Wiseco RED Series Chevy LS 4.170in Bore 1.294in CH -15.00 CC Piston Set

Wiseco is well-known for its high-performance forged pistons, and their RED Series takes that reputation a step further. These pistons are built using Race Engineered Design, meaning they're crafted with the strength and durability that performance engines demand, along with precision features that give you an edge. They're available for many popular V8 engines, which are the backbone of racing from drag strips to circle tracks. This specific set is designed for Chevrolet LS engines with a 4.170-inch bore.

Each piston in this set is forged and machined in the USA from 2618 aluminum, chosen for its tensile strength, making them ideal for high-stress racing and applications with power adders. To ensure optimal lubrication and a long service life, they feature horizontal slot oiling in the pin bores. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. You'll also find an accumulator groove to help maintain consistent ring seal and power delivery. Plus, the ArmorGlide skirt coating works to reduce friction and noise, while also minimizing wear on the skirts and cylinder walls.

This set includes premium rings, so you won't need to source those separately. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
