It is normal to hear a slight audible clicking noise during compression and rebound strokes in the B8 8112 shocks, most notably during low velocity events. This is due to the internal pistons engaging each other creating the position sensitive compression and rebound zones.

B8 8112 shock installation procedure:

A. Remove the existing shock module from the vehicle following all procedures in the vehicle manufacturer’s service manual. Save the lower shock bolt and nut as they will be used later.
B. Before installing the B8 8112 shocks on the vehicle check if they are set at the desired lift height. The pre-set lift heights are different for each drive-type, engine, cab, bed, and year range. Use the tables below to determine if the pre-set lift height is what is desired:

4WD V6,

Double Cab, 6’ Bed

2016+| 2005- 2015
1.4” lift| 1.9” lift

C. If the lift height listed above is not what is desired, proceed to Step D. Otherwise, go to Step K.
D. Break the spring seat lock ring loose with the supplied spanner wrenches. Refer to Figure 1 on the next page.
E. Note the clocking of the lower mount relative to the studs on the upper mount (important for reassembly).
F. Using an appropriate spring compressor, compress the spring until it can be rotated freely by hand. Then, spin the spring seat up or down depending on what the desired lift height is. Note that the right side (passenger) should always be approximately 5/16” lower than the left side (driver) to compensate for the inherent vehicle lean. The following tables show what the allowable lift height ranges are for each truck configuration and give a few points of reference for the relationship between the amount of exposed thread and the estimated lift height. They are listed for stock weight vehicles.

** Lift heights indicated are typical. Actual lift height is influenced by which factory suspension the vehicle is equipped with and its condition; optional equipment and accessories on your vehicle, and other vehicle modifications such as replacement coil springs, wheel and tire combinations, etc.
Modifying/lifting the suspension to your vehicle may raise its center of gravity and may make it more susceptible to loss of control and/or rollover, which may result in death or serious injury. We strongly recommend that you offset the loss of rollover resistance as much as possible by increasing tire track width, and that you equip the vehicle with a functional roll bar and cage system.
Wear seat belts and shoulder harnesses at all times, and avoid situations where a side rollover may occur.
NOTE: if you exceed the recommended spring seat adjustment range (exposed thread dimension) for your vehicle, make sure to measure the shock at ride height as shown below after the install. This is needed to ensure there is at least 2” of droop travel from static ride height and so the stiffer rebound zone is not being engaged at ride height.

G. Before finalizing the desired lift height, position the elongated hole in the spring seat so it will face inboard once installed on the vehicle.
H. Once the desired lift height is set, tighten lock ring against spring seat using supplied spanner wrenches.
Torque lock ring to spring seat 37 ft-lb (50 Nm).
I. Rotate the lower shock mount so it is aligned with the upper mount studs as noted in step E.
J. Slowly release the spring compressor.
K. Disconnect the sway bar bolts holding sway bar to frame (2 per side) with a 14mm socket and drop the  sway bar as shown in the images below. Save these bolts as they will be used to mount the new sway bar spacers later.

L. Install the shocks onto the vehicle as shown in the image below. Use the 6 supplied nuts and a 15mm socket to attach the upper mount (3 per side, BOM item #4). Leave reservoir hanging temporarily. Torque supplied upper mount nuts to 33 ft-lb (45 Nm). M. Attach the lower shock mount with the OE shock bolt and nut that was removed in Step A (1 per side). Torque lower OE shock bolt and nut to service manual specification.
N. Apply non-permanent thread locker on the end of each of the screw threads of the OE sway bar bolts that were removed in Step K. Then place these bolts (2 per side) through the counterbored holes in the supplied sway bar spacer (BOM item #6) and thread into the threaded holes in the frame using a 14mm socket as shown in the image below.
Torque OE sway bar bolts to service manual specification. O. Apply non-permanent thread locker on the end of each of the screw threads of the 4 supplied M10 Flange Head Cap Screws (BOM item #3). Then place these screws (2 per side) through the holes in the OE sway bar bracket and thread into the threaded holes in the supplied sway bar spacer with a 15mm socket as shown in the 2 images below.
