Description

The KB Series Hypereutectic 390 Alloy Pistons with 16% Silicon are engineered for superior performance in Ford Small Block 302 engines. These T-6 heat-treated pistons feature advanced machining, providing benefits like lower conductivity and a reflective piston top that reduce oil temperatures and minimize heat/pressure loss from combustion.

Ideal for high-performance, marine, drag, circle track, and towing applications, these pistons incorporate features such as CNC machined pin bores, diamond-finished skirts, machined-in oil returns, and an accumulator groove for improved compression ring seal. Mini grooves further protect against scuffing during extreme heat.

Each set includes eight pistons, lock rings, and pins at no additional cost. The fully machined head and valve reliefs ensure a precise fit. These pistons are a durable and reliable choice for enthusiasts seeking to maximize their Ford 302 engine's potential.
