Product Details

If you're building a high-performance Ford 445ci engine, a solid set of pistons is where you start. This Mahle MS Piston Set is designed for those serious about getting the most out of their SBF (Small Block Ford) platform, specifically for the 445 cubic inch displacement. These aren't your average pistons; they're forged from 4032 aluminum, a material known for its strength and durability under high stress, making them a great choice for boosted or high-compression builds.

This set features a 4.080-inch bore and is designed to work with a 4.250-inch stroke crankshaft and a 6.700-inch connecting rod, with a standard 0.990-inch pin. The -28cc dish volume, combined with other engine components, results in a 9.3:1 compression ratio, which is a popular target for streetable performance builds that can still handle a good amount of boost or nitrous. At 495 grams each, they offer a good balance of strength and weight for their size. Mahle is a well-known name in engine components, and this set reflects their commitment to well-built parts for demanding applications.

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.
