. The 10r80 is still superior.

5:52 Your welcome

Another life lesson where I think the bigger number is the best option and find out it's not what I thought it was... still learning this over and over again.

Can you guys get Into suspension optionsand what they mean? I have a z85 suspension on my 2004 3/4 ton sierra which rides smooth for a 3/4 hd and it's smoother than my dad's 1/2 ton with z71. I've looked up z85 and can't find a clear answer. Some say it's shocks others say level kit or body lift to.

Both awesome trucks... great video

Pretty surprised by the results as the LTZ has to be heavier and with the 8spd. But I guess the extra height and off road tires really do make a difference.

I'd buy a dark blue RST z71 Silverado right now if there were any in stock in my area. This video just decided me over the trailboss. gas mileage and 0-60 speed. been waiting on this comparison for a while.

I don't go off road so the "Silver"- ado is for me.

"Expensive cameras flying" Hoo man, I know that feeling. I've broken a DSLR lens that way.

Can you guys also do this with the new 6.6 gas & duramax? Would be sweet

One thing he didn't mention about the Z71 package I found while shopping for a Chevy truck- Without Z71 you only get a one speed transfer case- that's right no 4Lo, only a terrain control which is an electronic crutch that uses traction control like braking to "pop" you out of a rut by essentially torque braking! So far Silverado is the only full size 4WD to not give you a 4 Lo- I guess they want to make a few hundred more dollars per unit hoping no one notices!!!

Great video! If it were all about drag strip times we’d all be driving 6.2’s or Ecoboost’s my lil 2.7 Ecoboost will leave a 5.3 sitting, but which engine is capable of 300k, I’m hoping my lil engine will get there, but I have friends with 300k on their 5.3’s. My truck has a lowly 6 speed and I like that, honestly talking to other 2.7 owners with the 10 speed my truck gets better fuel economy, but I’m older and wanting the truck to go 300k+. Wondering if you’d put Big Daddy Nathan 1/4 Miler in the 10 speed would it had made a difference? Still awesome video!!!

I don't like chrome either, but that LTZ is so luxurious. I'd have to go with that. My mother in law has one and I'm always looking for a reason to borrow it.

I want to see a drag race between 2 more chevys same truck same motor but with different transmissions just to see if the 10 speed is that much better

Im swapping l83 5.3 in my 80 cutlass supreme its a 6speed planning on racing hope I win alot of races 🏁 going to make a RU-vid channel showing my results

Should’ve thrown in a 5.3 6-speed just for shits and giggles.

This is a very good comparison. I just recently traded my 2019 Ram Rebel after 2 years for the GMC Sierra AT4. While I still feel my Ram Rebel was hands down far superior in interior fit/finish/materials, electronic functions (driver display center, and UConnect system), and just about every feature of the interior, ride quality was also superior. But I was still very unhappy with Fiat/Chrysler for misleading fuel economy figures of the Ram Rebel. I drive from Florida to the midwest multiple times per year and the Rebel's fuel economy was absolutely dismal. The AT4 I purchased is loaded. The fuel economy was spot on what I expected and averages 3-5 mpg higher than the Rebel. As for your test results, I believe the tires are more to blame. My AT4 came with the 20" tires, but I did not want to pay the $899 for them so I had to wait till the dealer got the 18" Duratracs in. I drove 2 tanks of gas with the 20's before installation of the the 18" Duratracs were complete. Mileage dropped 1.5 mpg. So overcoming the beefy tread of the Duratracs takes away from both performance and economy.

Great video!, any chance you can race the half tons against the midsize class at some point or is that sac religious?? 😁. I feel like the Chevy Colorado could hang with these two trucks 0-60 at your local track? 🤷🏼‍♂️, Thanks

Its the heavier tires on the trail boss for sure. More Rotating mass will surely kill acceleration and efficiency. Good video. Oh and Thank you for saying "pounds-ft" and not "foot-pounds".

Would like to see this done with the new Range DFM disabler (full V8 all the time). My '19 Z71 drives so much better now. I took the hidious air dam off in about 15 minutes.

I have a high country with 10 speed love it

Hello tfl can do test the 2020 Silverado 1500 high country with the 5.3l v8 and 10 speed automatic transmission because I would like to see you test the that truck with many tests.

I love these trucks. Very interesting stuff.

Andre. Fun video. Just a nit, the differential ratio is the same front and rear. If you can’t open and close your tailgate you should be driving a Honda

Project truck? What projects have you done to the TB since you bought it 3-4 months ago?

can you do the 2020 5.3 wih 6spd that comes in the customs also

Very interesting. Just curious, did you guys use same octane gas?

Shows the extra gears are mostly to get a bump in fuel economy and emissions ratings and maybe more pleasant towing, not necessarily for speed

Can we get the trail boss vs Ford F250 7.3 V8 drag race

Drag the 2020 2500 HD with the 6.6L gas engine against the 1500.

I’m currently driving a Charger Scat Pack with close to 500 HP, and I’m seriously considering a TB. I don’t know why I’m worried about a reduction in HP with a truck. When I drove a 2010 Silverado LT with 310 HP, I thought it flew so I imagine the TB is a huge lighter upgrade

Trailboss 32.1" tires with the 18" wheels. (275/65 R18) LTZ 33" tires with 20" wheels. (275/60 R20) That means the trailboss has a gearing advantage with the smaller diameter tires. That combined with the 10-speed. If both trucks had 35" tires or larger then the advantage of the 10-speed would be more noticeable. 10 gears gives you more headroom to throw on larger tires without having to change the rear end ratio to compensate. I think that's why they slapped the 10-speed on the Trailboss.

I'd bet money the difference is in the torque converter tune. The 10speed is tuned for economy so the torque converter probably isn't going to be as aggressive with stall speeds. Even though the 10 speed's first gear 4.70 is slightly shorter than the 8 speed's 4.56, a higher torque converter stall and more aggressive ramp up would make the 8 speed quicker off the line.

Is the Canadian guy with the beard still part of the team ? Have not seen him for a while on your channel

I’ll say it. My 2014 was and still is a fun truck to drive. From stock it topped out at 110 but for some reason my brothers 2020 Silverado tops out at 95. Now I have lots of work put into it and tops out at 160, 140 on the dash but in the display it will show you how much faster your actually going than the needle gauges. Idk if that can be done on the newer 2020s 🤷🏻‍♂️

I think 6-8 speeds is enough, on my F-150 I think 10 speeds is too much. The 6 speed in my Lincoln is perfect for acceleration off the line and for low revs on the highway.

It'a probably too late to test, but what would be interesting is to change the tires and wheels from one truck to the other and then run them again. You may find it is all in the tires.

I'm going to be one that complains that not everything is matched. Tires can make a difference and your MPG shows this at the end. As for which I would take it would depend on what I am buying it for. If I plan on using mainly on the highway it would be the Zed if using offroad it would be the Trail Boss.

Let's see a 2018 Sierra Denali 6.2 vs 2019 or 2020 Sierra Denali performance and MPG review!!

Do the lifters still fail in the 5.3 I want to buy one but scared lol

It was a great test. Definitely chevy guys out there deciding which $55k truck they will buy.

Takes time to shift. More gears MORE TIME!! Why do you think two speed powerglides are really good drag race transmissions!!

I removed the air dam on my silver LTZ, and my God! What a difference. No change in MPG at all. And I'm supprised you found an LTZ without the Bose speakers. You got ripped off on that.

How do you make the lights do that

Should of done custom trail boss 6 speed vs the LT trail boss with the 10 speed

I haven't met too many people who are happy with that 8 speed. I'm sure there are some, but I haven't seen it.

10 speed might still be quicker than the 8 speed. you might see the 0.4sec difference just in tires and the lift

Question ... How did you get the front lights to strobe ?

Same 3.23 gears but taller/heavier tires on Trail Boss makes it accelerate slower, even with 10-speed. Needs a 3.42 or even better, a 3.73. And, might as well throw in the 6.2L too. 😆.

Would have thought the 10 spd had advantage, but tire weight, tire height impacts gear ratio some. As for looks, I still like to see some chrome, the silver truck looks classy, but some like blacked out look.

I like LTZ its has so chroms on the front, and if its come with 6.2 L it's will be really incredible!!!

No surprise. The Less shifts the more power you get from engine on every gear on good transmission. There is a reason drag cars have a 2 speed transmission in most cases.

I have a trail boss but how do I make the front lights flash the way they did at the beginning of the video? Anyone know the feature to make do that?

Nice could guys do the 2020 GMC Denali sierra vs 2020 AT4

Any issues with the Silverado lifters?

What is the weight of the 18” rims & tires vs. the 20”? That unsprung rotational mass might be your difference.

Can we see a drag race with 5.3 ecotech 6 speed transmission vs the 5.4 ecotech 8 speed transmission

I have the 8 speed RST and it’s pretty fast 💨 and could tow 9800

I am a big fan of the Silverados but I have to take issue with those gill plates on the front side of each fender. In the winter time filthy salt spray from winter driving on slushy freeways builds up in those slats. When the temperature drops below 20 it would take you $10.00 in quarters to try and clean the dirty ice out of there at the spray wash. Even in the summer it seems as if they are dirt traps that are difficult to clean.

I put an intake, exhaust, and king 2.5’s on mine and it is a different truck let me tell you. I have the 8 spd and it’s really quick for a big truck.

What beautiful trucks!!

Rear end gearing difference?

I wouldn't worry about difference between 8-10 speeds. It will never be as big as going from 4 speed to 6 and even 6 to 8. This race would be interesting with a trailer.

So what are the differences between Z71 and trailboss? Spacer lifts?

At 9:01 seconds Andres upper lip action he felt bad ass lol

I have driven both and I would take the LTZ, but don't care for all the chrome. Also for been so different they were not that far apart in performance.

I'd get the Z71 Silverado, both are nice trucks rather have chrome grill instead black mesh grill.

Next time do a Custom crew cab short bed with the Custom Value Package (in black) vs a Custom Trail Boss crew cab standard bed with the Dark Essentials package (in red). That’s what we want to see.

From which video is that off road part from????

I'd like to see you swap wheels and tires between the trucks and see what they do. I'll bet that is the difference more so than the transmissions. Off road tires kill 0-60 and mpg.

My 05 Chevy 1500 has power folding mirrors that many years apart and that’s all they have?

Very surprising results honestly especially considering the LTZ has taller gearing with the 8 speed and even has taller tires to boot. Assuming the LTZ has 275/60/20, that's a 32.9" tire and the trailboss has 275/65/18, thats a 32.1" tire. 8L90 1st gear ratio is 4.56 10L90 1st gear ratio is 4.70 I'm assuming both trucks are 3.23 rear end Maybe the silver truck is just a factory freak lol

How do you make the lights flicker like that?

But wait...stay with me Jimbo, stay with me, theres more!
