Hey guys I was wondering what front diff. I have in my truck, its an 88 RCSB GMC Sierra SLT with a 350 and the 700R4, I want to lift it in a year or so but I need to what size my front diff. is so I can regear. Thanks

 

[thArf]

8.25

so if you lift it in a year you will regear in two?

i dont know if yukon gear will still exist in 2012

to be honest i would probably keep your truck as it is and then set fire to it when you get it stuck in the mud - say it was stolen

except it was my step dads and I plan on giving it to my first born too and I love this truck to much, I think I would literaly cry if it was stolen or caught on fire, I learned to how to drive in it

 

[Crunk]

i'm the same way with my truck, first vehicle i've ever owned and learned to drive in plan on giving it to my child too

 

[thArf]

i know the feeling

I have an 8.25 with 3.42s in it if you want to buy it.

 

[tylers88]

I,ve got the 3.42 and like them, can roast them for days if I want but I can pull 16-17 mpg on the highway, I want to get something that would figure out to be the sameish as these with 38.5

 

[LiftedVictory]

you aint gonna get 16-17 with 38.5s. you can have the same power with 5.13s, but your truck aint gonna handle it too well.

 

[Crunk]

get 5.13's fa sho :read:

 

[LiftedVictory]

Yup.

 

[tylers88]

I dont plan on getting good gas millage with big ass tires but I meant still have the same feeling as far as power and torque goes

 

[LiftedVictory]

5.13s, you are gonna kill your front suspension and drivetrain components, and that 10 bolt rear is gonna blow up on you. I say solid axle on 1 tons if you plan on that.

 

[Crunk]

:word: IFS + 5.13's = FAIL

 

[LiftedVictory]

IFS + 38.5 + 5.13 = Epic Fail.

 

[tylers88]

Is there any differance between the OBS 1/2 ton and 1 ton front diffs, it seems like there should be?

 

[thArf]

yes i think the 1 ton is a 9.25 but im probably wrong

also 5.13s arent EPIC FAIL they are actually pretty WIN i just would avoid the bias plys and monster truck gears for a daily driver

 

[chevytaHOE5674]

yes i think the 1 ton is a 9.25 but im probably wrong

Correct.

And it will NOT bolt in place on a 1/2 ton.

 

[tylers88]

Correct.

And it will NOT bolt in place on a 1/2 ton.

well damn that plans shot to hell, and this wont be a daily driver, just a weekend toy and maybe 1-3 times a week and not like road trip type comutes either
