Upgrade your Small Block Ford engine with the Wiseco-Pro Tru PTS501A3 piston and ring set, engineered for dependable performance in demanding street and competition applications. This kit includes forged flat-top pistons designed for a 4.030-inch bore and a 1.769-inch compression height, providing a practical foundation for performance-focused engine builds. The flat-top design supports consistent combustion characteristics while the minus 7.00 cc volume helps builders fine-tune compression based on the selected cylinder head, gasket, and deck configuration.
The Wiseco-Pro Tru PTS501A3 set uses 1/16-inch, 1/16-inch, and 3/16-inch ring grooves to accommodate compatible piston rings and promote effective oil control. Forged construction offers strength and durability under increased cylinder pressure, making this piston set well suited for Small Block Ford applications where reliable performance and precise fitment are essential. Verify bore size, compression height, piston-to-valve clearance, ring selection, and final compression ratio before installation.
Designed as a matched piston and ring kit, the PTS501A3 helps simplify component selection for a complete engine build. Its application-specific configuration is intended for Windsor-style Small Block Ford engines, giving engine builders a dependable replacement or performance upgrade option.
