Mahle MS Piston Set LS7 430cid 4.135in Bore 4.000in Stroke 6.067in Rod .927in Pin -2.5cc 11.8 CR

If you're rebuilding the heart of your LS7 engine, especially for a 430 cubic inch displacement, a solid set of pistons is crucial. This Mahle MS Piston Set is built for that kind of performance-oriented build, designed to handle the demands of a high-output naturally aspirated or boosted LS7.

Mahle uses 4032 aluminum for these pistons, which is a well-known material for its strength and ability to handle thermal expansion. This means you get a well-built piston that's less prone to seizing in the cylinder bore, especially important when you're pushing the limits. The pistons have a -2.5cc dish volume and a 4.000-inch stroke compatibility, contributing to an 11.8:1 compression ratio when paired with LS7 style heads. This compression level is ideal for maximizing power output in many performance applications. They come with a .927-inch pin diameter, a standard size for many performance connecting rods, and a 6.067-inch rod length compatibility. Each piston weighs in at 452 grams, keeping rotating mass manageable for better engine response.

This set is specifically for the LS7 7.0L engine and is designed to work with LS7 style heads. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, ensure you have the correct connecting rods and crankshaft to match the stroke and rod length specifications.
