Wiseco Opel C20LET 86.5mm Bore / -13cc dish -/ 8:1 CR Piston Kit

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance applications where durability is key. The 86.5mm bore size and -13cc dish contribute to an 8:1 compression ratio, making them suitable for boosted engines that demand robust internal components. Wiseco engineers these pistons in the USA, ensuring that each one meets strict standards for strength and reliability.

You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal and prevent detonation, which is critical in high-stress engine builds. The ArmorGlide skirt coating is applied to reduce friction and resist seizure, helping to keep the engine running smoothly and quietly even under severe duty. The fully machined crown and forced pin oiling further contribute to the overall longevity and performance of these pistons.

This kit includes four pistons, each with a 30.49mm compression height and a 0.827-inch pin diameter, designed to fit Opel C20LET engines. While these pistons are built for heavy to severe duty race applications, please note they are not CARB approved and cannot be shipped to California. If you're building a high-performance C20LET engine, these Wiseco pistons offer a well-built foundation.
