Wiseco Chevy SB RED Series Piston Set 4135in Bore 1000in Compression Height 0927in Pin - Set of 8

If you're building a high-performance Chevrolet Small Block engine, especially for demanding applications like drag racing or circle track, you need pistons that can handle the stress. Wiseco's RED Series pistons are forged from 2618 aluminum, a material chosen for its tensile strength, making them well-suited for the high loads and temperatures found in performance racing and power adder setups.

These pistons feature Race Engineered Design (RED) principles, meaning they're specifically shaped for optimal performance. They have horizontal slot oiling in the pin bores to ensure the wrist pin and connecting rod small end stay well-lubricated, which is crucial 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 skirt and cylinder wall. 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 output.

This set is for an 8-cylinder engine with a 4.135-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.
