ARB 4059 Old Man Emu Coil Spring

The ARB 4059 is an Old Man Emu (OME) coil spring engineered for superior off-road performance and load-carrying capability. Designed and tested in the demanding Australian Outback, OME coil springs are specifically manufactured to integrate seamlessly with ARB's BP-51, MT64, and Nitrocharger shock absorbers for a fully optimized suspension system.

Key Features:

• Precision-wound using CNC mandrels for consistent specifications and identical spring characteristics
• Fully shot-peened construction to reduce stress and enhance spring life
• Scragged to eliminate subsequent spring sag and maintain ride height under load
• Load-tested to ensure compliance with required specifications
• Original equipment coil end design for proper fitment
• Variable or constant rate design depending on application for optimal ride comfort unladen and loaded

Old Man Emu coil springs are engineered to provide noticeable improvements in vehicle performance, load-carrying capacity, and control characteristics across all terrain. When paired with corresponding OME shock absorbers, these springs deliver a fully integrated suspension system designed to handle the rigors of remote travel with heavy loads including fuel, water, equipment, and accessories. Backed by ARB's 3-year warranty with no mileage limits.
