Pro Tru Street Series Dome Piston Set

The Wiseco Pro Tru Street Series Dome Piston Set offers high-performance capability for street machines. Forged from 4032 aluminum, these pistons are built for durability and performance, complete with chromium alloy steel piston pins and Spirolox. Engineered for budget-conscious builds, these pistons are designed to work with factory connecting rods and feature a small .090” dome to slightly increase compression. The .280” top land and 4035 alloy construction are suitable for nitrous use. Key features include oversized, symmetrical, and radiused valve pockets that accommodate LS1, LS2, LS3, LS6, and cathedral port aftermarket cylinder heads, allowing for maximum flow around valves during overlap. The ArmorGlide® skirt coating enhances piston life, increases horsepower, reduces noise, and provides tighter dimensional tolerances than conventional coatings. Specifications include a 4.000" bore size, 3.622" stroke, 1.335" compression height, and a .945" wrist pin.
