The Tough Touring Air Bag kit Replaces the coil springs on your UEV 440 or 490. 
 
In Conqunction with Boss Air Suspension and All Terrain 4x4 - we have developed a 'Bolt in' Air bag kit which replaces the present coil springs. Travel retaining straps are changed, and brackets attached to the boss air bags have been manufactured to allow them to bolt into position where the factory springs usually seat. The Kits have been tested in the field and the results have been very positive with enhanced manners on and off-road. Some reduction in roll is achieved on top of the obvious benefits for levelling up and lowering for garaging... Total vehicle height at full lowered position is approximatly 2150mm - ...  The kit includes all parts required including retaining straps, upper and lower brackets, air bags, air lines, schroder valves for left and right side. You will need an Air compressor for re-inflation, and we'd reccommend also looking at shorter stroke shock absorbers for even lower drop figures.
