BOS 400mm Stabiliser Legs, 2 Legs per box
Heavy-duty 400mm stabiliser legs — lift-rated and drill-friendly
Why this product?
Standard square caravan legs flex, sink into soft ground, and are slow to operate. BOS 440-041 replaces them with a high-torque gearbox system rated to 1800kg per leg — strong enough to lift the van for a tyre change.
- 1800kg per leg — lift-rated to change a tyre
- Direct bolt-in replacement for standard legs
- Patented PUSH/PULL Handle for easy release
- 30° or 90° positions for uneven terrain
- Hand or cordless drill operation
- 5 Year Warranty

Tip: Measure your existing legs before ordering — ensure caravan is level when measuring. You may need different heights at front and rear.
Why this beats the alternatives
Australian made, 1800kg rated per leg, and designed with the patented PUSH/PULL Handle for one-handed repositioning. Weight transfers to the base — not the pivot bolt — so the van genuinely doesn't move once they're down.
Who it's for
Caravan owners upgrading from factory stabiliser legs who want a system that actually stabilises the van and can handle a tyre change.
