Adding weight to your vehicle, combined with poor off-roading road conditions, can create a need for upgraded suspension to your vehicle. Old Man Emu 4x4 Suspension by ARB is designed with the relationship between vehicle weight and performance in mind. The emu is a large, flightless bird. While running, its legs absorb the impact while allowing its body to remain motionless, even while running over different terrains. The Old Man Emu shocks and suspension systems strive to achieve this same type of absorption power. They include carefully engineered spring and shock combinations that are designed to create a smooth vehicle ride, handling, and control, even with different loads and weights. ARB invests heavily in testing to ensure that your vehicle not only performs practically, but is able to work with modern vehicle safety features such as electronic stability control.
