Wiseco Nissan VQ37VHR 95.5mm Bore Std Oversize 88.39mm Stroke -7cc Vol 9.5:1 - Set of 6

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series forged piston set is built for serious racers and builders who need parts that can handle extreme conditions. These pistons are designed for heavy to severe duty race builds, giving you the confidence to push your engine further.

Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for high-stress engine environments. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown of each piston is fully machined, and they come with forced pin oiling to ensure proper lubrication. Additionally, an ArmorGlide skirt coating is applied to reduce friction, resist seizure, and contribute to quieter operation.

This set includes pistons with a 95.5mm bore and a compression height of 30.74mm, designed to achieve a 9.5:1 compression ratio with a -7cc volume dish. The pin diameter is 0.9055 inches. Please note that these pistons are not CARB approved and cannot be shipped to California.
