Jeep JKU Cargo Compressor and Auxiliary Battery Mount

Utilizing all of the space in a JKU is a tough task. Most often, the space in the little cubby hole below the cargo floor in the rear of a JK is underutilized. That’s no longer a problem when you incorporate our Jeep JKU Cargo Compressor and Auxiliary Battery Mount. We also give you the option to incorporate an additional auxiliary battery to keep all of your accessories powered during your adventures.

Made from 5052 1/8″ aluminum, this bracket is built to handle the stress of these heavy components.

Installation

NOTE: If retaining the OEM plastic on the sides, as most everyone does, this bracket will reside below the plastic, against the floor of the body.

1. Remove the OEM cargo cover (the flappy thing covering the cubby) if you still have it.
2. Temporarily install the bracket into the cubby hole and attach with the OEM bolts
3. Mark the center hole to be drilled. The hole you need to transfer to the body is identified in this photo. Mark the hole from above.
4. Remove the bracket and drill the marked hole using a 3/8″ drill bit
5. Install the rivet nut into the hole (can use our Basic Rivet Nut Kit if needed)
6. Place the included spacer on top of the rivet nut, carefully so it stays aligned.
7. Carefully place the bracket back into the Jeep, paying attention not to disturb the location of the spacer below.
8. Before installing the side bolts, insert the M6x50mm bolt through the bracket into the rivet nut. Do not tighten – keep loose.
9. Install the side OEM bolts.

NOTE: This requires removal of the plastic that surround the cubby area below the cargo area. There just isn’t enough vertical room for these components when this plastic is retained. The plastic part just sits in the cubby, so removal is quick and easy.

Hardware included with the main bracket:

• (1) M6x50mm Button Head Bolt
• (1) 3/4″ Plastic Spacer
• (1) 6mm Rivet Nut

Battery Options

Due to the apparent long-lasting effects of people eating bats, we are having continuous supply chain issues with keeping batteries in stock. So, going forward, we are just going to link out to third parties for batteries. Below are the batteries for which we build hold-down brackets. We have also had some issues with the battery manufacturers changing the dimensions of the batteries. Please pay attention to the dimensions listed below for each battery. The brackets are built with tight tolerances and will not fit batteries of varying sizes.
