Wiseco Chevy LT1 4.075in Bore 1.105in CH -15cc Professional Dish Pistons - Set of 8

If you're building a high-performance Chevrolet LT1 engine for serious racing or heavy-duty applications, these Wiseco Professional Series pistons are a solid choice. This set includes eight pistons, each designed with a 4.075-inch bore and a -15cc dish volume, which is crucial for achieving the right compression ratio with your specific cylinder heads and camshaft setup. The 1.105-inch compression height is also a key measurement that ensures proper piston-to-valve clearance and deck height.

Wiseco forges these pistons from 2618 aluminum right here in the USA, giving them improved tensile strength for the demands of racing. They feature precision ring grooves, anti-detonation grooves, and other features designed to enhance ring seal and prevent detonation, which is vital for durability under extreme conditions. The pistons also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their robust design for severe duty performance.

This set is intended for builders who are serious about performance and durability. Remember that these pistons are not CARB approved and cannot be shipped to California. For a successful build, ensure you have the correct supporting components, such as appropriate connecting rods, rings, and bearings, to match the specifications of these high-performance pistons.
