Description
If you’re running a dedicated race engine or high-performance build, a quality crankshaft mandrel cap is non-negotiable—it secures critical rotating components and prevents fluid loss under extreme conditions. The Peterson Fluid Drive Washer eliminates guesswork with precision engineering, black anodized aluminum construction, and a proven hex nut design that stays tight through thousands of track miles. This is the kind of part that separates reliable builds from ones that leave you stranded.
