Wiseco Chevy LS 4.130in Bore 1.165in CH -12.00 CC Piston Set

If you're building a high-performance Chevrolet LS engine for serious racing or severe duty applications, this Wiseco forged piston set is a solid choice. These pistons are designed to handle extreme conditions, offering improved tensile strength and durability thanks to their construction from 2618 aluminum, forged and machined right here in the USA. The 4.130-inch bore size and -12.00cc dish volume are specific to certain LS engine builds, and the 1.165-inch compression height is crucial for achieving the correct deck height and compression ratio in your engine.

Wiseco has packed these pistons with features aimed at maximizing performance and longevity. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is critical for maintaining compression and preventing blow-by under high stress. The pistons also come with forced pin oiling to ensure the wrist pin stays well-lubricated, and they feature a fully machined crown for accuracy. Additionally, the ArmorGlide skirt coating helps reduce friction and resist seizure, while also contributing to quieter operation.

This set includes eight pistons, ready for your next engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a successful installation, always refer to the manufacturer's detailed specifications and recommended assembly procedures.
