what gains did you all see from 4.10s? I'm going 3.42 to 4.10

 

Yeah, that's what I'll do. There's a performance shop not even a mile away- I'll stop in and get a quote from them.

Sounds like this is going to be more than I thought, but it should be worth it in the end, hopefully.

 

So you already picked up the gears and master install kit right?

 

Just make sure if your gonna do it you need to suck it up and buy a locker too. Stock G80's go BOOM.. I'm figuring mine $1000 to $1200 gears,kit,locker,labor.

 

The more motor you have the more you will benefit from gears a stock 4.8 will not gain much, You'll see more bottom end gain and will lose top end 3.73s are really ideal for a street driven truck. Imo.

 

it cost me $275 to put in my true trac n 3.73s and that included the pinion bearing, crush sleeve, pinioon seal and oil.

 

Sounds like u got a good deal.
Fastgmc53 has a valid pt. If u can afford it, wait & install gears/ & a locker or similiar, all at once. It'll cost u more down the road if u end up doin them separate anyways. Not tryin to spend your $ for u, just sayin.

 

 

bumping this up... checking out what everyone is still paying.

I got quoted $350 for my 4.10, truetrac, and master bearing kit.

 

It was $350 for labor with me supplying the parts.
