Wiseco Chevy LS1/LS2 RED Series Piston Set 3780in Bore 1299in Compression Height - Set of 8

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of high-performance Chevy LS1 and LS2 engines. The RED (Race Engineered Design) series is all about providing the strength and durability needed for racing and power adder applications, while also incorporating precision features that give you a competitive edge. Whether you're building for drag racing, circle track, or just want a rock-solid foundation for a serious street build, these pistons are a popular choice for domestic V8 platforms.

Wiseco machines these pistons with a focus on maximizing strength-to-weight. You'll find horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pins and small-end of the connecting rods properly lubricated, leading to longer service life. They also feature an accumulator groove, designed to help maintain consistent ring seal and ensure you're getting all the power your engine can make. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls.

This set includes eight pistons, each with a 3.780-inch bore and a 1.299-inch compression height, along with a 0.927-inch pin diameter. Wiseco includes premium rings with this set, so you won't need to source those separately. Just a heads-up, these pistons are not CARB approved and cannot be shipped to California.
