GENERAL NOTES:
These instructions are also available on our website; www.synergymfg.com.
Check the website before you begin for any updated instructions and additional
photos for your reference.
This is a weld in roll cage kit, all welding should be performed by an experienced
welder with proper welding equipment
Use in conjunction with PPM-5203; TJ/LJ front cage kit
This kit works with either a soft top or hard top
Use extreme care when welding and grinding in the interior of your Jeep, remove
or cover any components you do not want welding spatter or grinding sparks to
damage.
Note, if you want to retain the factory roll bar padding you will have to cut holes
where the tubes attach, position the tubes through the padding, slide the padding
over the tubes and weld. Thus, if roll bar padding is retained, plan ahead and
notch the padding as tubes are installed.
1. Remove the hard top or soft top, if using a soft top, remove the door surrounds.
2. Remove the sound bar, front and rear upper seat belt mounts, rear roll bar padding and
B-pillar padding and trim.
3. Install the PPM-5203 front cage kit per the instructions included with the front cage
kit
4. Remove the paint on the factory cage around the areas to be welded. Position the C-
pillar cross bar and the B to C pillar spreaders as shown below (Picture 4.1)
Picture 4.1 Complete rear kit tacked into place for reference.
(Note: C-pillar cross tube sits in with bends slightly kicked up from horizontal to the
ground. B to C-pillar spreaders positioned with bends towards rear of vehicle.)
5. The distance between the C-pillar cross bar and the factory B-pillar should be 19”
Picture 5.1
6. The distance between the B to C-pillar spreaders on the C-pillar cross tube should be
31” to the inside of the tubes. The tubes should land approximately at the start of the
bend.
7. The distance between the B to C-pillar spreaders on the factory B-pillar should be 7”
8. Position the C-pillar cross bar gussets as shown below. The lower part of the gusset
goes right inside of the upper seat belt mount with the bottom of the gusset lining up
with the top of the seat belt bung as shown in picture 8.1. The upper part of the
gusset goes right under the upper B to C-pillar spreaders and should line up with the
outer edge as shown in picture 8.2.

9. Double check all measurements before tacking. Fit hard or soft top to ensure proper
clearance. Once satisfied, securely tack all tubes into position. Tack each tube in at
least 3 spots to help prevent distortion during final welding.
10. You can finish weld all of the tubes now. Remember, if you want to retain the
factory roll bar padding you will have to cut holes where the tubes attach, position the
tubes through the padding, slide the padding over the tubes and then weld for the
cleanest installation possible.
11. Clean the welds and paint the new tubes.
12. Installation is complete.
