4 inch lift was achieved by linear rate springs using X5K high grade steel tuned to provide compliant ride on road while maintaining off road performance. Trim packers have been included to assist in fine tuning ride height that may be caused by various accessory fitments. 

Shock Absorbers:

A new front Nitrocharger sport shock (60066M) was developed which allows 4” of down travel at the 4 inch lift. Careful consideration was given to maximize the down travel but also to ensure the front drive shaft doesn’t bind and no need for a costly replacement drive shaft (Ref Note page 5). Both front and rear Nitrocharger Sport shocks have vehicle specific valving tuned for optimal blend of ride control and comfort. Shock lengths have been optimized for maximum down travel while retaining factory drive shafts, brake lines and shock mounts. 

Adjustable Forged Track Bar (Panhard Rod):

To center and fine tune the location of the front axle, Old Man Emu has developed an adjustable forged track bar as a replacement to the original. A Hi grade 4140 forged steel adjustable track bar was chosen for it’s superior strength, durability and freedom to optimize design. Note: Track bar bushings come pre installed (not shown in photograph). 

Track Bar (Panhard Rod) Relocation Kit:

A rear Track Bar relocation bracket was developed to address the positioning of the rear track bar. This relocation bracket not only centers the axle but also raises the rear roll center to provide positive rear stability. Old Man Emu engineers have used Design Solid Modelling and FEA to ensure strength and durability. 

Bump Stop Spacer Kit:

A bump stop spacer kit is used to ensure a larger diameter tire is kept off the body work and optimizes shock extended and compressed lengths to allow maximum compression and rebound travel. 

Caster Correction & Driveline Kit:

To achieve a 4 to 5 degree caster correction it only requires 7mm longer arms or a bracket adjustment. For this small shift Old Man Emu has developed an offset washer which is the most cost effective solution. The offset washer is machined steel, fixed position, rectangular in shape and uses factory control arms and provides a reliable, solid solution to return the factory caster angle. A spacer washer has been provided to create clearance between the auto cross member and driveshaft at full droop. The use of this spacer allows maximum travel with the front factory driveshaft. 

Sway Bar Disconnect Kit:

New longer front and rear sway bar links have been developed to correct sway bar alignment due to increased lift. The rear link is the factory style with two ball joints. The front link has an upper ball joint and the lower has a disconnect function using a greasable pin. 

Steering Damping:

The steering damper has been specifically tuned for the Jeep JK to address front end wobbles initiated by anything from worn ball joints to out of balance large diameter tires. 

Brake Line Relocation Kit:

Brake line relocation brackets have been developed to reroute factory brake lines to work with this kits’ extended shock lengths. The relocation bracket provides a cost effective, fitter friendly solution and no brake bleeding is required. A handbrake relocation bracket lowers the brake line mounting position to relieve stress on brake lines resulting from the higher ride height. 

Important Notes:

  • Maximum Tire Size with No Modification : 35"
  • Maximum Tire Size with Fender Trimming and High Clearance Fender Flares: 37"
  • When fitting larger tires, aftermarket wheels with greater offset (less backspacing) may be required to clear sway bar links and control arms.

Additional Required Parts for 2012 - 2014 Models. 

Modifications to the exhaust or driveshaft are required on 2012 and newer models to avoid contact between the driveshaft and exhaust when suspension is at full droop. For Manual Transmission use, 3112JK-24M, For Automatic Transmission use, 3112JK-24F
