Wiseco GM L83 Gen V -5cc Dome 3.790in Bore 10.5:1 CR Piston Kit - Set of 8

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston kit is built for serious racers and builders who need parts that can handle severe duty. These pistons are designed to be a no-compromise solution for demanding engine builds, giving you the confidence to push your L83 Gen V engine to its limits.

Each piston in this set is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for handling the high stresses of performance engines. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. To further reduce friction and wear, the pistons are treated with an ArmorGlide skirt coating, which also helps to make operation quieter and more resistant to seizure. The fully machined crown and forced pin oiling are additional details that show these pistons are built for heavy-duty performance.

This kit includes eight pistons, each with a -5cc dome, a 3.790-inch bore, and designed to achieve a 10.5:1 compression ratio. The compression height is 1.292 inches, and the pin diameter is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California.
