DO NOT inflate the air suspension system until it is installed. Inflation of the air suspension system before
both ends are supported by the motorcycle’s frame and/or appropriate suspension components may result in serious
personal injury and/or damage to the air suspension system. The maximum recommended air spring inflation pressure
is 100 psi.

GENERAL INFORMATION:
Reading this manual signifies your agreement to the terms of the general release, waiver of liability, and hold harmless agreement, the full text of which is available at
Avoid damage to air lines and electrical components.Removal and installation is only to be performed by fully qualified personnel.
Damage to the motorcycle and air suspension system can be incurred if work is carried out in a manner other than
specified in the instructions or in a different sequence.
Each owner or installer is unique, therefore installation of this system can be done many different ways. The mounting locations
of the compressor and inflation switch are suggestions by our engineers. If proper wiring guidelines and instructions are
followed, relocation of the compressor or switch will neither affect the system operation nor void your warranty.
Adjust air shock pressure as required for desired ride quality to maximize the benefits of your system. Excess pressure will result
in a firmer ride, too little pressure will allow the suspension to bottom out.
To avoid the possibility of short circuits while working with electric components consult your owner's manual on how to
disconnect your battery.
Refer to the Owner’s Manual for the bike and instructions for the motorcycle lift for all correct lifting procedures. It is also
recommended that you protect any chrome or painted surfaces that may be damaged during lifting, removal or installation
process.
The Arnott accessory kit K-2850 is necessary when installing Arnott Ultimate Ride Kits MC-2904, MC-2905, MC-2906 and MC-2907 or Smooth Ride Kit 9048 kit for 2014-Present Harley-Davidson® Touring motorcycles equipped with Harley-Davidson’s Saddle Bag Guard Rails (P/N 90200561) or 2014-present CVOTM Touring motorcycles with O.E. speakers in the saddle bags. This kit includes CNC Machined aluminum spacers and additional hardware that was designed to securely adjust the placement of the air suspension compressor so that it will not interfere with the Bag Rails or touch the CVO Speaker connection harness.

AIR SHOCKS REMOVAL
Use a solid, level surface to position the bike on a motorcycle lift and use all recommended safety techniques.
Lift the bike so the rear wheel is just slightly off the ground.
1. Remove the air hose from the factory
air shocks. To disconnect the air line, push
down on the red plastic ring while pulling
out on the air line at the same time. (FIGURE 1)
2. Loosen and remove the upper and lower
shock bolts. (FIGURE 2)
3. Carefully remove factory air shocks
from the rear suspension.. (FIGURE 3)
4. Remove the factory air line and valve. (FIGURE 4)
AIR SHOCKS INSTALLATION
Tighten all nuts and bolts to manufacturer's specifications during the installation process.
1. Locate the ½”-13 X 2.5” socket head
bolts from the kit. Before installing, apply
two or three drops of blue threadlock to
the threads of the new shock bolts. (FIGURE 5)
2. Install the new air shocks one at a time.
Start the lower bolts first. Then adjust the
height of the bike to line up the upper bolt
holes. (FIGURE 6)
3. Use a 3/8” Allen head driver and torque
wrench to tighten the upper and lower
shock bolts. (FIGURE 7)
4. Install the bolt covers onto the shock
absorber bolts. Lubricate the o-ring inside
with an appropriate lube. Gently press the
cover on with a slight twisting motion until
you feel the caps drawn solidly onto the bolt
head and firmly seated. (FIGURE 8)
5. Installation complete.
AIR SHOCKS INSTALLATION
Tighten all nuts and bolts to manufacturer's specifications during the installation process.
The inflation system consists of a compressor with a separate distribution manifold along with an inflation switch
and compressor relay. Pump locations may be affected by emissions control components. If equipped, an alternate
pump location will need to be found.
1. Remove the seat. (FIGURE 9)
2. Remove both side cover panels. (FIGURE 10)
3. The Electronic Control Module is located
directly under the seat. Remove the clip
and lift the ECM out of the way (you will
not need to disconnect it), to access the
battery. (FIGURE 11)
4. Loosen and remove the torx bolt
retaining the battery cover. Remove the
plastic cover after removing the torx bolt. (FIGURE 12)
5. If the motorcycle is a model year 2009-
2013 skip to step #9.
Remove the two bolts attaching the lower
saddle bag support on the right side of the
motorcycle. (FIGURE 13)
6. Locate the supplied hex bolt and nyloc
nut. You will also need the longer factory
saddle bag support bolt and nut that was
removed from the right side of the bike
during step #5. (FIGURE 14)
The Arnott accessory kit K-2850 is necessary when installing Arnott Ultimate Ride Kits MC-2904, MC-2905, MC-2906 and MC-2907 or Smooth Ride Kit 9048 kit for 2014-Present Harley-Davidson® Touring motorcycles equipped with Harley-Davidson’s Saddle Bag Guard Rails (P/N 90200561) or 2014-present CVOTM Touring motorcycles with O.E. speakers in the saddle bags. This kit includes CNC Machined aluminum spacers and additional hardware that was designed to securely adjust the placement of the air suspension compressor so that it will not interfere with the Bag Rails or touch the CVO Speaker connection harness. To order this kit call 1-877-900-0247 or visit www.arnottcycles.com
7. Insert the supplied hex bolt through the support as shown below. (FIGURES 15, 16)
8. Slide the air pump and bracket assembly
onto the hex bolt. Then thread on the nyloc
nut. Insert the longer factory bolt through
the other hole/slot in the bracket. Tighten
both bolts and confirm that the pump is at
least 1/2” from touching the brake rotor. If
the pump is too close to the rotor you may
need to place a washer over the hex bolt,
between the pump bracket and the frame.
Then retightnen the nuts and bolts. (FIGURE 17)
9. If the mototcycle model year is 2014 to
present, skip to step #11. If the motorcycle
is a model year 2009-2013 you will need
to install then tighten the supplied hex
bolt and non-nyloc nut onto the air pump
bracket as shown below. (FIGURE 18)
10. Remove the factory bag support bolt on the right side of the motorcycle and install the pump
bracket bolt through the hole. Tighten the supplied nyloc hex nut on the back side. (FIGURES 19, 20)
11. Insert the 1/4” air hose into the push-to-connect fitting on air pump. Then plug the included red
wire extension into the red pump wire. Using the supplied zip ties and split loom, route/attach the
air hose and pump wires up along the frame toward the right side battery cover. Be sure that the
wheel will not rub the hose or wires when the motorcycle is in motion. (FIGURES 21, 22)
12. Find a suitable location for the
distribution manifold. Locate the larger
1/4” tubing, connect the manifold to the
compressor via the 1/4” push to connect
fittings. (FIGURE 23)
13. Next, attach the 4mm air line fittings
to the 4mm tubing provided in the kit and
insert into the two ports on the manifold as
depicted. (FIGURE 24)
Inserting the hose too far through
the fitting may result in blockage of air flow.
14. Route the airlines, from the previously
installed manifold, to the rear air shocks.
Install two more fittings on the hose and
insert into the rear air shocks. (FIGURE 25)
Air line fittings seal with O-rings, do not
overtighten!
15. Locate a suitable mounting location
for your toggle switch. Mount in a location
that will provide ease of access. Such as
behind the rear cylinder on the left side
cover. (FIGURE 26)
If installing the upgraded handlebar
mounted control switch, follow the wiring
instructions included with upgraded switch.
16. Included in the kit is a system relay,
refer to the schematic for a wiring diagram. (FIGURE 27)
At this time reinstall the battery.
17. A preferred location for the universal
fused wiring harness is under the seat,
near the battery. Connect the red wire,
(with the ring terminal), to battery positive.
Reconnect the battery cables, torque the
terminals. (FIGURE 28)
A system schematic is included for reference.
18. Replace the plastic battery cover and
electronic control module. (FIGURE 29)
19. Replace the side panels. (FIGURE 30)
20. Replace the seat and saddlebags. (FIGURE 31)
21. Installation complete.
Never make adjustments to the air suspension system while the motorcycle is in motion. Adjusting the air suspension
while vehicle is in motion can affect the stability and handling, which could result in death or serious injury.
