Mahle is well-known for making solid engine components, and this piston set for GM LSX 428 cubic inch engines is no exception. If you're building a high-performance LSX engine, these pistons are designed to handle the demands of a serious build. They are specifically made for the LSX platform, ensuring a good fit and reliable operation when you're pushing your engine hard.

This set features a 4.125-inch bore and is designed to work with a 4.000-inch stroke and a 6.125-inch connecting rod. The pistons have a -5.8cc dish, which helps achieve an 11.4:1 compression ratio with a 428cid displacement. They are constructed from 2618 material, a strong aluminum alloy commonly used in performance pistons for its durability and ability to withstand high temperatures and pressures. Each piston weighs in at 450 grams, a balanced weight for performance applications.

When rebuilding your top end, using a well-made piston set like this from Mahle is crucial for engine longevity and performance. Remember 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.
