Mahle MS Piston Set Chevrolet 357ci 4.030in Bore 3.50stk 5.7in Rod .927 Pin -3.0cc - Set of 8

Mahle is a well-known name in engine components, especially for their piston technology. This MS Piston Set is built for Chevrolet Small Block engines, specifically for builds aiming for 357 cubic inches with a 4.030-inch bore and a 3.500-inch stroke. These pistons are designed to work with a 5.700-inch rod and feature a 0.927-inch pin, making them a solid choice for serious engine work.

These pistons are forged from 4032 aluminum, a material chosen for its strength and durability under high stress. The -3.0cc dish volume contributes to a compression ratio of 10.7:1 with the specified components, which is ideal for many performance applications. They are designed for a press-fit pin installation, a common method for performance engines that ensures a secure connection between the piston and the connecting rod. Each piston weighs in at 475 grams, contributing to a balanced rotating assembly.

This set includes eight pistons, enough for a complete V8 engine. They are built to meet the USRA Factory Stock Rules, indicating they are suitable for specific racing classes where compliance is key. Please note that these pistons are not CARB approved and cannot be shipped to California. Ensure you check all local regulations before purchasing.
