Wiseco Chevy LSX Junkyard Dog 5.3L .945in Pin 3.800 Bore NA/Boost/Nitrous Drop In Replacement Piston

Wiseco's Professional Series pistons are built for serious LSX engine builds, offering a robust solution for naturally aspirated, boosted, or nitrous applications. These pistons are designed as a drop-in replacement for Chevy 5.3L LS engines, aiming to remove limitations for racers and builders tackling heavy to severe duty performance projects. They are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for handling the stresses of high-performance engines.

You'll find precision ring grooves, an anti-detonation groove, and features designed for additional ring seal, all contributing to better combustion control and durability. The pistons also come with an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure. The fully machined crown and forced pin oiling further enhance their capability for demanding use. This set is engineered to withstand the rigors of racing and severe duty, making them a solid choice for those pushing their LSX engines to the limit.

This set includes eight pistons, each with a 3.800-inch bore and a 0.945-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
