We now offer a stock steering rack in order to avoid the long lead times required on custom-made racks. After many years of ordering these racks we've found a common size that was frequently ordered. That size is now available as a stocking item for immediate delivery. The specifications for this rack are as follows: A=18" B=13" C=10" D=1.5" T=1/2-20 (see drawing). The rack travels 2.54 inches for each full revolution of the pinion, with 3 inches of total rack travel. 9/16x36 spline pinion, lightweight aluminum alloy housing, and steel rack bar. This rack is an excellent choice for original construction such as sports racers and Formula SAE cars. Weighs just 5 pounds.
Whether you choose a stock rack off the shelf or a Custom Steering Rack (Part No. 1800) made to your specifications, you will get a top quality unit engineered for smooth operation and long life. Unlike most racks which bend the rack towards the pinion to achieve optimum backlash, this design moves the pinion towards the rack in an eccentric housing. This has the obvious advantage of a much freer running rack and longer bearing life. Soft felt seals further enhance bearing life without adding friction.
