Never done gears in a 4X4, but Richmond Gears have lasted 7 years on the drag strip for me (and still going). Dont think I would run anything else.

Richmond, Precision, Yukon.

 

I have used Yukon Gear in 11 gear swaps. I recommend them, I have only had problems with Sierra. 2 Sierra Gear sets failed.

 

For the Do-it-Yourselfer with a NBS GM Truck I would NOT buy GM Gears. Motive used to make the gears for GM, but in 1999 GM switched to another company that cuts the gears differently to cut down on gear noise. This cutting technique requires backlash so tight you cannot get an accurate pinion depth pattern.

 

I deal with Randy's Ring and Pinion. http://www.ring-pinion.com
