I feel like I already made a post like this, but now my back end is going out. If I am about to dump a ton of cash on something, I want it to be what I need. I am on stock gear ratios, on 35" tires on a 5" lift kit. If I need to get different gears in the back, then I am doing the front, so my question is, what gear ration do I need in the rear and in the front? I am 4x4.

4:56

In both the front and rear?

You have to put the same ratio in front and back. Do you tow any with your truck? 4.56 is a good ratio for 35" tires but it will hurt you mpg. If its your daily driver and you do not tow I would go 4.11.

Ok, I do not tow, nor do I have any close prospects of towing, thats what company vehicles are for lol.

4.10 all day long Yukon gears best investment I've made to my truck yet

4.56 for 35s

Yukons all the way. Call randy's ring and pinion. Jus make sure they send you yukons. My bro ordered yukon gears from randys and they sent him richmond gears but charged yukon price. He was pissed off but had to install gears to run his race car.

If you do the math it yields a 4.16 gear ratio to get you back to stock power, which you won't find... so 4.10 which is a huge difference, 4.56 you'll lose highway mileage and be up around 2500rpm at 70mph with 35's

If you just do city driving and rarely take it on the highway go 4.56.

My two cents for you

What is the difference between the 4.10, and 4.56? Right now after about 50 mph, my truck DOES NOT want to speed up any more, I can get up to 80, but it takes for ever. Which ratio will help me get up and go?

EDIT: I am mainly doing city driving, I do highway a couple times a month for 50+ miles one way.
