Wiseco Pro Tru Street Chevy Small Block 4.030in Bore 1.260in CH -5.00 CC Piston Set

If you're rebuilding the engine in your classic Chevy small block, a solid set of pistons is crucial for getting it back on the road or down the track. This Pro Tru Street piston set from Wiseco is built for that purpose, offering a well-built option forged from 4032 alloy aluminum right here in the USA. They're designed with a -5.00cc dish to work with various compression ratios, and the 4.030-inch bore size is common for many small block Chevy builds.

What sets these pistons apart is the ArmorGlide skirt coating. This isn't just for looks; it's applied to reduce friction between the piston skirt and the cylinder wall, which means less wear over time and a quieter running engine. The pistons also feature an AS-Forged dome with oil drain backs, helping to manage heat and oil flow. You'll also find a chromium alloy steel piston pin and Spirolox clips included, making this a complete package for your rebuild. The 4032 forged aluminum construction means these pistons are strong and ready for street use.

This set includes eight pistons, along with the necessary pins and clips to get them installed. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
