Wiseco Chevy LS 4.145in Bore 1.165in CH 6.00 CC Piston Set

When you're building a serious performance LS engine for racing or heavy-duty use, the pistons are a critical component that needs to handle extreme stress. This set of eight forged pistons from Wiseco is designed specifically for that purpose, featuring a 4.145-inch bore and a 1.165-inch compression height, making them suitable for many popular LS engine configurations.

These aren't your average pistons. They're forged from 2618 aluminum right here in the USA, which gives them improved tensile strength to resist deformation under high cylinder pressures. Wiseco has included precision ring grooves, anti-detonation grooves, and other features to ensure a better seal between the piston and cylinder wall, which is crucial for power and efficiency. You'll also find an ArmorGlide skirt coating, which helps reduce friction for quieter operation and better seizure resistance. The fully machined crown and forced pin oiling further contribute to their ability to withstand severe duty applications.

This set is intended for builders who are pushing their LS engines to the limit. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a high-performance build where durability and power under extreme conditions are paramount, this Wiseco piston set is a solid choice.
