Mahle MS Pistons Ford 428 cid 4.125in Bore 4.0 Stroke 6.250 Rod 0.927 Pin -26cc 9.9 CR Set of 8

If you're building or rebuilding a Ford 428 cubic inch engine, these Mahle MS pistons are a solid choice for serious performance. Mahle is a well-known name in engine components, and this set is designed for engines that demand more than stock. They are forged from 2618 aluminum, a material chosen for its strength and ability to handle high temperatures and pressures, making them suitable for performance applications where stock cast pistons might fail.

This set is engineered for a 4.125-inch bore and a 4.0-inch stroke, with a 6.250-inch rod length. The pistons feature a -26cc dish volume, which, combined with the other specifications, results in a 9.9:1 compression ratio. This compression ratio is a good balance for many performance builds, offering improved power output without being overly sensitive to fuel octane. The 0.927-inch pin size is standard for many performance applications. These pistons also come with a TBC coating on the crown, which helps with thermal management and can reduce friction.

Each piston weighs approximately 448 grams, which is typical for forged aluminum pistons and helps with engine balance. 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. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
