Mahle MS Piston Set GM LSX 430cid 4.135x1.110RCH 4.0 Stk 6.125 Rod .927 Pin -18cc 10.1CR - Set of 8

Mahle is well-known for making solid engine components, and this piston set for GM LSX 430 cubic inch engines is no exception. If you're building or rebuilding a high-performance LSX engine, these pistons are designed to handle the demands of a serious build. They are specifically made for the 4.135-inch bore size and are intended to work with a 4.000-inch stroke crankshaft and a 6.125-inch connecting rod.

This set includes eight pistons, each weighing 433 grams. They feature a -18cc dish volume, which helps achieve a 10.1:1 compression ratio when paired with the right cylinder heads and gasket combination. The pistons utilize a .927-inch pin diameter, a common size for performance applications. The 2618 aluminum alloy construction offers good strength and durability for boosted or naturally aspirated builds. These are a flat-top piston design with a dish, suitable for a variety of LSX engine configurations.

When installing these pistons, remember they are designed for a specific bore size and stroke. It's crucial to ensure your block is machined to the correct 4.135-inch bore and that your crankshaft and connecting rods are the specified lengths for optimal performance and engine longevity. Please note that this piston set is not CARB approved and cannot be shipped to California. Always refer to manufacturer specifications for complete installation details and compatibility.
