Loking at getting a used ARB winch bumper for my Disco 1

How can I tell if it's Air Bag approved?

i believe the difference was the two mounting points either had solid crush cans or the accordian shaped crush cans. from what i remember the accordian style was meant for airbags but i cant confirm.

also there has been a lot of discrepancies regarding the strength of the accordian style and how they can possibly deform when used with winching, some owners welded flat steel across the top of the ribs to strengthen it.

I would think as long as its the correct model for your Disco then all should be OK, according to the ARB website;

Bull Bars/Bumpers & Tire Carriers

Unlike most brush guards and grille guards, ARB bull bars incorporate a fully engineered mounting system which completely replaces the standard bumper. During the design process, careful consideration of numerous factors ensures it will properly serve its purpose.

ARB manufactures winch compatible bull bars and Sahara bars for most 4WDs - they provide the quality protection you expect, without compromising design and aesthetics.

AIR BAG COMPATIBILITY

With an air bag equipped 4x4 it is essential that the vehicle's crush rate and air bag triggering is not altered when a bull bar is installed. To ensure compatibility, ARB assesses each vehicle's frontal crush characteristics and replicates the crush rate into the design of each air bag compatible bull bar and its mounting system. This method enables engineers to achieve maximum possible vehicle and passenger protection without affecting the crash pulse. ARB has invested heavily in vehicle crash barrier tests to validate the performance and compliance of its air bag compatible bull bars, and as a consequence, our bars offer a far greater level of protection than most standard brush guards and grille guards.

Please note that a few of the bumpers for older model vehicles are not air-bag compatible, refer to the Vehicle Application Guide for confirmation.Read more at
