VEHICLE HEIGHT MEASURMENTS
This suspension system was developed using a 35 - 11.5 R20 tire with 20” x 9” wheel and a
offset of + 25. If wider tires are used, offset wheels may be necessary and trimming may be
required. Factory wheels can be used but are not recommended with tires over 11” wide. The
stock spare rim can be run in an emergency. Please note that if running the spare factory tire, it
is done for short distances and a speed not to exceed 45mph or damage to differentials may oc-
cur.

Loosen but do not remove the upper and lower control arm bolts.
Remove the upper ball joint from the knuckle. Strike the ball joint
boss on the knuckle with a dead blow hammer to dislodge the taper
from the knuckle. (Fig 5)
Take care to watch the brake lines and ABS for over extension
through the following steps.
Lower the control arm down slowly while holding the top of the
knuckle. Slide the axle out of the hub and actuator being careful not
to damage the actuator. (Fig 6)
Lower the control arm enough to remove the strut. (Fig 7)
Remove the strut assembly from the vehicle.
Mark the top of the strut in correlation to the lower mount. Using a
spring compressor, release the pressure from the top hat of the strut.
(Fig 8)
Remove the top hat and place the preload spacer into the top hat.
Make sure to place between the top hat and rubber isolator. (Fig 9)
Reinstall the top hat with spacer in the same orientation as previously
removed. Torque to 30 ft-lbs.
Install the strut spacer onto the strut using the provided hardware.
Torque to 30 ft-lbs. 2009 - 2013 use spacer that says Right Only on
the passenger strut. 2014 and up are the same spacer for left and right
struts. (Fig 10)
Making sure not to damage the studs, put the lower strut studs into a
suitable vice and rotate the lower sleeve in the strut by pressing on
the top of the strut the opposite direction of the original lean. You are
going to install this strut assembly back into the vehicle 180 degrees
from the original orientation and will need the studs on the bottom of
the strut to lean the opposite direction. (Fig 11)
Remove the upper control arm from the frame. (Fig 12)

Grease the bushings and sleeves and install into the ReadyLIFT con-
trol arms using the provided grease pack. This is a one time grease
install. Install the control arms into the frame using the factory hard-
ware. Do not tighten at this time. (Fig 13)
Install the completed strut assembly into the frame 180 degrees from
the original orientation making sure that the offset of the top spacer is
going in towards the frame and that the stamped word OUT on the
spacer is going towards the outside of the vehicle, using the factory
hardware. Do not tighten at this time. (Fig 14)
Raise the lower control arm up and guide the lower strut studs into
place.
Continue to raise the lower control arm up while guiding the axle
shaft through the actuator and hub bearing. Take special care not to
damage the vacuum actuator as the internal ring is made of plastic
and can be easily broken, resulting in a new part being purchased.
Once the knuckle is high enough, install the boot spacer onto the up-
per ball joint and attach to the knuckle. Use supplied heavy washer
and castle nut for the ball joint. Do not tighten at this time. (knuckle
and ball joint shown off vehicle for clarification) (Fig 15, 16)
***Very important*** To avoid damage to the vacuum actuator,
these steps must done with major caution. Hold the axle and rotate
the hub assembly while pulling outwards on the axle to engage the
splines in the actuator to the splines on the axle. Once the splines are
engaged, the axle will “pop” through the hub assembly. When the
axle is seated you will be able to see the shoulder of the axle through
the hub. If this shoulder is not visible, keep rotating the hub until it
is. The shoulder will be 2mm under the mounting surface of the nut
in the hub when properly seated. Install the axle using the factory
hardware. Torque the axle nut to 20 ft-lbs, and the upper ball joint to
85 ft-lbs. (Fig 17, 18)
Install the tie rod end to the knuckle using factory hardware. Torque
to 110 ft-lbs. (Fig 19)

have rubber or urethane components to insure proper torque. Torque wheels to factory specs.
Move vehicle backwards and forwards a short distance to allow suspension components to ad-
just. Turn the front wheels completely left then right and verify adequate tire, wheel, brake
line, and ABS wire clearance. Test and inspect steering, brake and suspension components for
tightness and proper operation. Inspect brakes hoses and ABS lines for adequate slack at full
extension.
