Wiseco Chevy LT1 Piston Set - 4.075in. Bore - 1.115 in. Comp. Height - 0.927in. Pin Diameter - 8pc

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing. The 4.075 inch bore size is specific to certain Chevrolet LT1 engine builds, and the 1.115 inch compression height combined with a 0.927 inch pin diameter are critical measurements for proper piston-to-valve clearance and deck height in your performance engine.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure robust performance under heavy load. The ArmorGlide skirt coating helps reduce friction and noise while also resisting seizure, which is crucial for engines pushed to their limits. The fully machined crown and forced pin oiling further contribute to their durability in severe duty applications.

This set includes eight pistons, designed to be a direct replacement for your Chevy LT1 engine's original components, but with significantly improved strength and performance characteristics. Remember that these pistons are not CARB approved and cannot be shipped to California.
