Racetech Universal Joints

At Raceparts UK Ltd we supply a wide variety of different Racetech Universal Joints for different applications. This page will help you select the right Universal Joint (UJ) for your application. Often people when designing cars make the wrong choice of UJ. This will mean that either you are using something heavier and more costly then it needs to be or you are using a part which is not up to the job. UJ's are often used on critical systems of the car such as steering or gear linkage. If you get this wrong then it will cause an accident.

Saddle washers are also available for these UJ's (please see below).
