Mahle MS Chevrolet Small Block 396cid 4.170 x 1.062RCH 9.0cc 13.7CR Pistons (Set of 8)

This set includes eight Mahle MS forged pistons, designed for Chevrolet Small Block 396 cubic inch engines. These pistons are built to handle the demands of a high-performance engine build, featuring a 4.170-inch bore and a 3.625-inch stroke. The 1.062RCH (dish volume) contributes to a 13.7:1 compression ratio when paired with a 9.0cc combustion chamber, making them suitable for aggressive engine builds where maximum power is the goal.

Crafted from 2618 aluminum alloy, these pistons are known for their strength and durability under high temperatures and pressures. The 0.927-inch wrist pin diameter is standard for many performance applications, and the 6.125-inch rod length is a common pairing. Each piston weighs 458 grams, providing a balanced rotating assembly. Mahle's MS series pistons are a popular choice for engine builders looking for reliable forged components that can withstand significant abuse.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Ensure you consult with your engine builder or refer to Mahle's technical documentation for specific installation requirements and compatibility with other engine components, such as cylinder heads and crankshafts, to achieve the desired compression ratio and performance.
