Wiseco Chevrolet Small Block 4.185in Bore 18 Deg 1.000 CH +3cc Dome Shelf Piston Kit (Set of 8)

If you're building a high-performance Chevrolet Small Block engine for serious racing or severe duty applications, this set of eight forged pistons from Wiseco is designed to handle the extreme demands. These pistons feature a 4.185-inch bore and a 1.000-inch compression height, with a +3cc dome shelf that can be machined for specific compression ratios. They are built with a 18-degree valve angle in mind, common in many performance cylinder heads.

Wiseco crafts these Professional Series pistons in the USA from 2618 aluminum, chosen for its improved tensile strength under high stress. They come with precision ring grooves, an anti-detonation groove, and features aimed at improving ring seal for better combustion efficiency. The piston crowns are fully machined for accuracy, and they include forced pin oiling to ensure the wrist pins stay well-lubricated. For reduced friction and quieter operation, the skirt is coated with ArmorGlide, which also helps prevent seizure.

This piston kit is intended for heavy to severe duty race builds where durability and performance are paramount. 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.
