NORMAL RIDE HEIGHT
: Normal ride height is defined as the
measured distance from the bottom edge of the fenderwell to the center
point of the wheel with the vehicle in the "as delivered condition" (without
camper, tool boxes, unusual load, etc.). This measurement should be
recorded for later reference.
All AIR LIFT kits are designed to be
installed and operated at Normal Ride Height.
1. Jack up front of vehicle or raise on hoist and remove front wheels. If
there is a brake injunction block on the inside of the driver side frame
rail, unbolt and pull valve out of the way. Save existing nuts for later
use (Figure 4).
2. Attach top bracket to sleeve using star washer and nut, leave loose
for later adjustment (Figure 1). LOOSELY attach the lower bracket to
the bottom of the sleeve. Using the provided 1/2” flat washer and the
1/2” HHCS bolt (Figure 1). Note: Bottom brackets are left and right
hand units. Slot faces outside of vehicle.
IMPORTANT -
Your air springs will live much longer if they are not
the suspension limiter in either compression or extension. The air spring
compresses to 2.2" and extends to 10.5". Keeping the minimum required
pressure or a pressure proportional to the load will prevent bottoming out.
The shock absorber is usually the limiter on extension. If this is not the
case, you should consider the use of limiting straps; especially if the vehicle
is used off-road. The maximum inflated diameter of your air spring is 5.6".
You must check to see that nothing is rubbing against the air spring within
this diameter.
FAILURE TO MAINTAIN CORRECT MINIMUM PRESSURE
(OR PRESSURE PROPORTIONAL TO THE LOAD),
BOTTOMING OUT, OVER-EXTENSION, OR RUBBING
AGAINST ANOTHER COMPONENT WILL VOID THE
WARRANTY.
3. Set unit on the leaf spring with the tab of the lower bracket over the
u-bolt (Figure 2).
THE LOWER BRACKET MUST BE OVER
THE U-BOLT NOT THE SPRING RETAINER PLATE.
Attach to the leaf spring with u-bolt, clamp bar, flat washers, and
locknuts, mount and tighten nuts to 20 ft.lbs (Figure 1).
4. Mount the upper bracket approximately 1/4” underneath the brake
line bracket on the frame rail (Figure 3). Using the bracket as a
template, mark two holes on each side of the bracket to be drilled. X
and Y dimensions (Figure 2) should be equal. The sleeve should be
mounted so that it follows the natural arc of the suspension through
its full travel (Figure 1). Remove the upper bracket and drill your four
3/8” holes.
CAUTION: DO NOT DRILL HOLES INTO THE FRAME UNTIL
ANY HYDRAULIC LINES, GAS LINE AND ELECTRICAL
WIRES HAVE BEEN MOVED ASIDE ON BOTH SIDES OF
FRAME RAIL.
5.
NOTE:
If you had a brake injunction block use existing nuts, attach
to bracket supplied. Then using upper bracket mounting hardware
attach upper bracket and brake bracket as an assembly (SEE Figure
4). Install the upper bracket onto frame rail with the provided 3/8 bolts,
washers, and locknuts and tighten 20 ft-lbs (Figure 1).
