The ARB Old Man Emu 4" suspension lift kit for the Jeep Wrangler JK is the serious off-road upgrade for JK owners who want maximum capability without sacrificing on-road ride quality. At 4" of lift, the JK can run 35" tires with proper clearance, dramatically improving approach, departure, and breakover angles for technical trail use. Unlike budget lift kits that simply add height, the OME 4" system is a fully engineered, matched suspension package — tuned specifically for the JK's weight, geometry, and intended use.

Developed and proven on Australia's most punishing outback terrain, OME suspension components are tested to a standard that most aftermarket brands cannot match. The result is a 4" lift that rides better than many 2" kits from lesser brands — controlled and comfortable on the highway, articulate and capable on the trail.

Kit Includes

• Coil Springs: Front and rear high-grade, progressively wound springs designed to handle additional accessory weight.
• Shock Absorbers: Four Nitrocharger Sport shocks with vehicle-specific valving.
• Track Bar & Brackets: A forged adjustable front track bar and a rear track bar relocation bracket to keep axles centered under the vehicle.
• Steering Damper: An OMESD48 steering stabilizer with a relocation bracket to handle larger tires.
• Sway Bar Disconnects: Front sway bar quick disconnects and extended rear sway bar links for increased off-road articulation.
• Geometry Correction: A caster and driveline kit (typically using correction washers or brackets) to maintain proper alignment.
• Protection & Clearances:
  • Bump Stop Extensions: Front and rear spacers to prevent over-compression.
  • Brake Line Relocation: Brackets that move factory lines to accommodate the extra travel without needing to bleed the brakes.
  • Trim Packers: 10mm spacers to fine-tune ride height if your Jeep is uneven due to heavy bumpers or winches. 
    

Notes:

• Driveshafts: For 2012+ JK models, an aftermarket front driveshaft or exhaust spacers are often required to prevent the factory driveshaft from contacting the exhaust at full suspension droop.
