Rating posi,gears and bearing kit for 8.5" 10 bolt stock nova rearend was a great value !
 
This kit was perfect for my 1975 nova. The price was cheaper than I could find anywhere online and the kit is of great quality. The crush sleeve was a little tough at first to torque but all else was a breeze. Great customer service. I e-mailed quick performance a question and instantly got a call from the company with my answer. Awesome company and awesome products ! Thanks. 75novacustom

Bought a Positraction unit with 3.73 Ring/Pinion. Really great people to deal with and very accommodating when I decided I wanted the 3.73 instead of the 3.42 originally ordered. Shipping was prompt and well packaged. Definitely will do business again.

Rating Very pleased with the product. Reasonably priced.
 
I have finally been able to test out the new gear setup. My 1979 Trans Am is running a 383 Stoker 426HP, TH350 Street/Strip Auto Trany, with your Yukon Posi Unit with 3.73 Gears. Very pleased with the product. Reasonably priced. Thank you, Michael
