Rollmaster Gold Timing Sets normally feature Nitride hardened cam and crank gears and include a one-piece Torrington bearing or a brass thrust washer with an IWIS chain. Gold Timing Chain sets have 9 keyway crank gears, unless otherwise stated, which allow camshaft timing adjustments in increments of 1°. Rollmaster Timing Sets are light weight and stronger than any other timing set available, due to the weight savings of billet steel and use of advanced CNC machinery.
