Chevy SBC 350 BBC 454 Bronze 0.500" Shaft Distributor Gear

These bronze distributor gears from Speedmaster are recommended for steel billet mechanical roller tappet cams and slot hard-faced steel billet mechanical flat tappet cams. Bronze gears absorb the increased wear in special cams and magnetos and are easily replaced before costly damage to the camshaft gear occurs. The gears are precision-machined from the highest quality aluminum silicon bronze alloy for maximum durability. Bronze distributor gears must be checked often and replaced as needed.
