5. 🔧 Eliminates Common Spring Suspension Issues
   ITS suspension removes the need for outdated spring-and-axle setups, which often suffer from:
   – Spring bolts wearing out
   – Snapping springs or shackles
   – U-bolts loosening or breaking, leading to wheel and mudguard damage

   ITS includes a built-in guide wheel mechanism that ensures both left and right brake callipers are pulled evenly for safer, more reliable braking.

7. ⚙️ Self-Adjusting Brake Cables
   Unlike spring setups, the ITS cable system doesn’t require constant adjustment when loads change — making it easier to maintain.

8. 🔩 Reinforced Cage Mounting
   50x50mm tube inserts are used to securely mount the cage, offering superior strength compared to bolt-on cage systems.

9. 🧱 Heavy-Duty Cage Frame
   Built from robust 40x40mm steel with functional front and rear access doors.

WHAT IS ITS SUSPENSION: INDEPENDENT TORSION SUSPENSION 

ITS axles have a straightforward, attached construction with a torsion suspension system. Four rubberized cords are inside the axle housing which handle suspension travel and shock absorption. In addition, this system offers trailer rigidity as the axle is 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.

Traditional leaf springs, axles and all the componentry may fatigue over time and break whereas the ITS suspension has less componentry eliminating this issue.
