INSTRUCTION MANUAL BEFORE
Installation of Hotchkis Rear Shocks
1
Raise the Truck
Raise the vehicle by using a drive-on alignment rack. Securely block the front
wheels of the vehicle.
2
Remove Old Shocks
Remove your old rear shocks by unfastening the top and bottom nuts & bolts. You may
discard the shocks and hardware.
3
Support the Trailing arms
Using the lifting jacks on your lift, support the rear trailing arms under the coil
springs. Jack the truck up until the rear wheels just begin to raise off the lift
surface.
4
Remove Stock Shock Mounts
Both the upper and lower shock mounts will be replaced. Using an air chisel, cut
off the rivet heads securing the upper mount to the rear frame. Completely remove
the rivets.
Next, remove the lower shock mounts by undoing the large u-bolts holding the rear
axle to the trailing arms. The lower mounts should be loose from the arms. You may
discard the upper and lower mounts.
5
Install Hotchkis Shock Mounts
Install the Hotchkis upper shock mounts as shown in the picture. Hardware is
provided for mounting to the existing rivet holes.
Install the lower shock mounts in the same manner as stock removal. Please see
picture for proper orientation and placement of side specific brackets. Secure the
lower shock mounts using the original u-bolt hardware. (Please call Hotchkis if you
would like to purchase new U-bolts P/N: T1734) Fully tighten hardware at this
time. (Tip: It is recommended that you apply anti-seize compound on the U-bolt
threads before reinstalling the nut.)
6
Install Hotchkis/Bilstein Shocks
With the mounts in place, install the shocks by starting with the lower mount.
Install the following hardware in the order shown in the picture. Leave this
hardware loose until you get the upper mount in.
Installation of Hotchkis Track Bar
New hardware is also provided for the upper mount. The Hotchkis upper mount has 2
adjustment holes. The hole toward the rear is the stiffer shock setting. Once the
shock is in place, fully tighten all shock hardware.
Lower the lifting jack from the trailing arms and you are now finished with the rear
shock installation.
1
Remove Stock Track Bar
Remove the stock track bar by undoing the left frame mount bolt and the nut
attaching the track bar to the rear end housing. Retain the frame mount hardware
for reinstallation.
2
Install Track Bar Mounts
Grab the driver side track bar mount and install it on the existing frame mount.
Use the original bolt and nut. Do not fully tighten this bolt yet.
rd
Take the shorter adjustable bar and install it on the 2nd or 3
hole on the driver
side mount bracket. Grease bushing surface with provided lube.
Attach the passenger side frame bracket to the bar using the included hardware.
Adjust the length of the support bar so that the driver side bracket is vertical and
the passenger side bracket mates to the frame rail properly.
Mark the passenger side frame rails to record all of the holes for the bracket.
(Important Note: Make sure the bracket is not too far towards the rear, which may
cause the rearward bolts to interfere with the frame support. Frame support held in
by rivets shown in above pictures.)
Drill the 6 holes using a 7/16” drill bit. (Tip: Drill pilot holes with a smaller
1/8” bit first) Watch out for any fuel lines inside the frame rail!
Once the holes are drilled, use the provided 3/8” hardware to mount the passenger
side bracket to the frame. Fully tighten this hardware and the driver side
hardware.
Next use the longer adjustable bar and mount it to the driver side frame bracket and
the passenger side lower shock mount bracket. Choose the holes that allow the bar
to be as low and as level as possible based on your ride height. You will need to
adjust the length of the track bar to match the holes up. Again, apply the supplied
grease to bushing surfaces.
Once all of the suspension members are in place, measure the distance between the
inside of the rear tires and the wheel wells. Adjust the track bar (lower one) in
or out to equalize the tire gap. Once adjusted, fully tighten all of the hardware.
You are finished with the Hotchkis rear suspension system!
