Wiseco Chevrolet LT1 6.2L 4.075 Bore 1.304 Comp Ht. 3.622 Stroke 6.125 Rod -12 Volume 10.5 CR

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds in Chevrolet LT1 6.2L engines. The material choice here is key; 2618 aluminum offers improved tensile strength, which is crucial when dealing with the extreme pressures and heat generated in high-performance applications. This set is designed to handle severe duty, meaning they're ready for the kind of stress that pushes engines to their limits.

Wiseco has included several features to ensure these pistons perform reliably under pressure. You'll find precision machined ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. This attention to detail helps maintain compression and prevent detonation, both vital for power and engine longevity. The piston crowns are also fully machined, and the design incorporates forced pin oiling to keep the wrist pins properly lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and contribute to quieter operation, which is a notable benefit when building a high-performance engine.

This set includes eight pistons, each with a 4.075-inch bore, a 1.304-inch compression height, and a 3.622-inch stroke compatibility with a 6.125-inch rod. The volume is -12cc, resulting in a 10.5:1 compression ratio. Please note that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in their LT1 6.2L engine, this Wiseco Professional Series piston set is a well-built option.
