How do Air Springs Benefit Trailers
- Eliminate squat and sag: Air springs help lift the rear end of the vehicle when carrying a heavy load, preventing it from sitting low. This is especially beneficial while towing, as the air springs can be adjusted to accept the tongue weight of the trailer .
- Improved braking and steering: Air springs ensure that weight is properly distributed to all four tires, improving braking and steering performance. This is particularly important when towing, as front tires account for the majority of braking and steering .
- Proper headlight aiming: Air springs help maintain a level and stable vehicle, ensuring that headlights are properly aimed at the road. This is critical for safe night driving .
- Reduced trailer sway: Air springs help reduce trailer sway caused by strong bursts of wind or other external factors. This improves stability and control while towing .
- Enhanced ride quality: Air springs provide a smoother and more comfortable ride compared to traditional leaf spring suspensions. They absorb shocks and vibrations from the road, resulting in reduced driver fatigue and increased comfort for passengers or cargo .
- Load equalization: Air springs enable near-perfect load equalization between axles, ensuring that the cargo stays in place and out of harm's way. This helps maintain stability and safety during transportation .
- Durability and reduced maintenance: Air springs are designed to withstand heavy loads and provide durability. They have fewer components to check and maintain compared to other types of suspensions, reducing downtime and equipment failures .
