One Piece Spindle Arm

  • Superior one piece forging design is safer and stronger than welded units.
  • Splined spindle arm is adjustable for a range of starting angles to suit special applications.
  • Easily adjust trailer height.
  • Removable for repair or replacement.
  • Integral flange standard on 2,000 and 3,500 lbs axles.

Axle Brackets

  • Quick and easy installation; axle assembly requires only four bolts to mount.

Axle Tubing

  • Acts as extra cross member adding strength and preventing frame twisting.
  • Tubing has built-in camber to compensate for deflection under load.

Unique Rubber Cartridge Design

  • High quality proprietary rubber guarantees smoother and longer life.
  • Strength of rubber to metal bond exceeds strength of associated steel parts.
  • Superior vibration dampening.
  • Progressive torque increases carrying capacity as load is applied for improved ride on unloaded trailers.
  • Solid cartridge design offers superior resistance to abrasive road elements increasing life and durability of axles.
  • Press fitted cartridge reduces water penetration and corrosion exposure; ideal for marine applications.

Nylon Support Bushing

  • Maintains axial position of the cartridge shaft.
  • Contributes additional damping control.

Retainer Plate

  • Allows the support bushing to float freely in the tube to reduce friction.

Lubed Spindle

  • Non – Lubed optional

Rubber torsion axles offer a superior ride compared to leaf spring suspensions especially in unloaded trailers.

Vibration Dampening Technology

Flexiride® axles provide the smoothest ride in the market. The solid rubber cartridge works in shear as opposed to compression providing more angular compliance and superior vibration dampening compared to cord type axle systems. No shock absorbers are required due to rubber’s natural vibration absorbing capabilities.

Adjustable Arm Starting Angles

The splined joint connecting the spindle arm to the cartridge is exceptionally strong. Positioned at 6° increments, the splines provide a range of starting angles to fit a wide variety of applications and allowing trailer height adjustment. Unlike welded units, the Flexiride® spindle is easily replaced by removing the pinch bolt, nut and washer.

FLEXIRIDE® Build-To-Suit Axle System

The Flexiride® rubber torsion system is simple and easy to manufacture. Four basic components are at the core of this axle system: the rubber cartridge, spindle arm, bushing and retainer plate. Available in four sizes, these components cover capacities ranging from 1,400 lbs to 7,000 lbs. The axles are manufactured by licensed manufacturers throughout the United States and Canada.

The Flexiride® Licensee program is ideal for trailer and smaller axle manufacturers wishing to build torsion axles in-house and for manufacturers of specialty trailers requiring the durability and versatility of the cartridge system.

Maximum Versatility

  • Customize your Flexiride® axles by selecting different track width and starting angles.
  • Build full beam axles, v-bend boat trailer axles and half axles using the same basic components.

No Specialized Equipment Needed

  • Unlike rubber cord axle systems, the Flexiride® system does not require freezing the rubber prior to installation.
  • A general hydraulic press is required to press fit the rubber cartridge in the tubing.
  • Basic welding equipment and capabilities are required.

Reduce Inventory and Lead Times

  • Build axles on site to different length to fit any application with minimal lead time.
  • Easily adjust starting angle by positioning the splined spindle arm.
  • Downrate the axle by cutting the cartridge to accomodate a wider range of axle capacities.

Compatibility with industry standard components

  • Flexiride® axles fit industry standard hubs, drums and brakes.
  • Compatible with Kodiak disc brakes.

Five Year Warranty

  • The Universal Group offers a five year warranty on all its components.
