This was another new job for me – never had or seen an air suspension kit before! The reason for having it is to give a better less clashy ride and allow us to have a level van with no tail sag.
Air assistance kits come with various features at various price points, so determining the functionality you want is important. With 1700+ nights camping with no air suspension I cannot see us adjusting it daily when parking. I see us installing it and forgetting it. Thus, I do not want a dedicated compressor, nor do I need cab-controls to adjust it. Also I do not wish to modify the cab. I will have a portable compressor anyway and will have +12v next to the dials.
Some kits don’t come with pressure gauges, or have a single connector. I want pressure gauges to help with adjusting and knowing if there is a leak, and I want independent OS/NS settings to balance the van if needed.
An ebay kit from seller ( HERE ) was £249 so amongst the cheapest, but the customer service, pre-sales was brilliant, and they sold me a second gauge as requested.
The bags are branded Rubena, rated for 4T, and the brackets the seller provides are brilliant. Fit perfectly, very cleverly designed, and simply screw up into the bump-stop threaded hole, and the bottom clamps around existing bracket. You do NOT need to remove any existing suspension bolts at all – so easily reversable
On a new van, the bump stops came out easily 🙂
- Do this job early with little weight in, then the bump stop unscrews easily. (On older vans, the bump stop thread may be rusted… Good luck!)
- A long hacksaw blade is easy to cut the ABS sensor cable bracket. Any power tools here are high risk of damaging something important!
- Use conduit where the airline needs securing or goes into chassis to prevent rubbing, and leave enough slack for extreme suspension movements.
- Do not connect the airline to the bellows until bellows in situ as you need to squeeze the air out.
Overall, nice and easy job!
(Note: Other kits are very similar, but some require you to remove the rear spring U bolts. Some require 12v for the compressor. And where you route the gauges and filler will be personal choice and pose it own issues. Mounting in the garage and using the same route as towbar electrics was simple)
If you want to adjust suspension each time you move a can of beans around, you need a different kit with compressor and dash controls.
