Wiseco Pro Tru Street Ford Small Block Windsor 4.040in Bore 1.165in CH -5.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, and their Pro Tru Street series pistons are a prime example of that commitment. If you're rebuilding a Ford Small Block Windsor engine, this set is designed to get you back on the road or down the track with confidence. These pistons are forged from 4032 alloy aluminum right here in the USA, which is a solid material choice for performance street applications.

What sets these pistons apart is the ArmorGlide skirt coating. This isn't just for looks; it's engineered to resist seizures, reduce friction between the piston and cylinder wall, and contribute to quieter operation overall. The dome features are also updated with oil drain-backs, helping to manage oil flow within the combustion chamber. You'll also find that the dome itself is AS-Forged, meaning it's shaped during the forging process for improved strength and precise volume. This set comes complete with chromium alloy steel piston pins, Spirolox clips, and rings, making it an all-inclusive solution for your rebuild budget.

This particular set is for a 4.040-inch bore with a 1.165-inch compression height and a -5.00cc dish volume. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
