Black Diamond Jeep Wrangler & Wrangler Unlimited JK Lift Kits
4WD 2 and 4 Door Models, Including JK Rubicon |
|
|
The JK 4-link suspension design is much like that of its
predecessor, the Wrangler TJ series. Both Wranglers utilize track
bars to locate each axle left-to-right, and four-link arms to locate
the axles front-to-rear. The primary difference is the JK's longer
factory link-arms. Black Diamond offers a 2" coil spacer lift, and a
3" replacement spring system that features vehicle-specific coils
for 2 and 4-door models. |
Black
Diamond® 2" Jeep JK Suspension Lift System
Thicker coil spring isolators replace the factory isolators installed on
top of the stock coil springs. By retaining the factory springs you are
assured of factory ride quality, and a true 2" of lift. The various new
JK models are offered with 22 different coil spring rates, dictated by
how they are equipped from the factory, meaning there are slight
variations in ride quality and lift height when replacement springs are
used. New compression travel-stop spacers are included. Replacement
shocks are not required, although new Black Diamond AT Series shocks
improve control plus allow an additional 2" of extension travel.

Black
Diamond® 3" Jeep JK Suspension Lift System
The JK family uses 22 different factory coil springs, each with a
slightly different rate, dictated by how the JK is equipped. New Black
Diamond front / rear coils provide the lift. The largest jump in spring
rate is from the 2 to 4-door model so we offer a heavier rated rear
spring for the 4-door. Lift height can vary slightly (plus / minus up to
3/8") depending on your factory spring rate.
As the JK is raised, track bar angle increases and when lift height
exceeds 2" bar length becomes an issue. Bar bind causes the chassis and
axle to continuously "tug" against each other resulting in uneven ride
height (side-to-side), chassis / frame misalignment and "roll and yaw".
Front correction is accomplished via a new adjustable track bar. This
route is preferred, as opposed to using a relocation bracket, since the
bar's arc-of-travel must remain in-sync with the drag link's
arc-of-travel or steering wheel "kick" will result. A relocation bracket
is used on the rear axle since there are no steering geometry issues.
The stock JK has no provisions for front caster angle realignment, which
is required at this lift height, so Black Diamond provides new alignment
cams. Compression travel is controlled via new Urethane stops while new
AT Series shocks improve control and restore full extension travel. The
lift system also includes longer sway bar links with factory style,
greasable tie-rod type upper ends, front / rear brake hose relocation
brackets and emergency brake cable brackets... nothing is left
unattended.
Superlift options include upper and lower Rockrunner series
axle-to-frame link-arms, constructed of .188" wall thickness DOM tubing,
for increased articulation. Urethane link eye bushings at the axle
improve control while steel-encased rubber bushings at the frame ends
prevent noise and vibration transfer. Other options include front sway
bar quick disconnects, a replacement steering stabilizer, diff cover
protectors and more.
