Wiseco Chevy LT1 4.125in Bore 1.105in CH -15.00 CC Piston Set

What you get in this Wiseco K0452X6 kit is a set of eight Professional Series forged pistons, ready to go into your Chevrolet LT1 engine. These aren't your average pistons; they're built from 2618 aluminum, forged and machined right here in the USA, giving them improved tensile strength for serious performance. The 4.125-inch bore size is specific for certain LT1 builds, and the 1.105-inch compression height is a key measurement for setting up your valve-to-piston clearance.

Wiseco has packed these pistons with features for durability and performance under heavy loads. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is critical for power and engine longevity. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, making the engine run a bit smoother and quieter, while also resisting seizure if things get hot. The fully machined crown ensures a clean combustion chamber shape, and forced pin oiling helps keep the wrist pins lubricated, even in demanding race conditions.

These pistons are designed and built to handle heavy to severe duty race applications, so if you're building a serious performance engine, these are a solid option. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct supporting components like rings, pins, and connecting rods, as these are typically sold separately.
