The AL-KO tandem Rocker Roller axle system is a load sharing suspension system designed to ensure a smooth transfer of weight from front to rear axle and thus reduce any shock load or vibration on your trailer or caravan. This unique system greatly reduces axle steer and improves stability over rough terrain. Driver fatigue is minimised due to smoother handling and safer towing and less wearing parts ensures lower maintenance costs, over a longer period of time. The AL-KO Rocker Roller is available for 14-inch, 15-inch and 16-inch wheel spacings and suits a Gross Trailer Mass (GTM) of 1900 kg to 4000 kg.

• The correct dimensional set-up is important to ensure all the spring hangers are aligned with each other. This prevents excessive strain on shackle pins.
• Make sure all fittings are tightened securely with nyloc nuts.
• Appropriate shackle pins that are greaseable should be greased.
• The pin through the roller should be greased on assembly.
• The roller and loop eye should only be lightly greased.
