The OTII metallic clutch provides an excellent combination of light weight, strength and price. Capable of handling the highest horsepower cars, it can also be set up to be gentle on smaller engines. It is important not to utilize a diaphragm spring stronger than necessary. We recommend a GREEN spring for Sprite, Midget and other small engines, a BUFF spring for Formula Ford, and ORANGE for F2000 and Formula Atlantic. Most larger engines will utilize a GREY or DOUBLE GREY spring. PLEASE NOTE THAT CLUTCHES DO NOT INCLUDE DRIVEN DISCS.
