Proper maintenance extends shock life by 50%—here’s your HPR checklist:
Post-Trail Check (Every Use): Wipe debris from the shaft, inspect for dents or leaks, and lubricate mounting bushings with silicone spray (avoid petroleum-based oils, which degrade NOK seals).
Monthly Tune-Up: Check nitrogen pressure with a digital gauge (target: 0.7-0.8MPa). Low pressure? Recharge at an HPR service center—never overinflate, as this causes seal wear.
Seasonal Service (Every 6 Months): For harsh environments (salt, mud), disassemble and clean the reservoir, replacing the foam filter if clogged. Grease the adjuster knob to prevent sticking.
Annual Inspection: Have a professional dyno-test damping force—HPR shocks should lose <5% efficiency annually if maintained.
Neglect leads to costly failures: a seized piston rod can damage control arms, while worn seals let dirt into the oil, causing abrasive wear. Our shock maintenance video walks you through each step, including tools needed. For Mitsubishi Pajero owners, don’t forget to inspect the anti-corrosion coating on our heavy-duty shocks—applied in a 3-stage process for coastal or winter use.
