Description
Piston rings are fundamental to engine efficiency—they maintain compression, control oil consumption, and regulate heat transfer between the piston and cylinder wall. This 4.170″ bore set delivers reliable sealing and durability for high-revving engines, with plasma moly coating to handle sustained performance demands. File fit rings give you the precision needed for a proper installation and consistent ring gap closure.
