Wiseco Chevy LT1 4.075in Bore 1.299in CH -12.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is a prime example, built for serious racers and builders who need parts that can handle heavy to severe duty use. If you're putting together a high-performance LT1 engine, these pistons are designed to be a solid foundation.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding conditions. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal, all contributing to better performance and durability. You'll also find an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure. The fully machined crown is another detail that shows these are built for serious work.

This set includes eight pistons, each with a 4.075-inch bore, a 1.299-inch compression height, and a -12.00cc dish volume. They also feature forced pin oiling for better lubrication. Keep in mind these are not CARB approved and cannot be shipped to California.
