Wiseco Piston Kit 3.875 in. Bore 10.5:1 Compression Ratio Harley-Davidson Twin Cam 103 2011-2016 K2792

If you're pushing your Twin Cam 103 hard—whether on the dyno, the track, or the street—stock pistons will eventually let you down. The Wiseco K2792 kit gives you forged pistons with ArmorGlide™ skirts and ArmorPlating ring grooves, engineered to handle sustained high-RPM loads while maintaining ring seal under detonation. Complete with rings, pins, and retainers, this is a bolt-in rebuild that maximizes both power output and engine longevity.

Wiseco's U.S.A. manufacturing ensures tight tolerances and consistent quality across every unit. You're getting a piston kit built for serious performance, not a compromise.
