Mahle MS Piston Set SBC 359ci 4.040in Bore 3.5in Stroke 5.7in Rod .927 Pin -8cc 12.1 CR Set of 8

Forged from 2618 aluminum, this Mahle MS piston set is built for serious performance in a 359 cubic inch Small Block Chevrolet engine. The 4.040-inch bore size is a common starting point for many performance builds, and the -8cc dish volume combined with a 3.5-inch stroke and 5.7-inch rod length helps achieve a 12.1:1 compression ratio, ideal for naturally aspirated or forced induction applications where pump gas is used.

These pistons are designed with a 1.550-inch compression height and utilize a standard 0.927-inch wrist pin, making them compatible with a wide range of connecting rods and crankshafts commonly found in performance Small Block Chevy builds. The 2618 aluminum alloy offers excellent strength and durability under high temperatures and pressures, while the forged construction resists deformation better than cast pistons. Each piston weighs in at approximately 464 grams, contributing to a well-balanced rotating assembly.

This set includes eight pistons, ready for your next 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.
