      Product Highlights

      OLD MAN EMU SPRINGS

      When undertaking remote area travel, the need to carry sufficient fuel, water, vehicle spares and safety equipment invariably means that your 4×4 will be fully loaded, placing a lot of strain on suspension components. Combine this with punishing off-road conditions, and the limitations of standard springs soon become apparent.

      Whether it’s coils, leaves or torsion bars, Old Man Emu springs are designed to improve the load carrying capability of your 4×4, allowing you to tackle more challenging terrain with confidence.
