Lightweight billet steel duplex timing gear set. It has a unique crank gear that has several keyways so it can be easily adjusted in two degree increments, which enables precise cam timing to compensate for reground cams or to dial in maximum power. We fit these sets in our shop and find that they give a tight and precise chain fit. Supplied with low-stretch German-manufactured Iwis timing chain.
For even finer timing adjustment, add a 1 degree offset timing key SEN0051A, sold separately.
