Wiseco Chevy LT1 4.070in Bore 1.299in CH -12.00 CC Piston Set

If you're rebuilding the heart of your Chevy LT1 engine for serious racing or heavy-duty performance, a strong set of pistons is crucial. Wiseco's Professional Series pistons are built from the ground up for those demanding applications. They're forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to handle the extreme pressures of racing.

These aren't just basic pistons; they're packed with features for durability and performance. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is key for compression and power. They also come with an ArmorGlide skirt coating that helps reduce friction and resist seizure, all while keeping operation quieter. The fully machined crown and forced pin oiling further contribute to their ability to withstand heavy to severe duty use.

This set is designed for an 8-cylinder engine, with a 4.070-inch bore and a -12.00cc dish volume, giving you a specific compression ratio target. Remember, these pistons are not CARB approved and cannot be shipped to California. For a robust rebuild that can handle the stress of racing, this Wiseco set is a solid option.
