The Track 9 product series has been developed as a high-tech, high-quality replacement for the Ford 9'' Rear-end. Using state of the art CAD/CAM technology, aerospace engineers created a product of superior strength and reliability. A continuous 1'' wide, 1/4'' thick laser cut ring is welded to the front of the housing to increase the structural integrity and provide a precision surface to mount the gear assembly.
All Track 9 Housings (except the Ultra Lite) have close fit 7'' deep sockets for positioning the popular 3'' axle tubes. The ''fish mouth'' sockets are reinforced with internal gussets to assure precision alignment and maximum strength.
Housings and covers are formed from high tensile (High form/Spec A715) steel. This material is 39.9% stronger than conventional 1010 low carbon steel and is used in all Track 9 Housings.

Track 9 Competition Housing

Track 9 housings have been the exclusive choice of NASCAR racers for the past five years. They have been used by virtually every race team in Winston Cup, and by many teams in the Busch Grand National and the Craftsman Truck racing series. They are constructed of a 0.188'' steel body with 10-ga cover. Weight: 28 lbs. Built for road racing, circle track and off road competition.

Track 9 Competition-Lite Housing

Here is a Track 9 housing design, constructed of 10-ga steel to reduce the weight to 21.6 lbs. It has all of the strength features while offering the benefits of a lighter housing. Designed for circle track and road racing applications.

Track 9 Ultra-Lite Housing

For maximum weight reduction, Track 9 has developed the Ultra-Lite, weighing in at only 18.8 lbs. To achieve this, Track 9 utilizes a 10-ga steel body and 14-ga cover and has eliminated the internal gussets. This special housing is designed for competition where every pound counts!
