2012 GMC Sierra 3.42 to 4.10 Gearing Swap 

Wonderful

Living the dream!

Gary Stefanik adult owned, all highway miles.

you forgot non smoker

never towed with , original owner

"Never banged my cousin in it I promise"

"no lowballers, i know what i have"

Oh ya "just fuckin dandy"

Tires too

Lmao 😅

Thats what i was thinking

Hp would help

@Dirty Martino I have a 2012 3.42 gears on 35s spins no issue at all

Nah bro my 04 Yukon with the 5.3L VorTec in it won’t burnout even with the stabilitrak and traction fuse pulled. Got any tips?

Dirty Martino not positive. I just had all them done with new calipers and lines, but it used to lay rubber before I had to replace the engine. After that it won’t break traction unless the road has a wet spot.

You're only the 2nd person to acknowledge that, thank you. And yes, it helped a ton!

I went from 3.23 to 3.73 on my 05. It’s a 4 speed auto too. I couldve went 410 since the different between 3.73 and 4.10 us only 200 rpm but I’m happy with 3.73. I just talked my buddy with your same truck to gear swap to 4.10. He Tows a 26’ toy hauler with 3.42 gears and he said it struggles.

I build transmissions as well as gears never have rebuilds

hos that bro i whant my truck to do buenouts what can i do to it

Lol'

Chris Robinson thats what i do and it works half the time

mncarguy I'm only 17 and plan on buying a 2009 Silverado. first question is besides the burnouts what will the gear ratio change like mpg or stuff. second is if I get both front and back at 4.10 I will still have 4wd no warning lights on dash or anything.

Playdowstare zeyoutuber I lost maybe 1 mpg after getting them put in. It sits around 2200 rpm when cruising at 75 mph and it tows stuff much better now. There won't be any warning lights on the dash or anything. Only thing you need to do after installation is have your speedometer recalibrated. I still have no regrets of having mine replaced.

Nice thanks dude have a good one.

You too. Good luck with the new truck!

I want the 4.10 swap for my 07 Sierra but I do a lot of high speed driving on the highway and like the acceleration I get 50 to 90 really don't want to lose my high end acceleration but I like those burnouts, really cool man.

Thanks and will do! This video was expensive and took forever to make but it was fun.

Hell yeah man! You're the first person to say anything about the BxD part.

cool story bro.

There's a few things. It could be the low stall of the stock torque converter, your rear brakes could be too strong or your truck just doesn't have enough power. Your best bet would be finding someone with an HP tuner and have the torque management dialed back or completely disabled. Hope that helps. Let me know if you figure anything out. I had a cammed 6.2L swapped in last year along with a 3000 stall converter. It has so much power that the tires will spin even with traction control on. I'll be doing a supercharger next and it's gonna be fast as hell lol

Yup, the truck exploded on the way home. There were no survivors.

mncarguy lmfao

Thanks!

mncarguy you're welcome

mncarguy good job dude.

Rock and roll man! That's sweet

ya the 2016 probably has more power and may a better ratio

And you payed 50000 to do a burn out

+Legobropresents lmao. nope. less than 50gs. and it's an ltz sukka

same thing on 2014, turn off the traction control and it does a burn out.

I had an 07.5 GMC Sierra and stock with a throttle body spacer and 31" mud tires it would roast the tires It would take a sec for the drum brakes to release but when it would do a burnout and I only had a 4.8 Which from my experience is faster than a 5.3 when both stock

The brake bias on 07-13 is what’s the problem

Finally someone who understands! Thank you for restoring some of my faith in this website sir.

Out of curiosity why is it setup​ for wheelchair accessible

I'm also curious how it works

What does that have to do with throttle management? My dads tahoe is wheelchair accessible and would burn down to the rim using the hand controls if you wanted to.

He presses down on the brake to damn hard when he does it I have a 2009 5.3 with the stock 3.42 gears and It can do burnouts like his without my brakes squeaking like their going to fall apart

And cash to get his trans rebuild

Denali's come stock with 4.10 gearing so that high of gearing shouldn't intimidate anyone. My truck sits at 1800 rpm when I'm doing 70 mph on the highway and I still get around 11 mpg with e85. I can even go 125 mph if I want to. So they're very streetable.

What he really needed was a GM Cold Air Kit, would of roasted those tires even better.

I went from 3:73 with 35s to 4:88 with 35s and got better mileage all around ls engine have a sweet spot higher in the rpm range than a typical engine. my burnouts are hellacious with 4:88s but I also got rid of the junky ass 10 bolt and swapped a 14 bolt semi floater out of a heavy half ton.

Ryan Stansel Bull shit.

okay.... I would "bullshit" about something like that. no its true it doesn't take as much power to turn the wheels to get them speed. what does it take to make power? energy. whats is energy in a vehicle? gas you use less gas to turn the wheels. in all you get better fuel mileage. also the transmissions in these trucks have really high gears. I can do 80 wih 4:88 gears and 35s at 2700 rpms. you gotta think we also have converter lockup. my truck has a 4l60e. his probably has a 6l60e with ould make his 1st gar lower then mine. I know all about this shit man. I built my truck and could tell you anything you wanted to know about it and anyone like it.

Ryan Stansel You are not turning 2700 rpm with 4.88 gears at 80 mph even with 35 inch tires. I'm very good when it come to gears.

I'd see about getting a decent tune done by a performance shop if I were you. Or if you're really serious, invest in a better torque converter. Something with like a 2800 stall. That'd really wake it up. Either of those options would cost less than regearing it. Unless yours is only 2 wheel drive..

Joe Bs did one with the tc on the new 5.3 ecotec and without tc as well

I can do a burnout easily in my fullsize truck with a 4.3L V6 so this guy should have no problem lol

CodenameHaswell he was dragging the brakes way to much

Why would you buy a full size with such a small engine?

Joe Bs he probably also didnt slowly release while smashing the gas

1sikR6 Oo its because this guy has torque management on his truck

1sikR6 Oo my dads 09 gmc only has a 4.8 and burns out like crazy all you have to do it unplug fuse #9 to disable torque management and it breaks them lose so easily

QuadManAustyn99 do you know if the 02 silverado have that fuse too??

It shouldnt because it has a throttle cable and not drive by wire

1sikR6 Oo so basically when you floor it the throttle plate will be completely open and the computer wouldnt be able to control it

Lmao 😅

Yeah, says so right on the dash. You know that, right?

Hpr1993 I can do one in a 4.8 it’s just the driver

I have the same problems and i gas on the pedal when i do it and it still dont go more then 2000 rpm

I tried turning off the traction and abs still not working

do you have something done to it becuase mine its was even spin the tires and i have a 4.8

Will do

thats all that matters is if you're having fun! cheers!

No performance increase though..

+mncarguy yea that's true. Did you get the front diff regeared yet?

Yup, she's all done. The pulling power is amazing now too.

+mncarguy cool, your going to need that 4 wheel drive this upcoming winter because we are going to get a lot of snow, or at least I hope so. Last winter sucked for snowmobiling.

That would be sick! Maybe sometime in the future.

mncarguy or a Toyota pickup. they all come stock with 4.10 gears or higher.

Gabe Forney true . My 4 runner had 4:56 from factory

@@gabe147147 damn I guess that's why my Tacoma is slow af but goes the same speed while pulling my rzr

Omar Aguilar its nothing to do with anything on the vehicle its just that it has torque management so it cuts power when given full throttle the amount of power cut is enough to make sure the tires don't break lose with stock gear ratios but its not enough for the 4.10s so it burns them but as you could see it still had a little trouble because of torque management there is away to disable it by pulling a few fuses my dad does it all the time and has no problem roasting the tires

Thanks! Should be getting some more performance upgrades in the next month or 2.

Works good in mud and snow

i was crying hearing it shift so much

Pumping the gas wouldn’t be a bad idea either if he putting it in 1 Gear

I'm running 2.25" true dual exhaust, a Flowmaster 40 Series muffler and 1 3/4” Pacesetter long tube headers. Couldn't be happier with how she sounds! I'll be putting a supercharger on it so I'm gonna upgrade to 1 7/8" long tubes and 3" piping next year. Here's a more recent video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JaDSwlC6X_Q.html

Steve Duval. My thoughts exactly . these guys dont use the line lock anymore when i was a kid i had line locls and mffler cutouts valves on every car . we would pull to a stop set line locls to bypass rear brakes then pull a lever in front of seat to allow exhaust to dump 4" away from cat it would cause anyoneto turn and watch within a 1/4 as id blow a weeks pay smoldering tires while feathering the front brakes with my left foot. Wow i feel 18 again just talking about it. Simple things to do and both for under $300 maybe 5 or 600 now but at beats tuning re gearing and still setting rear brakes on fire

Mine too 02 silverado

We dont have a severe torque management system like the newer trucks. Ive got a fully loaded 2000 ext cab LT silverado, and there wasnt really a way or a need for them to do it to trucks back then. Now theyve gotta make everything safer and more drivetrain friendly so idiots dont crash. Lol

You can't use 4x4 until you re gear the front as well. The transfer case needs nothing.

Ricky Creason it should do it stock my dad 03 has no problem its before they added torque management so it should have no problem

Ricky Creason just do them both at the same time. and not worry about it.

Micah Mcdowell i suspect he was having an issue with the rev limiter. it wouldn't go past. 2k

Micah Mcdowell I own a 2012 gmc Sierra 1500. It limits it to only 2000. It's the terrible torque limiting and afm dod

Thanks buddy! I'm running true dual 2.25" exhaust with a Flowmaster Super 40 Series muffler and shorty Pacesetter headers.

Well, the fastest I've gone before the swap was 125 mph but I ran out of room. So I never top ended it but it can still easily do 125 after the swap as well. The overall top speed has decreased from the swap but it's so high that I haven't even noticed.

T Parrish wheres the video???

Been a year? Still no vid?

No lie, when I had a ram I could roast the tires. Now that I have a Silverado it makes me miss my ram. If I ever am in the market for another truck I'm definitely getting a ram again

zags I was about to say this guy is just light on his pedal. My 06 5.3 can easily roast tires

yeah exactly and i know them older 5.3s can roast em good to so theres no reason he couldnt have done it with the 3,42s these 5.3s have 15 more horse lol or hes just leaving it in drive and tranny is trying to shift

Ryan Cowles you guys are right he's kinda weak, the only thing you can't burn out in a 5.3 motor is a suburban , you'd need a 5.7 their to heavy

my 2003 5.3 fucking roasts them, and it runs like shit!

It was $1600 for the front and back. That's including parts and labor.

i call bullshit, unless you a single cab you probs dont even have a truck

Doubt it mune has trouble braking then loose some times woth bolt ons and tune on a 5.3

The gears alone will help a lot because you'll have much better acceleration

Expensive clouds at that lol Thanks man!
