looking for advice on if I should regear or not. I'm not going to be towing, it's my daily driver with some off roading every once in awhile. I have the 4.8 l with a K&N intake and flowmaster exhaust. the guy at the shop says i'll be fine but after doing a lot of research I'm not sure anymore. i'd rather not regear but i also don't want to be dumping money into my transmission after a couple months of running this setup. thanks in advance for the help

My 4.8 with 33s was turd. 35s would just be worse. Can it be done yes. Is it shifting at any hill, yes

4.88 gears and a good tune

i'm running BFG all terrains that are 32.5" (275/70/17) and they run fine, i've had them for almost 2 years now. just worried about the strain it might put on my tranny

so where do the 35s come in to play?


and IMO, they should never have offered a 4wd truck with anything less than 3.73s from the factory

doesn't griff has 3.42s? or does he have 3.73s?

i'm going from a RC 3.5" kit to a 7.5"

there's no way in hell that a truck is gonna be happy with 35s and 3.42s unless it has a turbo

But what if his truck is 2wd?

many 2wd trucks came with 245s, not as bad with the 3.42s

The guy at the shop is wrong. I was running 3.42 and 35s for a while and I had the trans go out twice. I regeared to 4.88 and haven't had any problems so far but the 4l60e sucks in general IMO

6 speed? What was the original tire size?

 

[schunter11]

im running 295 70 18s (34.5x12) with 3.42 gears. i have a 5.3 with the 6l60e. its not too terrible but i drive like a old man anyways. will be doing 4.10s later on this year

 

[kkosa812]

6 speed? What was the original tire size?

it's a 4 speed. got the truck with 265/70/17s

 

[danj]

4.88s. Do it and never look back. Made my truck fun to drive again and I had 3.73s.

 

[Chitter]

With 35's you should go at least 4.56's, possibly 4.88's. You will regret anything less.

 

[kkosa812]

I've looked at some threads but what's it normally cost to regear? front and back? I know the parts aren't too pricey

 

[casz71]

Mine ran me around $2100 parts and labor iirc
