Wiseco Pro Tru Street Chevy Small Block 4.040in Bore 1.425in CH -5.00 CC Piston Set

Forged from 4032 alloy aluminum in Mentor, Ohio, these Wiseco Pro Tru Street pistons are built for your Chevy small block engine. The 4.040-inch bore size is a common starting point for many rebuilds, and the -5.00cc dish in the dome helps achieve a desired compression ratio, especially when paired with specific cylinder heads. This set is designed to get your vehicle back on the road or ready for the track.

Wiseco includes an ArmorGlide skirt coating, which helps reduce friction for quieter operation and offers resistance to seizing. The pistons also feature an AS-Forged dome with specific crown features and oil drain-backs, contributing to better performance and longevity. You'll also find a chromium alloy steel piston pin and Spirolox clips included, making this a comprehensive package for your engine build.

This piston set is intended for a complete engine rebuild. Ensure you consult your engine's service manual or a trusted mechanic for proper installation procedures and to confirm compatibility with your specific cylinder heads and crankshaft.
