Load Assist air bags sit between the chassis and axle to assist with carrying loads. Just add more air until you reach the ride height you want no matter how heavy your load. And when you dont have a load just let the air out of the bags and you are back to havinging soft suspension and a comfort ride. If you get heavy springs you cant go back to soft when unloaded and most people find their heavy springs are still not heavy enough anyway. If you see yourself in this predicament then you really should consider air spings to assist your old suspension. Here are just a few examples.. Slide on campers – heavy when the camper is on but light when the camper is off. People towing vans and trailers need air springs when they are towing but their factory suspension is ideal when they are not. Some contractors cart fuel, water firewood and they get heavily loaded but light when empty. Tradies cart different tools and equipment to different jobs. With air spings a. Ll of these guys can change the load capacity of their suspension to suit their needs. Make towing safer by loading more weight to the front of the van or trailer and just pump up the bags a bit to handle the bit of extra weight on the draw bar. When fitting these bags you are not changing your old suspension nor increasing your GVM allowances. When carrying a load the typical pressure range is 25psi to 50psi. The good thing about air bags is just keep adding more air until you reach your desired ride height and comfort no matter the weight. You can’t hurt the bags because they can go to like 800 psi but here we are only talking the sorts of pressures you would run in your tyres. Speaking of tyres the air bag valves are just normal tyre valves. They are rated to still be effective with up to 2.5t over the back axle which in most cases is way more than you should be carrying and just goes to show the bags are up for what ever you throw at them. Some air bag kits like those that go inside coils can only offer 450 Kg which is nothing on these. You can not hurt these air bags. There is no maximum pressure because even industrial compressors can not reach the lofty heights of 800 to 1000 psi where these were made. Sticks, stones and sand will not hurt them. The rubber in these bags is heavier than the rubber in your tyres – we have people who live on cattle stations and have horrid corrugated gibber roads and they never have issues. There is no rubbing parts and they will not wear out. They can see out your car’s useful life no matter the age or distance. The Air Bags replace and become your new bump stop. Even if you have no air in them the bag compresses and the sidewalls are such that you still have a rubber bump stop. The end plates are still an inch apart on full compression so they do not strike each other. As such we dont need internal bump stops. It’s ok to run these flat. Note that because they are your bump stop it’s also good to have a few pound in the bags even when not carrying a load to cushion your bump stop and it makes for a more sporty ride too. Here’s where Air Assist Suspension lead the way and beat the other brands… Air Assist brackets are 100% made in Australia. Other brands make their brackets overseas and not only is that unaustralian but when they run out they can run out for months. It also means they cat customise brackets for customers. Air Assist has been approved and licensed to use the Made in Australia logo. Air Assist have a massive 4WD knowledge base and their kits do not fall short. Some other brands claim to suit 2 lift when they barely reach standard height. At Air assist, we offer height options and can even taylor make custom kits. Air Assist kits use heavier steel components. The end plates are 6mm steel rather than 5mm and we dont make do with C channel like others but instead use 3mm RHS where possible for added strength. And heavier steel means we crank up the welder and get deeper stronger welds. The manufacture and design of Air Assist kits has been guided by automotive engineers who not only specify materials and designs but specify where and how to weld so as not to compromise the integrity of the steel. The others clearly got that wrong as they weld across the arms instead of with them in their brackets. Others use imperial 1/4 air line and NPT threads whereas Air Assist use metric 6mm and BSP threads… Means parts are readilly replaceable anywhere if needed while on a big trip. Air Assist air fittings come pre-fitted to end plates with high pressure gas sealant. Air Assist kits come with an extra meter of air line over others. And its high flex, super strong and meets all the safety standards. Every bolt and washer in an Air Assit kit is stainless steel so wont rust. Air Assist kits can be run flat and still the end plates will not strike each other. You still have a cushioned bump stop and you dont chew the bags out from the inside. Air Assist Load Assist Kits include everything needed to fit and be operational. 2 Air Bags with alloy rings. Top and Bottom mounting plates using 6mm plate steel. 6 metres of 6mm poly air line. 1/4 BSP push to connect fittings in end plates to the 6mm air line. 2 x tyre valves for inflation and deflation – one per bag. Working diagram and instructions. These bags will not be harmed by over stretching them. They clamp to the end plates and the worst thing you could do is pull the bag away from the clamp so just undo them, reposition and do them up again. But we can make sure you get the right length brackets and bags so your shocks prevent over stretching. You can protect your investment with this kit – when you upgrade your vehicle in almost all cases you can keep your old bags and just get a new set of National brackets to suit the new rig. There is no drilling cutting or welding required. These kits just bolt in using your suspension mounts and either use the old bump stop mounts or clamp onto the chassis. Just a normal socket set is all you need by way of tools and anyone can do it in about an hour – you dont even need a hoist. Here are a few pics demonstrating the preparation and effort gone into the National brackets over other brands… National get the one piece laser cut and folded rather than tack a heap of separate parts together.
