Service seal kit for a lift cylinder rebuild, covering rod seals, wipers, and o-rings to stop hydraulic weep and restore lift speed. Mast cylinder reseals are a routine job once a truck starts dropping load or showing oil streaks down the rod. Hydraulic shops and PM teams resealing cylinders, axles, and gearboxes during routine overhauls use seals like this on most jobs. A weeping seal slowly drops fluid level and lets contamination into the system, so timely replacement keeps pressure and lubrication where they belong.Aftermarket replacement part, cross-references original part number AC-4908917.Need help confirming fit?
