Wiseco RED Series Chevy LS 4.155in Bore 1.294in CH -15.00 CC Piston Set

When you're rebuilding the top end of a high-performance Chevy LS engine, especially for demanding applications like drag racing or circle track, you need pistons that can handle serious abuse. The Wiseco RED Series pistons are built for exactly that kind of work. They utilize Race Engineered Design principles to give you the strength and durability needed for performance racing and power adder setups.

These pistons are forged and machined right here in the USA from 2618 aluminum, a material chosen for its high tensile strength. Wiseco has incorporated several thoughtful features to ensure longevity and performance. You'll find horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pin and small-end of the connecting rod properly lubricated under high stress. The dedicated forgings allow for an engine-specific strutted design, meaning Wiseco optimizes the strength-to-weight ratio for your LS engine. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall.

This set includes premium rings, so you won't have to hunt for compatible ones separately. An accumulator groove is also included, which helps maintain consistent ring seal and, by extension, consistent power delivery. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
