Cylinder Seal Kits

Hydraulic cylinder seal kits—also known as repacking kits—for Cottrell and Boydstun car hauler trailers. These kits stop leaks and restore proper lift and slide function on deck and post cylinders by replacing worn seals, wipers, and O-rings. Match kits by rod and bore size to ensure correct fit and reliable performance. Repacking a leaking cylinder extends service life and reduces the cost and downtime associated with full cylinder replacement.
