You’ve invested in HPR CDC Nitrogen shocks for your GWM TANK 300—now, how do you keep them performing at their best for years to come? Proper maintenance is key, and luckily, these shocks are designed to be low-maintenance. Here are our top tips for keeping your CDC shocks in top shape.
1. Regular Cleaning
Off-roading means mud, dust, and debris—and that can build up on your shocks. After every trail run, rinse the shocks with clean water (avoid high-pressure washers directly on the seals) to remove dirt and grime. This prevents debris from scratching the shock body or seeping into the seals, which can cause leaks over time.
2. Inspect Seals & Hoses
Every 3-6 months (or after intense off-roading), check the shock seals and hoses for signs of damage. Look for oil leaks (a wet, greasy film on the shock body) or cracks in the hoses. HPR uses high-quality Japan NOK seals (same as KYB OEM shocks) and durable hoses, but regular inspections catch small issues before they become big problems.
3. Check Nitrogen Pressure
While HPR CDC shocks are pre-charged with nitrogen and sealed for life, extreme conditions (like repeated bottoming out or extreme temperatures) can occasionally cause pressure loss. If you notice a sudden change in ride quality (softer than usual or more bouncing), have a professional check the nitrogen pressure. Most off-road shops can do this quickly.
4. Avoid Overloading Your Vehicle
CDC Nitrogen shocks are designed to handle the GWM TANK 300 weight and typical off-road loads, but overloading (hauling too much gear or towing beyond capacity) puts extra stress on the shocks. This can lead to premature wear or reduced performance. Stick to your vehicle weight limits for the best results.
5. Calibrate After Suspension Modifications
If you add other suspension upgrades (like lift kits or new control arms), have your CDC shocks calibrated by a professional. This ensures the sensors and damping adjustments work with your modified suspension, maintaining optimal performance.
Follow these tips, and your HPR CDC Nitrogen shocks will keep delivering smooth, controlled rides—trail after trail, year after year.
