Description

The Total Seal ML3690-30 is a set of high-performance piston rings, likely from their Gapless or Max Seal series. These rings are designed to improve engine performance by providing a superior seal in the combustion chamber, which helps reduce blow-by, improve horsepower and torque, and optimize oil control. Piston rings are critical components that transfer heat from the piston to the cylinder wall and prevent combustion gases from escaping past the piston. Inferred specifications: Bore Diameter: 4.000 inches, Ring Thicknesses: 1/16" (top ring), 1/16" (second ring), 3/16" (oil ring).
