Wiseco Pro Tru Street Chevy Big Block 4.250in Bore 1.270in CH -3.00 CC Piston Set

If you're rebuilding the engine in your Chevy Big Block, a solid set of pistons is crucial for getting the power and reliability you need. This Pro Tru Street piston set from Wiseco is built for that purpose, designed to handle the demands of street driving and occasional track use. They're forged from 4032 alloy aluminum, a material known for its strength and durability, especially when dealing with the heat and pressure inside a performance engine.

Wiseco includes their ArmorGlide skirt coating on these pistons. This isn't just for looks; it helps reduce friction between the piston and cylinder wall, which means less wear over time and a quieter engine operation. The pistons also feature an AS-Forged dome with specific crown features and oil drain-backs, which helps manage combustion and keep oil where it needs to be. You'll also find that this set comes complete with chromium alloy steel piston pins and Spirolox clips, making it a comprehensive package for your rebuild.

This set is specifically for a 4.250 inch bore and has a 1.270 inch compression height. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Everything you need to get started on your engine build is included in this set.
