Jeep JKU Roll Cage Kit & Parts FAQ
What tubing does the MB3033 JKU cage use?
The kit specifies 1.75-inch DOM tubing with a 0.120-inch wall. Tubes are bent, notched and labeled for fit-up, with mounting plates and hardware listed on the product page.
Are the harness and rear X-bar tubes included?
Yes. The product lists the B-pillar harness, C-pillar harness and rear X tubes as included pieces. Have a qualified professional welder/fabricator follow the exact kit instructions for the intended configuration. Do not treat included configuration options as permission to alter cage tubing or omit structural tubes outside those instructions.
Can I keep my factory seats and top?
The MB3033 product describes physical fitment for specified factory seats, belts and hardtop, plus separate requirements for supported soft tops and accessory brackets. Review the exact setup with a qualified professional welder/fabricator. Physical fitment does not guarantee that factory safety systems remain functional; cage installation may interfere with or disable airbags and crash sensors.
What is the difference between MB3033 and MB3032?
MB3033 is the JKU cage kit with its specified tubing. MB3032 is a bracket-only kit for a custom JKU four-door cage; tubing is not included.
Does the JKU cage require a professional installer?
Yes. A qualified professional welder/fabricator must remove the factory cage, fit and weld the new cage, then finish and reassemble the vehicle. Factory-panel modification may be necessary. Improper installation can result in serious injury or death.
Can Motobilt roll cages be used for racing, motorsports or highway driving?
No. Motobilt roll cages are exclusively for off-road recreational use. They are not designed, tested or rated for racing or motorsports and must not be used for competitive or high-speed activities. They are not certified or intended for on-road or highway use. Installation may render the vehicle non-compliant with federal, state or local requirements.
Does a roll cage guarantee occupant safety or preserve the factory safety systems?
No. A cage improves structural rigidity but does not guarantee occupant safety or survival in every rollover or impact. Cage installation may interfere with or disable airbags and crash sensors. The user assumes responsibility for these effects and the risks of using the vehicle.
What are the installation requirements and risks?
A qualified professional welder/fabricator is required. Improper installation can result in serious injury or death. Modification of factory panels may be necessary. Review the exact product instructions and its Important Safety & Liability Notice before installation.
Can I drill, notch or cut cage tubing for wiring or accessories?
No. Do not drill, notch or cut cage tubing to route wiring or mount accessories; this compromises its strength. If an opening is necessary, the product notice requires reinforcement with a welded-in bung or for the hole to be fully welded closed. Have a qualified professional welder/fabricator address this requirement; do not treat it as permission to leave an unreinforced opening.
What warranty and liability terms apply to Motobilt roll cages?
Motobilt roll cages are sold as-is, without express or implied warranties, including merchantability or fitness for a particular purpose. Motobilt assumes no liability for injury, death or property damage. The end user assumes the risks. Read the full Important Safety & Liability Notice on the cage product page before purchase or use.
