be parallel with the ground. The bracket will angle the
height sensor arm inboard to allow the arm to swing
freely throughout the suspension travel. Ensure the
extension arm does not interfere with the shock.
FOR CREW CAB: The height sensor brackets should
be installed just behind the bed mount brackets
approximately halfway up the frame. This should be
above the front vehicle suspension mount.
FOR QUAD CAB/REGULAR CAB: The height sensor
brackets should be installed above the front vehicle
suspension mount, approximately halfway up the
frame. This is about 10 inches back from the bed
mount bracket.
While holding the height sensor bracket in place, use
(2) 10-16 x 3/4 self tapping screws to attach the height
sensor bracket to the vehicle on each side. NOTE: 7/32"
holes and machine screws (not provided) can be used
in place of the self tapping screws.
Attach the height sensor to the installed bracket using (2) M5-0.8
X 8mm machine screws on each side. See Figure “D”.
STEP 5: INSTALL THE AIR SPRINGS
The bottom of the air spring assembly has a threaded hole that must
face the rear of the vehicle and the air fitting on the top should face
the front of the vehicle. Place the air spring assembly on the lower
axle mount. Using the 1/4"-20 x 3/4" button head screws provided,
secure the bottom of the air spring assembly to the lower mount. See
Figure “H”.
Place the top plate on the top side of the upper mount. Unroll the
air spring, by pushing the top of the air spring up, until the air spring
assembly reaches the upper mount on the vehicle. Place the top plate
above the vehicle’s upper spring seat by aligning the top plate to accept
the threaded studs from the air spring assembly. Hand tighten the 3/8"-
16 nuts (serrated face) to the top plate. DO NOT ALLOW THE AIR
SPRING SLEEVE TO TWIST. Once the air fitting is correctly aligned
towards the front of the vehicle and you have ensured the sleeve is not
twisted, tighten the 3/8"-16 nuts See Figure “H”.
Reinstall the shocks on both sides of the vehicle.
STEP 6: PREASSEMBLE THE COMPRESSOR, VALVE
BLOCK, AND ECU MOUNT
See Figure “U” for bracket layout. The mounting plate for the com-
pressor, valve block, and ECU has predrilled holes to accept each
component. All components that are mounted to
the plate should have the head of the bolts on the
back side of the plate for clearance.
The compressor mounts in the lower left side with
the intake pointing left. Use four 10-32 X 1" machine
screws with washers and nylock nuts to mount to the
plate. Attach the compressor tee fitting to the check
valve on the output side of the compressor. Attach the
pressure switch to the compressor tee. See Figure
“I”. The ECU mounts directly above the compressor
with two, 4-40 X 5/8” machine screws and nylock nuts.
See Figure “I”.
Before mounting the block, install the 1/8 NPT
straight air fittings into the ports labeled ‘LR’ and ‘RR’.
Tighten to engage the orange thread sealant. Install
the 1/8 NPT elbow into the port marked ‘IN’. Hand-
tighten, then turn an additional 1/2 turn with a wrench.
The valve block should be oriented so that the exhaust
port points to the right and the inlet is down. Use the
1/4"-20 X 1-3/4" bolts with washers and nylock nuts
to secure the block in place. See Figure “J”.
