The GKN Series 21, often called the 934 CV joint, is a crucial component in offroad racing. The Type 172 is a fixed model that accurately represents dimensions like width, OD, bolt pattern, cage diameter, and axle shaft hole. Although non-critical features are approximated, this part is ideal for building mock buggies. It allows the two parts to rotate together while enabling the inner star to move up to 45 degrees out of alignment with the case.
