SYNERGY MFG. 870 INDUSTRIAL WAY, SAN LUIS OBISPO, CA (805) 242-0397
PPM-5014-A JK REAR AIR-BUMP KIT
Version 1.1
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.
The instruction pictures below were taken on a 4dr Jeep JK.
The installation of this kit requires cutting of the factory frame. A cut off wheel, plasma cutter or oxy-
acetylene torch will be needed to complete installation. The air-bump mount will need to be welded to
the factory frame rail. An experienced fabricator/welder is recommended to properly install this kit.
This kit is designed to set the rear suspension at a 3” bump stop spacing.
INSTALLATION:
1. Strip the rear suspension down to the point where it can be cycled fully from bump to droop and articulated
from side to side, removal of coils and shocks should suffice for proper cycling of rear suspension.
2. Cut the factory bump stop mount off the frame. A 4 ½” cut off wheel and grinder works well for this.
a) Cut along the weld and try not to cut into the frame.

3. Clean up the remainder of the area with a grinder / sanding disc until the frame is smooth.
4. With the frame cleaned up, measure 6-1/2” and 9-1/2” back from the frame hole shown below.
5. Mark cut lines on both top and bottom of frame. Cut lines should go to the back of the first weld seam on
both top and bottom of frame. See images below.

6. Next, cut out the outlined section of frame. Clean up any rough edges and remove paint from frame for
welding. Completed cut should appear as shown below.
