Description

KB Series Hypereutectic 390 Alloy with 16% Silicon Pistons are T-6 heat treated and feature fully machined heads and valve reliefs. Designed for high-performance marine, drag race, circle track, street, or towing applications, they offer lower conductivity and a reflective piston top to reduce oil temperatures and combustion heat. Wrist pins and spiral lock rings are included, but piston rings are not.
