Wiseco Chevy SB RED Series Piston Set 4135in Bore 1125in Compression Height 0927in Pin - Set of 8

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of performance racing and power adder applications. The RED (Race Engineered Design) series is specifically crafted to offer the strength and durability that high-performance engines require, with precision-machined features that give you a competitive edge. These pistons are a cornerstone for many domestic V8 platforms, finding their way into everything from drag racing machines to circle track contenders.

Wiseco has incorporated several thoughtful details to ensure longevity and performance. Horizontal slot oiling in the pin bores keeps the wrist pin and small-end of the connecting rod properly lubricated, which is crucial for extended service life under stress. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. Additionally, the ArmorGlide skirt coating works to reduce operating friction and noise, while also minimizing wear on the piston skirt and cylinder wall. Each set comes complete with premium rings, so you won't need to source those separately, and an accumulator groove helps maintain consistent ring seal and power output.

This set includes eight pistons, designed for a 4.135-inch bore with a 1.125-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.
