How to Install Kargo Master Mod-Rak EXP System (07-17 Wrangler JK 4 Door) on your Jeep Wrangler

Step 1
 Bolt end panel to end tube using three 5/16" x 2" button head cap screws, six 5/16" flat washers and three 5/16" NYLOC nuts.
 Insert end caps into both ends of bent tube.
 Set assembly to the side

Step 2
 Slide three 5/16" carriage bolts on opposite sides of each other on the 52.5" extrusion.
 Do not slide carriage bolts in the side with the counter bore on face.
 Repeat for a total of 2 of these extrusion with bolt assemblies.
 On the remaining extrusion, place carriage bolts only on one side.

Step 3
 Use extrusion (2) and bolt end panel assembly using three 5/16" flat washers and three 5/16" NYLOC nuts .
 The counter bore on the extrusion faced towards the bottom of the platform.
**Set assembly to the side**

Step 4
 Bolt mid panels (55075-00-001) together using three 5/16" carriage bolts, three 5/16" flat washers and three 5/16" NYLOC nuts.
 Repeat and make two of these assemblies and set to the side.

Step 5
 Bolt mid panel assemble to the other side of 52.5" extrusion built in step 3 using three 5/16" flat washers and three 5/16" NYLOC nuts.

Step 6
 Bolt another 52.5" extrusion (2) with carriage bolts to the other side of the mid panel assembly using three 5/16" flat washers and three 5/16" NYLOC nuts.

Step 7
 Bolt the remaining mid panel assembly to the other side of the previously installed 52.5" extrusion using three 5/16" flat washers and three 5/16" NYLOC nuts.

Step 8
 Bolt the remaining 52.5" extrusion (1) to the open end of the mid panel assembly using three 5/16" carriage bolts, three 5/16" flat washers and three 5/16" NYLOC nuts.
 Be sure to have the counter bore hole facing away from the perforations on the panels.

Step 9
 Bolt eight 5/16" carriage bolts into each side of the 4 panels. Be sure to have the
washers and NYLOC nuts on the underside of the panels with the head of the carriage
bolt facing outwards.

Step 10
 Slide 65" extrusion up the length of the panels, picking up each of the 8 carriage bolts installed in previous step.

Step 11
 Place platform assembly so it is resting on the perforated panels.
 On each 65" extrusion, slide five 5/16" x 3/4" carriage bolts into the extruded slot that is facing upwards.
 Slide one end feed fastener in the extruded slot on the outside of each 65" extrusion.
 On each 52.5" extrusion, two 5/16" x 3/4" carriage bolts to each side of the hole in the center. (see picture for approximate carriage bolt locations)

Step 12
 In the front of the platform, place Front Support BRK (55075-11) to connect the front hoop(55075-00-003), 65"extrusion (55075-00-005) and 52.5" extrusion (55075-00-004). This bracket will pick up previously placed carriage bolts in the extrusions.

 Bolt through 55075-11 and 55075-00-003 into 55075-004 using a 5/16"-18 x 2-1/4" button head, one 5/16" lock washer and one 5/16" flat washer.

 Bolt through 55075-11 and 55075-00-003 using a 5/16"-18 x 2-1/4"  button head, two 5/16" flat washers and one 5/16" NYLOC nut. Do this  in both holes as shown in picture.  

 Slide end feed fastener down to the remaining hole in the support bracket. Bolt 55075-11 to the 65" extrusion using 5/16"-18 x 3/4" Button head, one 5/16" lock washer and one 5/16" flat washer. Bolt into the end feed fastener. (see picture)  

**REPEAT ON BOTH SIDES

Step 13
 In the middle of the platform install mid support (55075-12) using three 5/16" carriage bolts, three 5/16" flat washers and three 5/16" NYLOC nuts.
 Repeat on both sides

Step 14
 In both rear corners bolt corner support (55075-13) to extrusions using three 5/16" carriage bolts, three 5/16" flat washers and three 5/16" NYLOC nuts.

Step 15
 Bolt end caps to open end of extrusions using a 5/16" x 3/4" Button Head Cap Screw

Step 16
 Align and square all peices on platform. TIGHTEN all bolts at this point.

Step 17
 On the underside of the platform, slide two 5/16"-18 x 1" carriage bolts to each side of access hole on all three 52.5" extrusion.
 Place platform on top of JEEP roof rails. Center on JEEP and determine how far front to back you would like the platform.

Step 18
 Apply bumper to front tube where it sits along the roof rails.

Step 19
 Depending on the width of the roof rails installed on JEEP will determine the orientation of the mounting brackets.
 If the roof rails are less than 36" apart, the mounting of the platform will be more convenient.
 Bolt mounting bracket (60310-00-001) to roof rail using the carriage bolts installed in step 17 and two 5/16"-18 flanged NYLOC nuts.
 Repeat on each 52.5" extrusion.
*snug tighten until all 6 brackets are installed*

**If your roof rails are farther apart than 36", the mounting brackets must be flipped and bolted on the inside of the roof rails.

Step 20
 Align and center platform to your liking. Tighten all 12 NYLOC nuts to secure mounting brackets and platform to roof rails.

YOUR INSTALLATION IS NOW COMPLETE
