Wiseco Opel C20XE 86.25 mm Bore 30.19 mm CH 5.20 CC Piston Set

If you're rebuilding the engine for your Opel C20XE and aiming for serious performance, a strong set of pistons is fundamental. These Wiseco Professional Series pistons are forged from 2618 aluminum right here in the USA, a material chosen for its improved tensile strength, which is crucial when you're pushing an engine hard. They're designed to handle the demands of heavy to severe duty race builds, meaning they're built to last under extreme conditions.

Wiseco has packed these pistons with features that serious builders look for. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which helps maintain compression and prevent blow-by. The crown of each piston is fully machined, and they also come with forced pin oiling to ensure the wrist pins stay well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while also resisting seizure, contributing to a quieter and more durable engine operation.

This set includes four pistons, each with an 86.25 mm bore, a 30.19 mm compression height, and a 0.827-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are a solid option for builders who need reliable, high-performance components for their C20XE engine.
