Wiseco Chevy LT1 4.065in Bore 1.299in CH -12.00 CC Piston Set

Starting with a 2618 aluminum forging, these Wiseco pistons are machined in the USA to handle the demands of serious racing builds. The 4.065 inch bore size is specific for certain Chevrolet LT1 applications, and the -12.00cc dish volume is designed to achieve a specific compression ratio when paired with the right cylinder heads and crankshaft. This set includes eight pistons, each featuring precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal and overall performance under heavy load.

Wiseco's Professional Series pistons come with an ArmorGlide skirt coating. This isn't just for looks; it helps reduce friction between the piston skirt and cylinder wall, which can lead to quieter operation and less wear over time, especially in high-stress environments. The fully machined crown and forced pin oiling are further details that speak to their design for severe duty use. These are well-built components intended for builders who are serious about extracting maximum performance and durability from their LT1 engine.

When rebuilding or modifying your LT1 for heavy-duty racing, consider the specific requirements of your build. This piston set is designed to be a strong foundation, but remember to consult your engine builder or a trusted resource for recommended pairings with crankshafts, connecting rods, and cylinder heads to achieve your desired compression ratio and performance goals. Please note that these pistons are not CARB approved and cannot be shipped to California.
