Piper Seat Adjustment Spring

The Piper seat adjustment spring is a direct replacement. One spring is required per bucket seat. Some Piper parts catalogs do not list PN 587-404 separately, but list an assembly PN 89178-010 instead. PN MC587-404 replaces the spring component of this assembly. This part replaces Stabilus Bloc-O-Lift or Gas Spring Corp. Easy lift-style springs. Does not replace Piper PN 76445-000 (P.L. Porter HydroLock style spring).
