ARB lockers are tough lockers. They have a 4 pinion style carrior which is much stronger than the stock one. I also like the fact that you have control of it, unlike the Detroit which is just horrible(DANGEROUS) for on-road use. The down side is that the ARBs only last for 3-4 years before they just stop working. Detroits last forever. I have had several problems with my ARB locker on my LR(when it works...it works!), but it seems like you guys have not had any problems with yours, have you? I know of a lot of people that have had problems with their ARB's.
