.490" OD Piston Pin for Raptor and Flathead Engines

The .490" outer diameter piston pin (SKU 555509) is the unsung hero connecting piston to rod in Raptor flathead setups. Its robust construction handles reciprocating stresses, allowing fluid motion that keeps energy flowing to the wheels.

In kart racing, where split-second shifts matter, a reliable pin means no wobbles or slaps that disrupt rhythm. It pivots seamlessly, minimizing energy loss so more of your engine's grunt propels you forward.

• Precision-ground for exact fit, compatible with standard Raptor and flathead pistons.
• Heat-treated for superior wear resistance against constant impacts.
• Supports higher RPM tolerances, ideal for tuned engines chasing top speeds.

During assembly, clip it in with confidence—it's designed for quick servicing, getting you back on track faster. Racers report smoother idles and crisper revs post-install, attributes that compound into better qualifying times. This pin fortifies your bottom end, enabling aggressive driving without fear of mechanical surrender.
