The axles of ITS boast a simple, integrated design featuring a torsion suspension system. Within the axle housing, there are four rubberized cords responsible for managing both suspension travel and shock absorption. Furthermore, this setup enhances trailer stability, as the axle is securely bolted to the trailer frame. BENEFITS: The main advantages of a torsion bar suspension are soft ride due to elasticity of the bar, durability, and small profile along the width of the vehicle. ADVANTAGES: Smother ride & lower more ground clearance: Self-damping action and independent suspension, ITS delivers a smooth, quiet ride like no other – adding up to an improved towing experience. Also, by bolting the axle up close to the chassis this give more ground clearance than traditional spring & axle setup. Lower Maintenance: Except for periodic inspection of the fasteners used to attach the ITS axle to the Trailer frame, no other suspension maintenance is required on ITS axles. They are, of course, subject to normal maintenance and inspection procedures regarding brakes, hubs, bearings, seals, wheels and tyres.
