The Flexiride rubber torsion axle consist of three primary components: a rubber cartridge, support bushing and spindle arm. The cartridge is comprised of strong proprietary formula rubber bonded to a steel shaft. The bonding process used results in a bond strength exceeding the strength capabilities of the associated steel parts.

Unlike the solutions used by competition, the system operates in shear rather than compression providing more angular compliance, a better damping effect and a smoother ride. The nylon support bushing maintains camber and contributes additional damping control.

The spindle arm is a one piece forging with a splined joint connecting it to the cartridge. The splines, at six degree intervals, make an exceptionally strong connection while providing a range of starting angles.

Components are available in four sizes: 2000, 3500, 5200, and 7000 lbs axle capacities.

Flexiride® Advantages versus Leaf Spring Axles:

Durability: The cartridge construction offers superior resistance to abrasive road elements, increasing the life and durability of the axle. Because the cartridge is press fit inside the axle tube, it forms a water ltight seal, thus allowing the axle immersion without having the tube inside exposed to corrosion.

Smoother ride and longer life:  The high quality proprietary formula rubber guarantees a smoother ride and longer life. The independent suspension allows each wheel to travel totally independent from the others. A smoother ride, less sway and reduced noise is achieved with the rubber suspension.

Progressive Torque: It increases carrying capacity as the lad is applied, allowing smooth ride even with an unloaded trailer.

Safer and stronger:  The specially engineered one piece forged spindle arm creates a system which is safer and stronger than any welded unit. The axle tube acts like an extra cross memeber, adding strength and preventing frame twisting. The rubber cartridge is completely encapsulated inside the axle tube, so there are no pinch points.

Adjustable:  The splined arm is adjustable for a range of starting angles to suit special applications. The axle can be built with various start angels to achieve desired trailer height.

Damping Control: Because of the rubber natural vibrations absorbing capabilities, no shock absorbers are required.

Easy replacement:  Unlike welded systems the Flexiride® spindle arm can be removed easily for repair or replacement.

Quick installation:  The axle assembly requires only four bolts to mount reducing installation time.

Maintenance Free: Because there is no metal-to-metal contact, there it eliminates the need for lubrication of the components. There are no suspension parts to wear out. (spring shackles, hangers, etc.)

Delivery:  Built-to-suit axle system reduces lead times and inventory.

Warranty: UCF offers a five year warranty on components, that demonsttrates how confident they are with the Flexiride suspension.
