Wiseco Pro Tru Street Chevy Big Block 4.280in Bore 1.270in CH -3.00 CC Piston Set

If you're rebuilding the heart of your Chevy Big Block engine, a solid set of pistons is crucial for getting your ride back on the road or down the track. This Wiseco Pro Tru Street piston set is forged from 4032 alloy aluminum, a strong material chosen for its balance of durability and weight. These pistons are made right here in the USA, in Mentor, Ohio.

What sets these pistons apart is the ArmorGlide skirt coating. This isn't just for looks; it's designed to resist seizing, reduce friction, and help keep your engine running quieter. The pistons also feature an AS-Forged dome with specific crown features and oil drain backs, which are important for proper combustion and oil management. You'll also find that this set comes complete with chromium alloy steel piston pins and Spirolox clips, meaning you get everything you need for an all-inclusive rebuild in one box.

This set is specifically designed for a 4.280-inch bore and has a 1.270-inch compression height. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
