Gear Ratio Change

[rgiles675]

I have a 4wd Sierra that has a 3.08 gear ratio and I want to move it to 3.73. My service rep said that I am able to have a third party do the work and keep my warranty. How much am I looking to have this done by both a 3rd party and the dealer?

 

Thanks,

Ryan

More than you want to hear.

 

Even worse: the 3.73 is not available in a 2014 1500. 3.08 or 3.42 only, with 5.3. Scratch that: it is available with the Max Tow package, just not as a normal option.

 

It would be more than a thousand I'm sure.

He does have to use OEM gears. He can use aftermarket gear and pinion set.

 

 

At a good reputable shop (not the dealer) you'll prolly pay $300-$400 per axle for labor. Plus whatever your cost for parts is.

 

At the dealer i wouldn't be surprised if they charged 1000 per axle, then marked the parts WAY up.

Rear gears are supported by the aftermarket suppliers? Heck, we just got taillights.

If you can find aftermarket 4.10 gears I want to know! I have been looking and don't see any.

Yes and I bought it exactly the way it looks in my pictures from GMC. They do a project truck every year....It drives great and nice with the tires and lift believe it or not but I just want the extra umph 3.73 gears would give me.

If you spend the coin to regear go 4.10 if not go 4.56. don't waste the time for 3.73.

 

I think some have already went to 4.56 using the old carriers. I'll have to see if I can find the thread.

No problem. If you find a set of 4.10s for the 14' let me know! I haven't seen any.

Same goes to you!

Hey all! Looks like East Coast Gear Supply finally put the gears on their website for us! It's listed only for Chevy 1500 5.3L but I'm sure it would fit the Sierra 1500 5.3L as well. Can't see why it wouldn't.
