ARB 5204K Old Man Emu BP-51 Bypass Shock Absorber & Upper Control Arm Suspension Kit

The ARB Old Man Emu BP-51 Kit (Part# 5204K) is a complete front and rear suspension upgrade featuring ARB's premium BP-51 bypass shock absorbers paired with an Upper Control Arm (UCA). Engineered for serious off-road performance without sacrificing on-road comfort, the BP-51 series represents the pinnacle of Old Man Emu suspension technology.

The front shocks in this kit provide 2.5 inches of lift and are valved to support a spring rate of 0–330 lbs, while the rear shocks deliver a 1.5-inch lift with a 0 lb spring rate configuration, making them ideal for use with complementary coil springs. The included Upper Control Arm corrects suspension geometry when lifting, reducing wear and improving caster angle for better handling and tire life.

Key Features:

• BP-51 Bypass Technology – Internal bypass channels provide a compliant ride over small bumps while offering progressive resistance through the full stroke for heavy off-road use
• Front Lift: 2.5 inches with 0–330 lb spring rate compatibility
• Rear Lift: 1.5 inches with 0 lb spring rate (coil spring dependent)
• Includes Upper Control Arm (UCA) – Restores proper suspension geometry for lifted applications
• Fully adjustable damping – External adjustment allows tuning for load, terrain, and personal preference
• Heavy-duty anodized aluminum body resists corrosion and dissipates heat during extended off-road use
• Nitrogen-charged, twin-tube bypass design for consistent, fade-free performance
• Rebuildable and serviceable for long-term reliability
• Designed and tested to Old Man Emu's rigorous Australian outback standards

The ARB OME BP-51 5204K kit is the ideal solution for enthusiasts seeking a serious lift and off-road capability upgrade while retaining ride quality on daily-driven vehicles. Whether tackling trails, overlanding, or simply improving capability, this kit delivers professional-grade suspension performance.
