Factors that Affect Air Spring Life

Driving conditions
1. Rough roads, potholes, and off-road driving accelerate wear.
2. Frequent exposure to road salt, wet conditions, or extreme temperatures can cause rubber to deteriorate.

Loading and usage
1. Continuous heavy loads (towing, hauling) can deform air springs.
2. Vehicles equipped with self-leveling suspensions (such as some SUVs and luxury sedans) cycle more frequently, causing faster wear.

Maintenance and care
1. Leaks (due to cracks or punctures) are a common failure point.
2. Damaged air pipes or compressors can cause overwork and premature failure.
3. Regular inspections (every 30,000 to 50,000 miles) can help detect problems early.

Signs of air spring failure
1. Suspension droop (uneven ride height).
2. Frequent compressor operation (indicating a leak).
3. A bumpy or stiff ride (loss of air cushion).
4. Visible cracks or leaks in the rubber bellows.

How to extend their lifespan
Avoid overloading the vehicle. Park the vehicle in a garage (to reduce UV/weather damage).
Replace in pairs (if one fails, the other will most likely follow).
