Wiseco Pro Tru Street Oldsmobile 455 4.155in Bore 1.750in CH -15.00 CC Piston Set

This is a set of eight Wiseco Pro Tru Street pistons designed for Oldsmobile 455 engines with a 4.155-inch bore. These pistons are built to get your classic Oldsmobile back on the road or ready for the track, offering a solid foundation for your engine rebuild.

Forged from 4032 alloy aluminum right here in the USA, these pistons are well-built for durability. They feature an AS-Forged dome design with oil drain-backs for better oil control and an ArmorGlide skirt coating. This coating is notable for reducing friction, which can lead to quieter operation and improved resistance to seizure, especially during the critical break-in period and under demanding use. The set includes chromium alloy steel piston pins and Spirolox clips, making it a complete package for your rebuild.

This piston set is designed as a direct fit for Oldsmobile 455 engines with the specified bore size. It comes with everything you need to get started: the eight pistons, pins, and clips. Please note that this part is not CARB approved and cannot be shipped to California.
