Wiseco Pro Tru Street Chevy Big Block 4.255in Bore 1.350in CH -2.00 CC Piston Set

Forged from 4032 alloy aluminum right here in Mentor, Ohio, these Wiseco Pro Tru Street pistons are built for serious Chevy Big Block builds. They're designed for a 4.255-inch bore and feature a 1.350-inch compression height, with a -2.00cc dish volume in the dome. This specific dish volume is important for achieving your target compression ratio, especially when paired with specific cylinder heads and head gasket thickness.

Wiseco's ArmorGlide skirt coating is a notable feature here. It's applied to reduce friction, which helps with quieter operation and resists seizing, especially during the critical break-in period and under demanding use. The AS-forged dome design includes features for oil drain-back, helping to manage oil flow within the combustion chamber. You'll also find the pistons come with chromium alloy steel piston pins and Spirolox retaining clips, making this a truly all-inclusive set ready for your engine rebuild.

This set includes eight pistons, along with the necessary rings, pins, and clips, so you have everything you need to get your engine back together. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
