If more than two joints are used in a steering system, a support bearing must be used to prevent "looping" and binding. Use of a vibration reducer and two u-joints will also call for a support bearing to be used. A system with a double u-joint and a single u-joint has three flex points and will require a support bearing. Support bearings will work with all 3/4" splined or Double D steering shafts. All billet supports accommodate a 3/4" shaft. Our standard supports are 2-1/2" tall with two 5/16"-18 threaded holes in the end for mounting and are available in steel, aluminum, polished aluminum, stainless steel, and polished stainless steel. The 6" cut and weld billet support is available only in steel and can be cut at any angle for a perfect fit.
