Wiseco Pro Tru Street Chevy Big Block 4.280in Bore 1.760in CH 21.00 CC Piston Set

Forged from 4032 alloy aluminum right here in Mentor, Ohio, these Wiseco Pro Tru Street pistons are built for your Chevy Big Block. They're designed for a 4.280-inch bore and feature a 1.760-inch compression height, making them a solid choice for rebuilding your engine. The ArmorGlide skirt coating is a notable feature that helps reduce friction, leading to quieter operation and better resistance to seizing, which is always a good thing when you're pushing your engine hard.

Wiseco includes everything you need for a complete rebuild in this set: the pistons themselves, chromium alloy steel piston pins, Spirolox retaining clips, and a full set of rings. The AS-Forged dome design also incorporates features for oil drain-back, helping to keep things lubricated and running smoothly. This is a well-built set intended to get your street machine or track car back on the road or down the strip reliably.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For most other applications, this set offers a comprehensive solution for your Big Block Chevy engine build.
