Wiseco Chevy XLS F.T. 1.250inch (6415LB3RB3) Piston Shelf Stock Kit

If you're rebuilding a high-performance Chevrolet Small Block engine for serious racing or heavy-duty use, this Wiseco Professional Series piston kit is built to handle the stress. These aren't your average pistons; they're forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under extreme conditions. This kit is designed for applications that demand robust performance and durability, fitting a wide range of Chevrolet vehicles from classic Bel Air models to later C1500 pickups.

Wiseco packed these pistons with features to ensure they perform when you need them most. The crown is fully machined, and the precision ring grooves are designed for optimal sealing, including anti-detonation grooves. They also feature forced pin oiling to keep the wrist pins lubricated, and the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure. These pistons are built to withstand heavy to severe duty performance applications, making them a solid choice for builders who push their engines hard.

This kit includes a set of eight pistons, ready for your next engine build. 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.
