Wiseco Piston Kit 1999-2006 Harley-Davidson FLHRSI Road King Custom K0208P2

If you're building a high-output engine for your Road King Custom or pushing beyond stock power levels, factory pistons won't cut it. The Wiseco K0208P2 is engineered specifically for forced induction and aggressive cam profiles, delivering the strength and thermal stability needed to handle sustained performance. This is a complete, ready-to-install solution that eliminates guesswork and delivers reliable power gains.

The forged piston crown handles elevated combustion pressures without compromise, while the optimized valve pockets accommodate larger valves and wilder cam timing without interference. You get enhanced lubrication through the force-fed pin oiling system, reduced friction via ArmorGlide® skirt coating, and a pressure seal groove that locks rings in place under load—all working together to maximize efficiency and engine longevity.
