Yukon Gear Dura Grip Limited Slip Positraction Unit For gm 8.5"/8.6" Differential With 30 Spline AXLe, 2.73-And-Up Ratio, Ydggm8.5-3-30-1

Well built. Works great. Installed in my truck for towing and in-the-woods hauling capabilities, replacing a stock open carrier. No issues, and I have put about 200 miles on it since the install (don't drive that truck much). No abnormal noises.

Muy satisfecho, calidad, precio y todo en tiempo

Originally purchased one of the from a company in Wa state for double the price, this is a wholesaler which cuts the price drastically. Exact same packaging, product (stamped from manufacturer w/ serial numbers and everything), excellent customer service too. If you need a new locker for your gm 10 bolt this is the best option to replace the stock g80 (gov-lock/ gov-bomb). Ran my first one for 150k miles, didn't know fluid replacement was crucial to clutch longevity. I'll be changing this diff gear oil every 30k. True Yukon gear part, exact replacement for almost all gm 10 bolt rearends. Don't believe the -2 at the end of the part #, it's a ydggm8.5-3-30-1 made in the USA. This was less than half price from the local company that produces them, that company wanted to rip me off, this company sold me my parts at a reasonable price. I'll be recommending them to everone. Thank you very much.

Lo compre para un trans am 78 y en todos lados solo menciona que es para flechas de 30 estrías lo que no menciona es que el diámetro no es el mismo, también los baleros de los costados no vienen en los kits normales para este tipo de diferencial hay que comprarlos por separado

Very impressed with this posidrive, takes all the torque and some. The only thing is make sure to use a bottle of Yukon anti slip and good to go.
