Mahle MS Piston Set SBF 428ci 4.125in Bore 4.000in Stroke 6.25in Rod .927 Pin -6.5cc 12.1CR Set of 8

Mahle is a well-known name in engine components, recognized for their expertise in piston technology. This Mahle MS Piston Set is built for the Ford Small Block 428 cubic inch engine, a classic choice for performance builds. If you're assembling or rebuilding a high-performance 428ci engine, these pistons are designed to handle the demands of increased power and stress.

These pistons are forged from 2618 aluminum, a strong material chosen for its durability under high temperatures and pressures. They feature a 4.125-inch bore and are designed to work with a 4.000-inch stroke crankshaft and a 6.250-inch connecting rod. The pin diameter is 0.927 inches. With a -6.5cc dish volume, these pistons contribute to a 12.1:1 compression ratio when used with appropriate cylinder heads and gasket combinations, making them suitable for naturally aspirated or forced induction applications where significant power is the goal. Each piston weighs approximately 448 grams, contributing to a balanced rotating assembly.

This set includes eight pistons, ready for your engine build. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always recommended to consult your engine builder or a professional mechanic for specific assembly details and compatibility with other engine components to ensure optimal performance and longevity.
