The original ARB air locker diff seems to have been around for ever, and in fact, it goes back to the 1980s. It is a phenomenal product, endorsed by off-roaders all over the globe. It seems, however, that the guys at ARB are not prepared to become complacent and have completely redesigned the product. The redesign was undertaken by Daniel Bongard at ARB, and he went right back to basics, as he explains: “We put aside the existing air locker design and started from scratch. Six months of computer-generated concepts involving an original two-piece design, new components and a ‘timed’ gear set.” The result is an astonishing 40 per cent improvement in static torque strength when compared to the original three-piece design. In a market where there are now a number of ‘bargain’ Chinese and Indian air lockers on the market, some of which it seems even claim to be ARB products, it seems obvious to us that cheap is not the answer and if you are in the market for a seriously tough air-locker for your off-roader, then it makes sense to speak to the guys at Arbil, who are the official ARB importers in the UK.
