ARC #6522HD Heavy Duty .490" x 2.075" Wrist Pin for Extended Strokers

• Extended 2.075" length for deeper rod bores.
• .490" diameter matches standard pistons.
• HD construction fights deflection.

The ARC #6522HD wrist pin extends support in long-stroker setups, stabilizing the piston crown under max compression. This leads to cleaner combustion and freer breathing at high revs.

For kart racers in open classes, it unlocks potential by allowing bigger bores without compromise. Its length reduces bind, smoothing the path to top speeds.

Heavy duty means surviving crashes and heat cycles intact. Integrate with C-clip retainers for foolproof retention.
