I was quoted $750 parts and labor going from 3.55's to 4.10's. You can buy cheaper gears and most shops will install any gears you bring them if you provide the parts, but I was told by a couple of shops that they will only warranty parts they sell. I was also told that Yukon gears are the best you can buy and that was quoted from 2 of the 3 shops.

 

Weird! I'm dropping off my truck to get 4.10's tomorrow as well. I'm running OEM 20's though on stock rubber and mine's 2wd. I'm hoping for a nice performance increase.

I'm getting it done for $804 out the door.

 

Where at?

 

4WP. I ended up going there after a re-quote.

 

4.10s are nice middle of the pack gears for all around performance. Not much impact on gas mileage with my 32" tires. Got my 2WD done for about $650, however, that was about a year ago.
