Our load-sharing Simplicity Axles™
are the best caravan and trailer axles you can buy.

 

Whether you want to cruise the highways or explore the outback four-wheel-driving, 

our load-sharing Simplicity Axles™ are the best caravan and trailer axles you can buy. 


If you need to fit a work trailer, horse float, or agricultural implement for years of reliable service, we can tailor a system to meet your needs – with up to 4.4 tonne capacity.

 

Our systems can be made in a range of configurations, depending on your load-bearing and travel requirements. Our legendary leaf spring design and patented Smart Coil spring are both available in tandem and single axle systems. We also offer a tandem airbag system and an agricultural tandem system designed for heavy-duty off-road work.

Simplicity Smart Coil

The Simplicity Smart Coil is available in both single axle configuration from 1400 kg and tandem axles from 2500 kg. 

Airbag tandem systems

With a load capacity up to 4200 kg, our tandem airbag systems are a popular option for touring vans travelling mostly on sealed roads, with some off-road travel.

Tandem axle systems
(on & off-road)

Leaf spring: 2250 kg to 4400 kg

Coil spring: 2500 kg to 4400 kg (Available in twin trailing arm or single beam leading arm/trailing arm configuration.)

 

Achieves full wheel articulation in an
unladen state.

Airbag tandem systems

Up to 4200 kg

Load-sharing Coil (LSC)

Our patented LSC design applies the Smart Coil to a tandem system for heavier caravan and trailer loads from 2500 kg to 4400 kg. 

Leaf spring axle systems

Our leaf spring systems also feature our load-sharing design and full wheel articulation, without requiring shock absorbers. Available in single and tandem systems.

Single axle systems
(on & off-road)

Rubber spring: up to 750 kg

Leaf spring: 1500 kg to 2500 kg

Coil spring: 1400 kg to 2600 kg

For lighter loads, our convoluted rubber spring systems with trailing arm offer a very light cushioned ride. Leaf springs or coil springs are used on our 1400 kg and
heavier units. 

Note: It is essential that the appropriate wheels

and tyres be fitted, suited to each configuration.

Agricultural Tandem
(off-road only)

Up to 4400 kg 

We believe Tandem Simplicity Axles™ Systems are the only proven long-term Independent Load-Sharing units available in the light trailable vehicle market.
