Step 1: Ensure parking brake is applied. (
Removing the bumper is recommended but not required
) Place jacks at the strong
points on the frame and lift to relieve load on leaf springs (
Note: The higher you can get the truck in the air the easier it will be to
install the new leaf spring later in the installation
). Note: Make sure to mark the leaf spring spacer to ensure proper installation
when installing the lower bag mount . (WARNING: PLACE JACK STANDS NEXT TO JACKS FOR ADDED SAFETY).
Figure #1-3: shows approximate locations of jacks
front dot is on frame or strong points of truck.
Step 2: Remove the shocks and shock mounts from the frame/axle. Next, locate the front leaf mounting point, remove the pin
retention bolts/pin and separate leaf from front mount and rear hanger.
Disassembly ; Drivers side first
Attention: Do all of driver’s side first then move on to passenger side

Step 3: If your truck has a fuel filter near the leaf spring casting or the hood guide, you may need to unbolt and relocate that filter
after the installation of Kit. (
Note: Mount after you install the kit to find the best location
)

Attention: Do all of drivers side first then move on to passenger side Step 1 - 6
Step 1: Leaf spring installation: Set one leaf spring onto the axle, align the leaf spring alignment pin with axle alignment hole
and fully seat the leaf spring. Next, fully set the front pin of the leaf spring in the factory mount. Then use the factory leaf spring
pin clamps to lock the leaf in place. Next, install the rear end of the leaf spring into the factory leaf spring hanger using the
provided shackles and 1/2-20 x 2-1/2 hex bolts, flat washers, and lock washers.

Figure#8 : Bag is bolted to the lower bag mount with the stud facing out. Top bag mount is installed using two bolts “You
will need to use a grinder to smooth the edges of the steering arm to allow for extra clearance”
Figure #7 :Drivers side lower bag mount.
Step 2: Locate the drivers side lower bag mount and provided U-bolts and install onto the axle. Make sure to keep the OEM block
on the bottom to keep correct caster.
Step 3. Locate the 5768 Air bag, upper air bag mount and the lower bag plate. The air bag will bolt onto the lower bag plate with
the 1/2”- 13 x 2” bolt. Do not tighten yet. Now place the upper bag mount to the top of the air bag over the air inlet. (If the
1/2” stud on the top of the air bag has not been cut off, do that now. Use the 3/4” lock washer and jam nut to fasten the
upper air bag mount to the bag. Now, making sure the upper bag mount and lower bag plate are parallel with each other,
tighten the bottom bag bolt to 35 ft/lbs. Now, place the assembly on the lower air bag mount and fasten to the lower air
bag plate with the four 3/8”-24 x 2” bolts and hardware. The next step is to drill 2 holes in each side of the frame to
fasten the upper bag mount. To figure out where to drill the holes in the frame, inflate the air bag to 8” tall. With the air
bag straight up and down (
appearance like a coffee can
) mark the holes in the frame and drill two 9/16” holes in the
frame. Next fasten the upper air bag mount to the frame with the 1/2”-20 x 2” bolts and hardware. (CAUTION:MAKE SURE
NOT TO DRILL INTO ANYTHING ON INSIDE OF FRAME!)
Smooth the
corners of the
steering arm so
they don’t rub
on the bag.
Check for clear-
ance once in-
stall is com-
plete. 3/8”
minimum is
recommended

Step 4. Set air bag at 8” between the mounting brackets. You can use the jacks or manually inflate the bags. Now, install the
upper height control valve mount. Install the height control value facing the gold lever on the driver side towards the front of
the truck using the 5/8”-18 x 11-3/4”Bolts. Next, use the two height control valve linkage kit to connect the two brackets to-
gether using the provided hardware. You can adjust this distance with the holes on the linkage kit to match your truck when at
ride height. (
Note: Make sure the level indicator hole is showing also if you need to shorten this length you are able to cut the
linkage arms to fit your truck.)
Figure #9 shows height control value. Level indicator hole.

Figure #11 Aftermarket steering knuckle shown.
Note: Grind off end of steering knuckle to
allow room for the lower bag mount.
Step 5: To plumb up the height control, find an air source coming off the air tank (preferably not the air brake tank). Use the
supplied 3/8” T fitting to splice into an air line. You will now need to add another 3/8” T fitting so you can run air line to both
sides of the truck. The supply line runs to the height control valve and connects to the 3/8” port marked “SUPPLY” . The oth-
er 3/8” port goes to the air bag. The 1/4” port on the height control valve controls the dump. Supplying pressure to this port
will exhaust the air out of the bags, but not the tanks. Once you get both sides installed and height control valves installed, you
can adjust the height control linkage to set the air bags at 8”

shocks
Step 6: Gabriel shock Installation. Locate the shock, lower height control linkage mount, Locate a 3/4”-16 x 3-1/2” bolt and slide
the lower height control linkage bracket over the bolt. Now insert the bottom of the shock into the mounting tabs and place the bolt
through outside in. Next, fully compress the shock, then extend ~1/2. This should give you ~14” from center of eye to eye. (
This
allows clearance for your shock so you don’t bottom out your shock while lowering the truck
) Then, move the shock in an arc until
you have it where you want it; ~20 deg shock angle or about a finger width space from top of shock to steering column. Once you
have that location you will need to mark it and position the shock mount to match. Drill the two 9/16” holes holding the shock mount
to the frame and finish installing the top of the shock using the 1/2”-20 x 1-1/2” bolts. If you have the kelderman clicker shocks, you
will need to add the spacers between the mount and the ear of the shock. Note: The reservoir needs to be installed clear of any
mounts.

Step 9: Repeat steps 1-6 on passenger side
Step 10: Double check the bolts are tight and make sure the truck is sitting level.
Step 11: Test Drive: It is recommended to have an alignment done within 2-3k miles if the truck pulls either direction. If the truck is not
sitting level it could pull towards one side.
