Wiseco Pro Tru Street Chevy Big Block 4.135in Bore 1.760in CH 21.00 CC Piston Set

If you're rebuilding a Chevy Big Block engine, this Wiseco Pro Tru Street piston set is a solid option. These pistons are built for a 4.135 inch bore and feature a 1.760 inch compression height. They're made from 4032 alloy aluminum, which is a strong choice for street performance builds where you want good durability and thermal expansion characteristics. Wiseco forges these pistons in Mentor, Ohio, ensuring they're well-made right here in the USA.

What sets these apart is the ArmorGlide skirt coating. This isn't just for looks; it helps reduce friction, which can lead to slightly improved efficiency and a quieter running engine. The dome design includes features for oil drain-back, and the pistons come with a chromium alloy steel piston pin and Spirolox clips. This set is designed to be a complete package for your rebuild, including the pistons, rings, pins, and clips, so you have most of what you need to get your engine back together.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For any build budget, Wiseco offers pistons to get you on the road or down the track.
