ARB 5203K Old Man Emu BP-51 Bypass Shock Absorber Kit - Front 2.5in/0-330lb & Rear 1.5in/0lb

The ARB Old Man Emu BP-51 Bypass Shock Kit (5203K) delivers race-proven, remote-reservoir bypass shock absorber technology engineered for serious off-road performance. Featuring fully independent compression and rebound adjustment, the BP-51 system allows drivers to fine-tune their suspension precisely to load conditions and terrain without the need for special tools.

This kit includes front shocks with 2.5 inches of lift and a 0–330 lb spring rate range, paired with rear shocks providing 1.5 inches of lift. The BP-51's remote reservoir design dramatically increases oil and gas capacity compared to conventional monotube shocks, reducing heat buildup and maintaining consistent damping performance during extended off-road use.

Key Features:

• Fully independent compression and rebound damping adjustment
• Remote reservoir design for superior heat dissipation and fade resistance
• Front: 2.5-inch lift with 0–330 lb coil spring rate compatibility
• Rear: 1.5-inch lift configuration
• High-flow piston for improved small-bump sensitivity and ride comfort
• Digressive valving delivers a compliant on-road feel with progressive off-road control
• Hard-anodized aluminum body for corrosion resistance and long service life
• Nitrogen-charged monotube design prevents cavitation and aeration
• Designed and engineered by Old Man Emu (OME), an ARB brand

The BP-51 series is Old Man Emu's flagship shock absorber, purpose-built for 4WD enthusiasts and overlanders who demand maximum performance in the most demanding conditions. Whether navigating rock crawls, high-speed desert runs, or heavily loaded touring setups, the ARB 5203K provides the tunability and durability to match.
