Wiseco Chevrolet LT1 6.2L 4.065 Bore 1.304 Comp Ht. 3.622 Stroke 6.125 Rod -12 Volume 10.5 CR

If you're rebuilding the heart of your Chevrolet LT1 6.2L engine for serious racing or heavy-duty performance, Wiseco's Professional Series forged pistons are a solid choice. These aren't your average pistons; they're built from the ground up with features aimed at handling extreme conditions and delivering consistent power when you need it most. They are designed to work with a 4.065 inch bore, a 1.304 inch compression height, and a 3.622 inch stroke, aiming for a 10.5:1 compression ratio with a -12cc dish volume.

Wiseco forges these pistons in the USA from 2618 aluminum, a material known for its improved tensile strength, which is crucial for handling the high pressures and temperatures found in race engines. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal and prevent detonation. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated under extreme loads.

This set includes eight pistons, ready for your performance build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a build demanding the best in durability and performance, these Wiseco pistons are a well-built option.
