Wiseco Pro Tru Street Chevy Big Block 4.310in Bore 1.760in CH 21.00 CC Piston Set

If you're rebuilding the heart of your Chevy Big Block engine, a solid set of pistons is crucial for getting it back on the road or down the track. This Wiseco Pro Tru Street piston set is forged from 4032 alloy aluminum, a well-known material for its strength and ability to handle the demands of a performance street engine. These pistons are made in the USA, at Wiseco's facility in Mentor, Ohio.

What sets these pistons apart is the ArmorGlide skirt coating. This isn't just for looks; it's designed to reduce friction between the piston skirt and cylinder wall, which means less wear over time and a quieter running engine. The AS-Forged dome design includes features for oil drain-back, helping to manage oil flow within the combustion chamber. This set comes complete with chromium alloy steel piston pins, Spirolox retaining clips, and a full set of rings, making it an all-inclusive solution for your engine build.

With a 4.310-inch bore and a 1.760-inch compression height, these pistons are designed for specific Big Block Chevy applications. The 21.00 CC dish volume is a key specification to consider when calculating your final compression ratio. Because these are a performance part, it's important to note they are not CARB approved and cannot be shipped to California.
