Ultimate suggested airbags in my case,
the occasional caravan trip, under loaded but needed some levelling out.
Havn't purchased yet, got some saving/begging to do

I have compared your vehicle details and driving conditions against our database and have put together a suspension set-up to suit your requirements. This suspension upgrade will vastly improve the comfort, handling and load carrying ability of the vehicle, both empty and when towing.
On the front, I recommend our Raised Heavy Duty coils. These coils will work perfectly with the bull-bar and up-coming winch, supporting these accessories at approximately 40mm over standard height without sacrificing comfort. In the rear, I would run with a modified Comfort leaf spring and Firestone Ride-Rite Airbags. This set-up will provide the best of both worlds; Great comfort when the vehicle is empty without compromising the load-carrying requirements for when towing. This will not increase the actual mass able to be towed, but will allow the vehicle to handle these weights much more efficiently.
I then recommend we match these springs with our Aussie Ryder Twin Tube Gas shock absorbers. The Twin-Tube design is reliable and robust, having proven itself across some of the harshest tracks in the Australian Outback. These shocks are completely re-buildable and, as such, we are able to customise the valving to suit the spring rates used on your vehicle. These shocks also come with a 2yr/80,000km warranty (whichever comes last).
