Mahle MS Piston Set SBC 383ci 4.03in Bore 3.75in Stk 6.125in Rod .927in Pin -4cc 11.2 CR Set of 8

Mahle is well-known for making solid engine components, and this piston set is a great example of their work for performance builds. If you're putting together a 383 cubic inch Small Block Chevrolet engine, these pistons are designed to handle the demands of a performance application. They feature a 4.030 inch bore and are designed to work with a 3.750 inch stroke crankshaft and a 6.125 inch connecting rod, giving you a displacement of 383 cubic inches.

These are forged pistons, which means they are made from a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast ones, making them ideal for engines that will see higher RPMs and increased cylinder pressures. The -4cc valve relief dish helps achieve a 11.2:1 compression ratio with the right cylinder head, offering a notable bump in power over stock configurations. The wrist pin diameter is .927 inches, a common size for performance applications.

This set includes eight pistons, enough for a complete V8 engine. Please note that these pistons are not CARB approved and cannot be shipped to California. They are also subject to California's Prop 65 warning. Ensure you have the correct cylinder heads and a compatible rotating assembly to achieve the intended compression ratio and displacement.
