Mahle MS Piston Set SBC 383ci 4.03in Bore 3.75in Stroke 6.0in Rod .927 Pin 6cc 12.0 CR Set of 8

Mahle is a well-known name in engine components, particularly for their piston technology. This Mahle MS Piston Set is built for performance Small Block Chevrolet (SBC) engines, specifically for a 383 cubic inch displacement. If you're rebuilding a performance SBC, these pistons are designed to handle the demands of a high-output engine.

These pistons feature a 4.030-inch bore and a 3.75-inch stroke, creating that 383ci displacement. They have a 6cc dish volume and a 12.0 compression ratio when paired with a 6.0-inch connecting rod and a typical SBC head chamber. The .927-inch pin diameter is standard for many performance applications. They are constructed from 2618 aluminum, a strong and lightweight material commonly used in forged pistons for its durability under high stress and temperature. Each piston weighs approximately 463 grams, contributing to a well-balanced rotating assembly.

This set includes eight pistons, ready to be installed in your SBC 383ci build. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or refer to Mahle's installation guidelines for specific details regarding piston-to-wall clearance, ring gap, and assembly procedures to ensure optimal performance and longevity.
