Mini Duplex chain and vernier adjustable steel gear set
S12- DUPLEX CHAIN AND VERNIER ADJUSTABLE STEEL GEAR SET
If you want to get the maximum benefit from a "hot" cam it is doubly important that the cam timing be correct. This adjustable timing gear set uses sets of dowel holes with two degree increments. When done properly your cam will be within one degree of right. (Use a 1 degree offset key and you can be exact!) Kit includes billet steel upper and lower gears plus a quality chain.
