Wiseco RED Series Chevrolet Small Block 4.185in Bore 1.425in CH -7.00 CC Piston Set

If you're building a high-performance Chevrolet Small Block engine, Wiseco's RED Series forged pistons are a solid choice. These pistons are designed for demanding applications like drag racing and circle track, offering the strength and durability needed to handle serious power. They are precision-machined in the USA from 2618 aluminum, a material known for its tensile strength, making them well-suited for performance racing and engines with power adders.

Wiseco engineers these pistons with specific features to enhance performance and longevity. The horizontal slot oiling in the pin bores ensures optimal lubrication for the wrist pin and connecting rod small end, which is crucial for long service life under high stress. Each piston features a dedicated forging with a strutted design, maximizing strength while keeping weight down. The included ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall. This set comes complete with premium rings, so you don't need to source them separately, and an accumulator groove helps maintain consistent ring seal and power delivery.

This set is designed for a 4.185-inch bore with a 1.425-inch compression height and a -7.00cc dish volume. 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.
