Fits GM 8.5″ and 8.6″ 10 Bolt Rear Axles.
This rear axle is found in the 1994 – 1996 Chevy Impala SS and many half-ton Chevy and GMC trucks.
The factory differential in these cars and trucks is a clutch plate design and applies power to both wheels only when going in a straight line, not around turns. The Truetrac applies power to both wheels in a straight line of course and also when going around turns, allowing you to put more power down, sooner.
Whether you’re drag racing, road racing, or just enjoying your vehicle, this is a fantastic upgrade that you will not regret.
This differential does not make any noise, and does not require any friction modifier fluid.
