I do not accept returns of used parts. Returned kit must be unused and include the original box and/or packaging with all parts included. A 20% restocking fee will be applied to all returned kits. A PayPal credit will be issued after inspections of returned item. Buyer pays for return shipping. Make sure you purchase the correct kit for the correct application.

BOSS does not copy others. To begin with BOSS does not trust the others to get it right and more importantly the others don’t have anything to copy. BOSS is 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. As such BOSS have the widest range of applications for Australian and now USA markets and continue to lead the way in quality offerings. BOSS sells to mining and heavy commercial operators, agricultural contractors and farmers, tradesmen, fishermen, campers, and people who tow trailers.

BOSS Air Suspension air bags are manufactured in the BOSS factory with their own machines to their own exacting standards and specifications. BOSS strongly believes it's the only way of maintaining strict control over their bags. Many other companies piece together air bag kits by sourcing their air bags from various suppliers having no control over the consistency or quality over generic bags. And that's why their bags are not branded. With a BOSS Air Bag Load Assist kit, you can run very soft at low pressures 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 pounds per bag = 5000 pounds.

BOSS can supply each individual component separately if for whatever reason you need a new part, bearing in mind you have a long warranty anyway.

BOSS air bags are undeniably the strongest in the automotive industry and exceed any other air bag brands by nearly double. BOSS kits have been around for over 10 years and in that time literally thousands have been fitted. From this we know we can stand by our 5-year warranty confident that you are going to be very happy with your purchase.
