Description:
Get the right racing ratio with Allstar small block Chevy reduction pulleys. Stock pulleys do not provide the correct ratio for racing, where engine rpm is much different than it is for street applications. Allstar aluminum pulleys are specifically made for racing and are smaller in diameter. Enhance your acceleration capabilities with Allstar SBC reduction pulleys.
