What the Kit Includes:


1) Installation Instructions
2) "Shotgun" Shock Body Unit
3) Chrome Compressor
4) Evolution Style Mounting Bracket or twincam style mounting bracket
5) Switch Harness with 2 switches and wire housing connector
6) Relay Harness

Installation Overview.

1) Check contents of package to ensure you have unit for correct year, correct compressor and bracket and two part wiring harness and harness components.
2) Secure motorcycle so you could remove stock shocks easily.
3) Route relay harness through hole in rear right corner of battery box.
4) Remove stock shocks.
5) Install compressor and bracket and route compressor wiring up through same hole as relay harness.
6) Install shotgun shock body and connect relay harness to electrics from body. Make sure section of melt wall is used.
7) Secure shock body to frame and swing arm with HD style shoulder bolts and nuts. Use lock tight and torque to OEM specs.
8) Do not shim gap on shoulder bolt as shafts could bind.
9) Mount switches and route harness, preferably on left side of dash. Cover harness with shrink tubing and attach housing according to color code.
10) Plug switch harness to short lead of relay harness use melt wall to secure. Relay harness has three wires. Black goes to any ground, red goes to 12 volt positive, and spade connector attaches to red from compressor and black from compressor goes to ground. Check fuse holder for 20 amp fuse.
11) Now you can operate switches.

Relay harness Install


1) There are two harness', one is the Relay harness with shrink wrapped electronic components. The other is the switch harness with switches located on one end of the harness. (switch harness comes different for 2000 and up. and 99 and below.)
2) Route long lead of relay harness befor installing shotgun shock body.
3) Route long lead of realy harness through hole in rear right corner of battery box. And let harness hang long to be plugged into shotgun shock body.
4) As you install shotgunshock body, plug pigtail into the relay harness with piece of melt wall on harness and continue to bolt in body.
5) After checking electrical system and shotgunshock to work, heat melt wall onto the housing.
6) There are three wires, black is ground, red is hot, and spade connector goes to hot on compressor.(be sure to connect possitive after routing wires)

Compressor Install


2000 up install: With Charcoal Cansiter:

1) Remove charcoal canister BRACKET by cutting it in half and unscrewing the two halfs
2) install compressor and bracket from bottom with the head pointing down and toward primary side of bike(side with airline fitting) The compressor can be rotated by losening the pinch bolts.
3) Use special shoulder bolts (provided) and screw in 5/16-18 bolts, access head of sholder bolt from right side of bike with a thin 1/2inch wrench. (be sure to use locktight on shoulder bolts. And torque to 25ft lbs.
4) Rotate head of shoulder bolts to clear debrees deflector. Then tighten pinch bolts seccurely. (be sure to not over tighten, could possibly damage compressor)
5) Now route compressor wireing up through right rear hole in oil tank. As they will plug into the battery compartment.
6) plug in 1/4 dot air line provided and route towards right side of bike

Bikes without Charcoal canister.:

1) There are two holes at the bottom of the transmission, and you will tap them 7/16 14,no drilling is necessary.
2) Mount the compressor with the bracket installed, the head pointing toward the left of the bike and rotated down, the compressor can be rotated by losening the pinch bolts. Use 7/16 14 socket head screws provide and tighten to 25 ft lbs and use locktite.
3) Rotate head of shoulder bolts to clear debrees deflector. Then tighten pinch bolts seccurely. (Be sure to not over tighten, could possibly damage compressor)
4) Now route compressor wireing up through right rear hole in oil tank. As they will plug into the battery compartment.
5) Plug in 1/4 dot air line provided and route towards right side of bike.

99 and down compressor install

1) Figure 8 bracket is used to clamp onto the access tube and compressor
2) Mount compressor with head toward left (primary side) facing up infront of access tube.
3) Socket head screw on figure 8 bracket will face toward rear of bike and will mount on access tube and compressor at same time.
4) Now route compressor wireing up through right rear hole in oil tank. As they will plug into the battery compartment.
5) Plug in 1/4 dot air line provided and route towards right side of bike.

Custom Bike compressor install

1) Figure 8 bracket is designed over 1inch access tube.
2) Some custom bikes have larger diameter access tubes. If this is the case, contact shotgunshock for custom bracket.


To install unit on a 99 and down stock HD and all custom bikes with an evo style drive-train use the shotgun body shown.


1) the shotgun logo will face up and the spherical ends will connect to the swingarm while the other eyelets without sperical bearings connect to the frame. The eyelet ends are always shipped with locktite on them unless the unit is to be customized and the eyelets need to be removed for alteration. Always use loctite for final installation of eyelets.
2) use four stock sholder bolts , they are 5/8 shoulder diameter. Make sure that the bolts line up straight into the frame thread. Sometimes it is necessary to clean the frame thread with a tap. The bolts will dead end on the frame and there will be a gap between the head of the bolt and the shock. This is correct and you should not put shims in this gap. On some custom frame the bolt maybe to short and will start to bind on the shock before the shoulder dead ends on the frame. In this situation a longer shoulder bolt must be used. The bolts should never be in a position to bind the shock, as this could cause severe damage to the shock. Loctite should always be used on shoulder bolt threads at final install. Some anti seize can be placed on the shoulder. If the shoulder goes into the eyelet hole to tight ,the shoulder can be lightly sanded for adequate clearance. Torque bolts to OEM specs


This Shotgunshock body will be used on 2000 and up stock HD with twin cam style drive trains. The instructions are the same as for the evo style installation. Logo faces up and use stock HD hardware with locktite and torque to OEM SPECS

Switch Harness install


1) On stock bikes we prefer to mount switched on left side of dash, for easy accessability.
2) Unbolt dash and look inside for proper possition to drill holes for switch mounts.
3) Drill two 1/4 inch holes 7/8's of an inch apart.
4) install switches from inside through holes and screw the rubber boot on outside to secure the shotgunshock switches.
5) install heat shrink over switch harness and melt.
6) on 99 and down switches rout under dash toward battery compartment. v7) On 2000 and up switch harness tape end of wiring together to protect locking tangs on end of exposed wires, rout toward front of bike underneath gas tank, toward battery compartment.
8) install connector housing according to color code on relay harness, with supplyed melt wall over housing connector.

Custom Installation of switch harness

1) If not mounting on dash of motorcycle. fabricate custom bracket or find mounting location. 2) Route wires accordingly to switch mounting location, then cut wires to length and re-solder cut wires. 3) follow switch harness instructions.

Switch operation

Make sure motorcycle is in a secure position and will not tip over when height position is changed. Front wheel should tilt to left.
1) Switches have three positions a)middle is off b) up should be stationary, stays in place until manually moved c) down should be momentary, moves back to neutral when not held
2) Put both switches up, they should stay up in the stationary position. This will raise the suspension as fast as possible since the compressor will fill the air cavity to raise the bike and the other switch will open the cavity that pushes the bike down. Allow the bike to rise to full height and then after ten seconds put switches in neutral position.
3) Now that the bike is all the way up, it is in the position to adjust for both height and firmness. To lower the bike you will move the switch that turns the compressor on when the switch is in the down, momentary position. If the switches were mounted in the dash, this switch will be toward the front of the bike. s
4) After you set the bike in any position you prefer to ride in at this time, you can check for firmness by vigorously pushing down on the rear fender. If you want to firm up the suspension this can be done without changing the ride height. To achieve a firmer ride move the switch up into the stationary position, the switch that turns on the compressor. If the switches are on the dash, the one for firming will be toward the rear of the bike. s
