1967 C-10 rear axle
Works great, looks great, have no complaints. Just wished I would’ve read the full description before purchase. I picked this up with the intention of removing the existing factory gear ratio but upon further inspection this was designed with the 3.73 and up rear ratios. Still installed it with the factory ring gear and it works great! The shim and bearing kit was easy to install as well!

Good Product but different then stock chevy posi
Great posi, out of the box it looked great and had good looking parts. assembly went great. Gear pattern very close to stock carrier with stock shim thickness. Spider gears wear good but leave some to be desired in terms of pattern worn on them.This is a different posi compred to the stock chevy/GMC versions, clutches only used vs the original G80 with centrifugal weight system + clutches. The drive feel is a bit different but not too annoying. Get an extra set of clutches yukon (composite) or eaton (carbon fiber), youll need them within 6 months of light wheeling. Eaton set bites harder and last wayyy longer.

Don’t cheap out
Whines going down the road and grinds turning, don’t even bother with customer service it took me four days to get in contact and then they just told me to change the fluid even though I used exactly what they recommended.
