Wiseco Chevy SB RED Series Piston Set 4165in Bore 1215in Compression Height 0927in Pin - Set of 8

If you're building a high-performance Chevrolet Small Block engine, this Wiseco RED Series piston set is designed to handle the demands of racing and power adder applications. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see extreme stress from drag racing, circle track, or forced induction setups. The Race Engineered Design (RED) process means these pistons are specifically optimized for their intended engine application, balancing strength with a manageable weight.

Wiseco has included several features to ensure longevity and performance. The horizontal slot oiling in the pin bores keeps the wrist pin and connecting rod small end well-lubricated, which is vital for preventing premature wear. An accumulator groove is also part of the design, helping to maintain consistent ring seal under pressure, which translates to better power delivery and efficiency. To further reduce friction and noise, these pistons come with an ArmorGlide skirt coating, which also helps minimize wear on the cylinder walls and the piston skirts themselves. This set includes premium rings, so you won't need to source those separately.

It's important to 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 when working with performance engine components.
