Description

When you're pushing your engine to the limit, stock pistons become your weak point. WSM's +.5mm 010 piston assembly delivers OEM-equivalent quality with measurable improvements in heat management and longevity—critical upgrades for sustained high-RPM performance. The MOS2-coated skirts actively reduce friction and draw heat away from critical areas, translating to more power and reliable operation across extended race sessions.

This is a complete piston assembly ready to install, though we recommend having a qualified technician handle the fitment. Order one assembly per cylinder you're rebuilding.
