We have now have light weight water pump pulleys for every model 4AG! If you have the 16V, 20V, FWD, or RWD, we've got you covered. We have these in red,  silver, gold or blue.

They weigh in at nearly 50% lighter than the factory pulleys. Our water pump pulleys are 18% larger than factory to help prevent cavitition at high RPM's. This helps the engine run cooler at high RPM's.

These are perfectly balanced, and we've tested them on cars running up to 11,000 RPMS!

Please select the pulley you need from the list carefully. Let us know if you have any questions!




  • Balanced for use at high RPM's
