Tilton’s 7.25″ OT-II metallic racing clutches offer the low moment-of-inertia, high torque capacity and reliability necessary for the most demanding racing applications.
Tilton has upgraded their popular line of 5.5″ OT-III metallic racing clutches with the addition of lower rate diaphragm spring options. While still providing high torque capacity, the new diaphragm springs significantly reduce release loads compared to other 5.5″ racing clutches on the market. The lower release loads put less stress on engine crankshaft thrust bearings, making these clutches ideal for smaller 4-cylinder and 6-cylinder engines. In addition, a lower release load on the clutch equates to less pedal effort for the driver, allowing for easy shifting. Spring options now include White (W), Orange (ORA) and Gray (G). 5.5″ OT-III metallic racing clutches are available in 1, 2, 3 and 4-plate configurations.
