Wiseco Pro Tru Street Chevy Small Block 4.060in Bore 1.260in CH -5.00 CC Piston Set

If you're rebuilding a Chevrolet small block engine, this Wiseco Pro Tru Street piston set is a solid option for getting your build back on the road or track. These pistons are designed for a 4.060-inch bore and feature a 1.260-inch compression height, with a dish volume of -5.00cc. They are manufactured in Mentor, Ohio, from 4032 alloy aluminum, a material chosen for its good balance of strength and thermal expansion properties, which helps reduce piston slap and noise.

Wiseco includes an ArmorGlide skirt coating on these pistons. This coating helps reduce friction between the piston and cylinder wall, leading to quieter operation and improved resistance to seizure. The pistons also feature an AS-Forged dome with specific crown features and oil drain-back designs to help manage combustion and lubrication. For durability, each set comes complete with chromium alloy steel piston pins and Spirolox retaining clips, making it a comprehensive package for your engine rebuild.

This set includes everything you need to get started on your engine build: eight pistons, eight pins, eight sets of clips, and a full set of piston rings. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper assembly and break-in procedures.
