- Internal seal damage - the most frequent failure cause
- External air line and fitting wear leading to pressure leaks
- Normal component wear over time - expected lifespan of 75,000+ miles
- Inability to maintain proper air pressure
- Bouncy suspension due to insufficient damping
- Clunking or unusual noises during compression and rebound
- Unstable and unsafe ride quality for passengers
- Potential damage to hauled property due to excessive bouncing
Air shocks operate similarly to conventional shock absorbers, managing compression and damping forces during suspension movement. When encountering road irregularities, the suspension compresses and rebounds, with damping controlling these forces. For heavy load applications, air shocks provide enhanced support when combined with heavier springs, ensuring safe transportation of substantial cargo. The system includes metal fittings, plastic air hoses, and Schrader valves for inflation using standard air pumps, with regular moisture purging required for optimal maintenance.
