Yukon designed gear tooth surface finish reduces both friction & heat for long races & high torque conditions. We use high grade steel in both the ring & pinion, with fitment designed to OEM specs. Go ahead, add loads of horsepower & go big on tires because Yukon offers the widest selection of gear ratios to choose from. You’ll know that your gear choice was the right one, because you chose Yukon.

Review: Quality parts for a very fair price - Using the complete bearing kit that I ordered along with the gears, the install was pretty straight forward. After about 4 mock ups, the gears went in fine. Even though I put a few hundred miles on the clock before towing, the temps got pretty high. I would say that before towing you should put over 500 miles on the odometer before towing. All is good now though. Temps 160 with 100 plus temps outside.
Review: New gears ! - Parts arrived early and look to be high quality, install was easy and no noisy gears now, run quite like they should ! Great value for the money.

## Questions & Answers

**Q: What install kit do I need for a 92 Chevy C1500?**
A: You will more than likely need the GM 3.73 Ratio/ GM 8.5” gear set. You have a 2wd so the ratio doesn’t matter a bunch, 3.73 is the most common. I changed all the internals of my 98 with these parts. They really didnt change em much throughout the years. Make sure you get 2 sets of new pinion bearings (1 set, inner races bored out to slide on and off easy for test fits, and 1 set for the actual final fit.) take your time and be very thorough. Look up EricTheCarGuy on youtube, he does an excellent video of exactly what you’re doing. Hope this helps.

**Q: Tengo una Chevrolet Silverado Ltz 4x4 z71 2014 5.3 tengo rines 37x13.50x26 me sirbe o cual me recomiendan**
A: for a 38" tire, id recommend 4.88 gears

**Q: what ring and pinion do I need for a 57 Chevy 3.08 gears?**
A: You need to know what rear or front end you have. For instance a Ford 9” or a Gm 8.8” there are quite a few different ones out there then match whatever ratio was stock or there is a lot of options depending on what you would like the rig to do hope that helps

**Q: I called them this morning they said its a 8.5 axel and 10 bolt**
A: This would be correct for your application then for a 3.73 ratio
