TIMING SET CHEV SB STEEL ROLLER 9 key w/shim

Rollmaster's Red Label timing sets are produced using light weight billet steel for both the crank and camshaft sprockets. These sets come with a 9 keyway crankshaft sprocket in 2 degree increments, the relationship from crank keyway to camshaft sprocket timing is 2:1 meaning that the amount of advance or retard at the camshaft is in one degree increments. Multi keyways are solid fixture and do not tend to move or work lose like offset dowles, thus providing a positive locking of the cam timing to what ever posirtion is desired. No additional maching is required to fit these sets or the need for offset bushings or drilling of cam gears. All Red Label timing sets come with Rollmasters own premium grade full roller timing chain. Every small and big block Chev set comes standard with a brass thrust washer and is available with an optional one piece Torrington thrust bearing (ROCS1040).
