Description
The Peterson Fluid Guide Washer keeps your splined pulley system running true, preventing lateral movement that can cause premature wear on your serpentine belt and accessory drive components. Precision-engineered for Peterson’s spline drive pulley lineup, this press-fit washer is a critical maintenance item that protects your entire front-end accessory drive (FEAD) system from damage. If you’re running a high-RPM engine or forced induction setup, proper pulley alignment is non-negotiable—this washer ensures it.
