Fitting WP9 piston rings without comebacks
Ring sets for WP9 engines are matched to the piston groove and liner finish. The critical checks are end gap in a clean bore, side clearance in the groove, and ring orientation (top ring taper and marking direction). Reusing a worn liner with new rings gives high oil consumption within weeks.
Our WP9 ring sets use chrome-plated top rings and are packed in cylinder sets so you do not mix gaps between bores.
