Rubber bushings allow too much uncontrolled lateral movement in a suspension and provide mushy handling.
Polyurethane bushings allow less lateral movement, but create an unwanted friction spike during rotational movement. This causes a squeaking noise…a huge distraction on any street car, and an indication of uncontrolled suspension friction on a race car.
Heim ends can get loose and rattle and are susceptible to dirt and wear.
Regular Delrin is a huge step forward for a rotational bushing, but still needs lubrication to work properly and will accommodate only a small amount of articulation.
The new RideTech R Joint combines the best qualities of low friction movement, lateral stability, full range articulation, and quiet operation into one special bearing that is as home on the street as it is on the racetrack!
