Rubicon lockers are plenty reliable. All the stories you hear about the failures are based on the fact that Jeep ships more lockers in Rubicon models than all other manufactures of aftermarket Jeep lockers combined and then probably some multiple of that. Jeep ships 50,000-80,000 lockers per year in the USA which would be about 55-88 million in revenue if they were all ARB lockers. ARB's entire business revenue in the United States is only 28 million dollars, and this includes OME, bumpers, diff covers, awnings, tents, refrigerators, air compressors, etc. I would imagine the diff lock portion of their business is only 10-20% of their revenue which would be 5000 lockers sold per year in the united states to a wide variety of vehicles, not just Wranglers. Let's say half the lockers are sold to Wrangler owners, and the other half to Land Cruisers, 4Runners, FJ Cruiser, pickup trucks and vintage 4x4s. 2500 lockers per year is about what is needed for one week of Rubicon production, which means every complaint on wrangler forums about ARB lockers is equivalent to 52 complaints on Rubicon lockers.
