Wiseco Chevy SB RED Series Piston Set 4130in Bore 1000in Compression Height 0927in Pin - Set of 8

Wiseco is well-known for making strong, reliable internal engine components for performance applications. This RED Series piston set is built for Chevy Small Block engines and uses Race Engineered Design (RED) principles to give you the strength and durability needed for demanding racing and power adder setups. They are forged and machined right here in the USA from 2618 aluminum, a material chosen for its high tensile strength, making these pistons well-suited for the stresses of competition.

You'll find some smart features designed to help your engine run better and last longer. The horizontal slot oiling in the wrist pin bores is key for keeping the wrist pin and the small end of the connecting rod properly lubricated, which is critical for service life. Wiseco also uses dedicated forgings for each specific engine application, allowing them to create an optimized strutted design that maximizes strength while keeping weight down. To further reduce friction and wear, these pistons come with an ArmorGlide skirt coating, which also helps quiet down operation. Plus, each set includes premium rings, so you won't have to hunt for compatible ones separately. An accumulator groove is also included to help maintain consistent ring seal and power output.

This set is designed for a 4.130 inch bore with a 1.000 inch compression height and a 0.927 inch pin diameter. Please note 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.
