Haigh levelling ramps are designed to take both single and tandem axle vans. They can cater for off-road vans and cater for vans upto 5 Tonne and tyre widths of 250mm.
The levellers are lightweight and only weigh 1.8kg each. They can be spilt into two pieces to allow different options of use, by separating into 4 sections.
Can raise the wheel of your van upto 10mm, without using a jack.
Great to solve that uneven ground issue.

There is also an option of individual red chocks, that can be purchased and used with these ramps. Not essential.
