Product Details

Mahle's MS forged piston set is built for Chevrolet Small Block engines displacing 395 cubic inches. These pistons are designed for high-performance applications where strength and reliability are paramount. Each piston in this set of eight features a 4.165-inch bore and a 1.062-inch compression height, working with a 3.625-inch stroke and a 6.125-inch connecting rod to achieve a specific compression ratio.

Crafted from 2618 aluminum, a material known for its excellent strength-to-weight ratio and resistance to fatigue under extreme conditions, these pistons are well-suited for demanding builds. The 9.0cc valve relief volume is designed to provide adequate clearance for most performance camshaft profiles, and the 0.927-inch wrist pin provides a solid connection to the connecting rod. With a calculated compression ratio of 13.7:1, these pistons are intended for engines that require a higher compression for improved power output, often paired with specific cylinder heads and camshafts to optimize performance. Each piston weighs approximately 456 grams, contributing to a balanced rotating assembly.

This set includes all eight pistons needed for a complete engine rebuild. Please note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified professional for specific application advice and installation procedures.
