Allstar Accessory Pulley Spacers

Allstar offers pulley shims for your crankshaft and water pump to stop throwing accessory belts. If your accessory pulleys aren't centered on each other you can cause extreme belt wear and increase the amount of horsepower it takes to drive your pulleys. If the situation is extreme you can even lose a belt when you have major changes in engine RPM. Nothing can reduce the life of your engine or bring your race to an end faster than not spinning your water pump. Take the extra few minutes to make sure you have your accessories all straightened out.
