Old Man Emu Part #: OMEJK4
Description
Take the guess work out of ordering your Old Man Emu customized suspension system by ordering this complete kit with a single part number in a single box.This complete Old Man Emu suspension kit is engineered to improve ride and handling while providing approximately 4 inches of suspension lift to a stock Jeep® Wrangler JK. Kit comes complete with all the necessary installation parts including coil springs, steering stabilizer and the new Nitro Sport Shocks.
Details

Springs:
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.

Steering Damper Relocation Bracket:
For all LHD Jeep Wrangler JK models, a steering stabilizer fit kit
has been developed to relocate the stabilizer above the tie rod. By
repositioning the stabilizer, it is less vulnerable to damage as it’s no
longer the lowest part of the front suspension.

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.
