JK Cargo Roof Rack Mount: Key Fit Facts

Learn the essential fit facts for installing a cargo roof rack mount on your 2007-2018 Jeep Wrangler JK 2-door or 4-door, including accessory mounting and step pad use.

Quick answer

For a 2007-2018 Jeep Wrangler JK, the Body Armor 4x4 Cargo Roof Rack Accessory Mount fits both 2-door and 4-door models on the driver or passenger side, with a built-in step pad rated for 250 lb for roof access.

Why the JK cargo roof rack mount is different

Unlike universal roof racks, the Body Armor 4x4 mount is designed specifically for the JK's factory roof rails and hardtop contours. This means no drilling or modifications are needed, and the mount sits flush against the roof line for a clean look.

The mount plate includes an integrated step pad that supports up to 250 lb, making it easier to reach gear on the roof without standing on the door sill or seat. This is a practical advantage for daily loading and unloading.

Compatibility and limitations

The mount works on both 2-door and 4-door JK models from 2007 to 2018. It is sold in pairs, with one plate per side. You can install it on the driver side, passenger side, or both for symmetrical accessory mounting.

One limitation: the mount is designed for the JK hardtop only. If you have a soft top or aftermarket roof rack system, this accessory mount may not fit without modifications. Always verify your roof type before ordering.

Step-by-step installation guide

  1. 1. Gather tools and inspect the mount: You will need a socket wrench, the included mounting hardware, and the two accessory mount plates. Inspect each plate for the step pad and powder coat finish. Check that all bolts and brackets are present. Common mistake: assuming the mount comes with a single plate. It is sold as a pair, so you get one for each side.
  2. 2. Position the mount on the JK hardtop rail: Place the mount plate on the driver or passenger side roof rail, aligning the pre-drilled holes with the rail slots. The step pad should face outward for easy roof access. Do not tighten yet. Checkpoint: ensure the mount does not interfere with the door seal or soft top track. If it rubs, adjust the position slightly.
  3. 3. Secure the mount with provided hardware: Insert the bolts through the plate and into the rail slots. Hand-tighten them, then use a socket wrench to torque to the manufacturer's specification (typically 15-20 ft-lb). Do not overtighten, as the aluminum rail can strip. Common mistake: overtightening the bolts can damage the roof rail threads. Use a torque wrench if available.
  4. 4. Attach accessories to the mount plate: Use the quick fist mounts or molle bag straps to secure your Rotopax, Hi-Lift jack, or other gear to the plate. Ensure the load is evenly distributed and does not exceed the 250 lb step pad limit. Checkpoint: test the step pad by applying light pressure before fully loading the roof. If it feels loose, recheck the mount bolts.
  5. 5. Repeat for the opposite side (optional): If you purchased a pair, install the second mount plate on the other side using the same steps. This gives you symmetrical accessory mounting and balanced roof access. Common mistake: installing only one side when you need two for heavy or wide gear. For large items like a roof basket, both mounts provide better stability.
