Mahle MS Piston Set SBF 431ci 4.080in Bore 4.125in Stroke 6.7in Rod .990 Pin -7cc 11.0 CR Set of 8

This Mahle MS Piston Set is designed for Ford FE engines displacing 431 cubic inches. You get a complete set of eight forged pistons, each weighing 483 grams, ready to be installed in your performance build. These pistons feature a 4.080-inch bore and are designed to work with a 4.125-inch stroke and a 6.700-inch connecting rod. The included 0.990-inch wrist pins are also part of this comprehensive package.

Crafted from 4032 aluminum alloy, these pistons are built for durability and performance under demanding conditions. They feature a dish volume of -7.5cc, which helps achieve an 11.0:1 compression ratio when paired with the appropriate cylinder heads and gasket combination. This compression ratio is a popular choice for naturally aspirated performance builds, offering a good balance between power and pump gas compatibility, though specific tuning will be required to optimize performance and prevent detonation.

This set is intended for engine builders looking to maximize the potential of their Ford FE engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
