Wiseco Chevy SB RED Series Piston Set 4185in Bore 1000in Compression Height 0927in Pin - Set of 8

If you're building a high-performance Chevrolet Small Block engine for racing or serious street use, a strong set of pistons is fundamental. This Wiseco RED Series piston set is built to handle the demands of power adder applications and intense racing environments like drag strips and circle tracks.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its tensile strength, which is crucial for engines that see high RPMs and significant stress. Wiseco's Race Engineered Design (RED) process means these pistons have specific features to give you an edge. For instance, the horizontal slot oiling in the pin bores ensures the wrist pin and small end of the connecting rod stay well-lubricated, which is vital for longevity. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a low weight. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls. Each set comes complete with premium rings, so you don't have to source them separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

This set includes eight pistons, each with a 4.185-inch bore, 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.
