Wiseco GM L83 Gen V -5cc Dome 3.780in Bore 10.5:1 CR Piston Kit - Set of 8

If you're building a serious performance engine for your GM L83 Gen V, this Wiseco forged piston kit is designed to handle the extreme demands of racing. These aren't your average pistons; they're built from the ground up for heavy to severe duty applications where reliability under stress is paramount. Wiseco has engineered these pistons from 2618 aluminum, a material known for its improved tensile strength, making them a solid choice for high-performance builds.

Each piston in this set features a -5cc dome to achieve a 10.5:1 compression ratio, which is a popular target for many performance builds looking for a good balance of power and pump gas compatibility. You'll find precision ring grooves, an anti-detonation groove, and features designed for additional ring seal, all contributing to better combustion control and durability. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated under high loads. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, a practical benefit for both performance and longevity.

This kit includes a set of 8 pistons, ready to be installed in your L83 Gen V engine. Remember that these pistons are manufactured in the USA, reflecting a commitment to quality construction. Please note that this part is not CARB approved and cannot be shipped to California.
