ARB 63109 Old Man Emu Nitrocharger Plus Rear Shock Absorber

The ARB Old Man Emu (OME) Nitrocharger Plus 63109 is a premium rear shock absorber engineered to deliver confident performance across a wide range of driving conditions — from daily commutes to demanding off-road terrain. Combining off-road dependability with smooth on-road driving, the Nitrocharger Plus line represents an ideal balance of capability and comfort.

Each Nitrocharger Plus shock absorber is developed with vehicle-specific valving, carefully matched to the OME spring range it is designed to complement. Ride Control Engineers tailor the damping characteristics to accommodate different loads, lift heights, and accessory configurations, ensuring optimal performance regardless of how the vehicle is set up.

Key Features:

• Vehicle-specific valving — tuned to match OME coil springs for a responsive, controlled ride
• Heavy-gauge steel tube — 23% more effective than standard tubing for superior durability
• Six valving discs — provide maximum ride quality and handling performance
• High-performance fluid formula — engineered to resist fade and aeration under demanding use
• Induction-hardened chrome piston rod — purpose-built for 4x4 touring and heavy loads
• Triple-lip oil seal — virtually eliminates contaminant intrusion for long service life
• Impact-resistant dirt shield — protects internal components from off-road debris
• High-quality polyurethane bushings — extend shock life and reduce noise and vibration

The Nitrocharger Plus is designed to excel when carrying heavy loads, towing, or navigating challenging off-road landscapes. When paired with the appropriate OME vehicle-specific coil springs, it delivers a customized, confidence-inspiring ride on any terrain.
