ARB is one of those companies that are always improving. Innovation is, and always has been, the key to ARB’s success. Even though they are Australia’s #1 manufacturer and distributor of off-road accessories, as well as a major player in the global market, they never seem to be satisfied with their current product selection. Every year ARB invests substantial capital into product development and testing. New products spend years in development and go through rigorous testing and safety procedures. Basically, nothing leaves the ARB warehouse unless it's 100% solid, reliable, durable, and stylish.Rear Differential Cover by ARB.
