1297368007 Release Fork, compatible with ZF 12-speed and 16-speed manual and AMT gearboxes. Made of high-strength cast steel through integral forming, it features excellent wear resistance and impact resistance, and is not easy to deform or break under force. The surface is hardened to reduce friction loss and ensure smooth and accurate gear shifting. Its dimensions strictly conform to original factory standards for tight installation and stable torque transmission, effectively preventing gear shifting jamming and jumping. High temperature and fatigue resistant, it adapts to long-term heavy-duty operation of heavy trucks and coaches and extends service life.
