Wiseco Pro Tru Street Chevy Small Block 4.060in Bore 1.125in 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 choice for getting your build back on the road or down the track. These pistons are forged from 4032 alloy aluminum right here in the USA, specifically designed for street applications where durability and smooth operation are key. The 4.060-inch bore size is a common starting point for many small block builds, and these are designed to fit that specification.

Wiseco includes everything you need for a complete installation in this set: the pistons themselves, high-quality chromium alloy steel piston pins, Spirolox retaining clips, and a set of rings. A notable feature is the ArmorGlide skirt coating, which helps reduce friction for quieter operation and offers resistance to seizure, a common concern in street engines. The pistons also feature an AS-Forged dome with specific crown features and oil drain-backs, further contributing to their performance and longevity in a street-driven vehicle.

This set is designed for a 1.125-inch compression height and has a -5.00cc valve relief volume, which is important for proper valve-to-piston clearance in your specific cylinder head application. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for precise details on fitting these pistons into your engine block.
