ARB BP5160039 Old Man Emu BP-51 Bypass Rear Shock Absorber

The ARB BP5160039 is an Old Man Emu BP-51 high-performance bypass shock absorber designed specifically for lifted Nissan Patrol applications (1987-2016) with 3-4 inch lift kits. This rear-position shock features advanced internal bypass technology with a 51mm bore diameter and remote reservoir design for exceptional on-road comfort and off-road control.

Key Features:

• Internal bypass design with kidney bypass ports for position-sensitive damping
• Independent external compression and rebound adjustment for custom tuning
• 6061 T6 aluminum construction with Type 3 hard anodizing for heat dissipation and corrosion resistance
• High-pressure nitrogen reservoir with aluminum anodized floating piston
• Adjustable spring preload and ride height capability
• Impact-resistant replaceable shaft guard
• Quality oversized rubber bushings and large Teflon-lined spherical bearings
• Vehicle-specific application utilizing existing mounting locations
• 51mm bore diameter for increased oil capacity and thermal management

Developed, tested, and manufactured entirely in-house by ARB's Old Man Emu engineers in Australia, the BP-51 delivers class-leading ride customization that can be tailored to specific vehicle setups and trip requirements. Unlike most adjustable shocks that only offer compression adjustment, the BP-51 provides independent control of both rebound and compression for unmatched versatility.
