They are Richmond 3.73 gears for the GM 8.5 10 bolt rear ends in our trucks. I bought them off ebay for $120 and never installed them. They are used and only have less than 100 miles on them. I've had a few mechanics look at them and all of them say that they don't even look like they have been installed before. I can send you pics if you want, just let me know. Make a resonable offer.

 

Any paper work or instructions with the gears.

 

No ,the guy that I bought them from did not inlude any. I would let someone that installs gears professionally, install the gears anyway.

 

$75 shipped?

 

anyone? BTW Chingon check your p.m.'s
