This is a brand new BOSS air bag load assist kit to suit the rear of. Mercedes Sprinter Van and Cab Chassis with 4″ (100mm) Rear Axle tube – not 3″. We have a separate listing (LA85) for the 3 Rear Axle. This kit assists your rear leaf suspension. Rated at 2500 Lb per Bag = 5000 Lb. For environmental reasons we have moved away from the old zinc plate finish to a new high quality black powder coating with anti corrosive preparations. If you carry heavy loads at all you should consider heavier springs of some sort. But the problem with heavier springs is that when you don’t have a load they are rock hard and not only does it feel terrible but the car handles poorly. If your load varies you need soft suspension when you don’t carry a load and heavy suspension when you do have a load. Cant manage that with heavier leaf springs. The only real way to achieve this is with air bags just like those in trucks and buses. 100% Bolt on – so easy to fit. With a BOSS Air Bag Load Assist kit you can run them with zero pressure when you are running light weight without a load. Then just pump them up when you load up. The heavier the load the more air you can apply. These will safely load up. To 150 psi and carry 2500 Lb per bag = 5000 Lb. Typically when loaded you would run at about 40-60psi. Our customers report back with that as being a surprise bonus feature. Each bag has its own air line and valve. By keeping them separate and not allowing air to transfer between bags we eliminate body roll. It is ok to take a leaf or 2 out of their rear leaf pack. This softens up the ride to softer than standard. Then run a few pounds to suit your liking in the bags. Now you are running on air, even without a load. The kit is complete. Brackets top and bottom. Air Bags x 2 (1 for each side). Air Fittings for air lines. Easy to follow instructions with pics. Essentially you can lift the rear of the vehicle with air bags to level when otherwise sagging in the rear. You can avoid your headlights blinding oncoming drivers when your rear end sags. Shocks, tyres and leaf springs will last longer too. The steel brackets are very heavy duty. We can also help with on board air compressor, tank, in cab kit so you can have full control from inside the vehicle. The PX02 In Cab Kit. Or if you want to also run air tools, tire inflation kits and diff locks then you should check out our heavy duty PX07 In Cab Kit which includes our large PX07 compressor and tank and all the parts needed to manage a supply of air and operate your bags. All of our gear is sent anywhere in USA and Canada (or with express options) or Worldwide at affordable rates. Almost every air bag application we do is bolt in. No welding or cutting or drilling. We make that a mandatory requirement when we develop a new kit. Our bags are not permanently attached to the mounting brackets. That means you can replace a bag if you have to without the costly new brackets as well. No need for qualified installers, anyone can fit our gear and its easy. We talk with farmers, trades people travelers and snow birds every day about their load carrying and air system needs and we take pride in making our mark. We have been doing air suspension for over 15 years and have over 20,000 customers out there running BOSS air suspension products. Over the years we make improvements where we can and so by now we have become a market leader recognized for having the best product at the best prices. BOSS also have a development center in Australia looking after our Australian and Asian interests. At BOSS we dont copy others – To begin with we dont trust the others to get it right. But more importantly the others dont have anything to copy. BOSS are the first to get hold of new vehicle models and get kits to market having tried and tested them, fully getting to understand the vehicle and the engineering required. For example BOSS were the first to market with Dodge Promaster, Ram coil assist kits, F150 2015+ and many others. As such BOSS have the widest range of applications for USA and Australian markets. BOSS have the most comprehensively wide range of accessories as well. All of our air compressors can be rebuilt and we stock those parts. We have tanks, pressure switches, water filters, braided lines, digital pressure gauges, everything for in car operation of your bags, the list goes on and on. BOSS air bags are manufactured in our BOSS factory with our own machines to our own exacting standards and specifications. We strongly believe it’s the only way of maintaining strict control over the bags. Here are some interesting facts… It takes over 20 minutes for each bag to go from the raw un-cured blended rubber to a cured air bag. 1 machine can only make 1 bag at a time. Its not just the thickness of the rubber that gives the bag its strength but also the angle of the reinforcing cords and design of the woven beads. The proprietary ballistic material used for the woven reinforcing on the airbag wall, along with the specific spacing and angle of the weave, is what gives our air bag its unique strength. The bead ring ends of the bag are constructed of 4 Hi-tensile cords at each end, ensuring that the top and bottom hold their shape and cant be pulled away from the Aluminium clamping ring. The center of the air bag (the part of the bag with the most stress) is constructed using 9 strands of Hi-Tensile steel to form an indestructible center support. Our competitors’s bags have less than half these strands and so half the strength. The BOSS airbag machines are operated at over 400psi while the curing process is taking place with very high heat. There’s an internal bladder pushing the airbag case into the mould ensuring consistency throughout the airbag wall. Each air bag machine has over 50 tons of clamping pressure on the mold during curing. Effectively these are desperately over engineered as there’s no way you could ever exert over 50t and 400 psi on a bag in your vehicle. The factory tests selected bags to destruction within a controlled chamber to ensure continued bag quality and identify possible ways to constantly improve the design and technique. We have just recently released the exciting new EX-2 Bags. They have a 5 year leak free guarantee. Tooling was modified to provide for a heavier and wider rim width. BEWARE: Some other brands use crimped-on end caps. Crimped or Banded air bags are prone to popping the end caps out at anything over 100psi and often simply pull the end caps out when the bag is fully extended. BOSS air bags are undeniably the strongest in the automotive industry and exceed any other air bag brands by nearly double. We pride ourselves in looking after everyone. Even if you have had your gear for years we will still look after you because who knows, our next customer could be your friend you refer to us.
