Wiseco VOLKSWAGEN 1.8 LTR 1.320 Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components, especially for performance applications. If you're rebuilding the engine in your 1984-1992 Volkswagen Jetta, particularly for demanding use, their Professional Series forged pistons are a solid choice. These aren't just standard pistons; they're built from the ground up for serious racers and builders who need reliability under extreme conditions.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for handling high pressures and temperatures. You'll find precision ring grooves, anti-detonation features, and extra ring seal enhancements designed to keep things running smoothly and prevent issues. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, which is a nice touch for a performance part. The fully machined crown and forced pin oiling further contribute to their ability to handle heavy to severe duty performance builds.

This kit includes a set of four pistons, each with an 83.00 mm bore and a 33.50 mm compression height, designed for the 1.8L 8V European engine configuration. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For a robust engine build that can take a beating, these Wiseco pistons are a well-built option.
