Description

The Sealed Power E-288K 30 is a premium piston ring set designed for V8 engines with a 3.800-inch bore. This set features top rings made of moly steel with plasma-moly facings to decrease friction and resist scuffing, while the second rings are constructed from ductile iron. The set includes ring groove widths of 5/64-inch, 5/64-inch, and 3/16-inch.

These piston rings meet or exceed OEM specifications and are manufactured with exacting tolerances. This set of 8 is engineered for precise fitment in applications requiring a +.030 inch overbore.
