Wiseco Chevy SB RED Series Piston Set 4135in Bore 1062in Compression Height 0927in Pin - Set of 8

Wiseco is well-known for making strong, reliable engine components for performance applications. This RED Series piston set is built for Chevy Small Block engines, designed to handle the demands of racing and power adder setups. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard.

The RED Series name stands for Race Engineered Design, and you can see that focus in the details. Each piston features horizontal slot oiling in the pin bores to ensure the wrist pin and connecting rod small end stay well-lubricated, which is key for long service life under stress. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a manageable weight. To further reduce friction and wear, the pistons come with an ArmorGlide skirt coating, helping to quiet operation and protect the cylinder walls. You also get premium rings included with each set, so you don't have to source them separately, and an accumulator groove helps maintain consistent ring seal for reliable power delivery.

This set includes eight pistons, each with a 4.135-inch bore, a 1.062-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.
