The RL-300 trailer suspension systems are designed for the most severe duty applications. Our suspensions are built to minimize axle stress and frame fatigue while providing superior tracking and axle alignment.

Extreme Duty Top Mount Fixed Frame Air-Ride
CAPACITY: 30,000 lb. (13,608 kg)
APPLICATIONS: platform, tanker, logger, dump and specialty trailer
ON/OFF-HIGHWAY USE
Standard Ride Heights: 12", 14", 15", 16" and 17"

RIGID TRAILING ARM 

More durable than leaf springs that can break and cause unexpected road problems. Rigid design extends brake and tire life, through better load equalization.

HEAVY DUTY SHOCK ABSORBERS

Rugged, heavy duty shock is engineered specifically for the RL-300. For applications requiring clearance between frame rails, a model is available with shock absorbers mounted below frame rails.

HEAVY DUTY AIR SPRINGS

30K capacity at 88 P.S.I. design increases operating efficiencies. Peripheral mounted air spring is superior to center attachments

FULLY SUPPORTED AIR SPRING MOUNTING PLATE

Protects air spring piston and reduces air spring stresses.

AXLE ADAPTERS

Controls axle movement and reduces axle stress.
