Review: Good gear set - This is a good quality reasonably priced gear set. I installed this in my 99 square body suburban 10 bolt 8.5". The ring and pinion had previously been replaced in my truck before I got it. Unfortunately whoever installed that didn't clean out the meatal chunks from whatever bearing let loose previously and it caused the inner pinion bearing to go bad(as well as spider gears), no one cared and just kept driving it. I tried replacing the bearings and cleaning everything and just could not get a good gear contact pattern. I washed my hands of that set and bought this. Set up was nice and easy. I used a straight edge across the carrier bearing cap mounting flats with a dial caliper to measure pinion depth, then just had to adjust shims a few times for ring gear backlash, checked pattern and it was great. Put it together and for the first time since I've owned this vehicle there's finally no noise from the differential.
Review: Very well made and QUIET gear set. - When my 1971 Nova had rear end issues, I was on the fence about which manufacturer gears I wanted to purchase and stumbled onto Motive. Yes, they are manufactured overseas but, if you or your shop follows the instructions for installation, they will be wisper quiet. Set them up to have a .007 to .009 backlash and do some light driving for 500 miles and enjoy.

## Questions & Answers

**Q: will this fit my 2009 gmc sierra 1500 sle rwd it has an eaton g80 locker with stock 3.42 but want to switch to a 4.11?**
A: Yes but I'd replace that g80 with a detroit truetrac before it breaks and eats up the gears

**Q: having problem finding ring  and pinion gears for my truck   39/10  ratio  1960 apache 1/2 ton 6 cyl  want to keep orig. new or good used reasonable**
A: You have a GM 9.375 rear axle, we have not seen new gears for your applications in the last 15 years. We do have a bearing install kit #R8.4RMK but nothing on the ring and pinion new or used. 
Thank you

**Q: Does it work 1980 Camaro 4 speed manual transmission?**
A: The 80 Camaro will have the 10 bolt 8.5 rear axle and these gear will fit. But you need to know what your stock ratio is if it is not 3.08. The 10 bolt 8.5 does have one carrier change at 2.72 and numerically higher. So if you are below numerically than 2.72 you will also need to change the carrier.
  Thank you

**Q: will this fit my 96 impala ss 8.5 10 bolt?**
A: This is an 8.5 10 bolt gear
