🔥 Custom Jeep Cargo Rack 🔥

🛠️ Another custom fabrication project completed at Rimrock Manufacturing.

This rack was designed and built in-house for a Jeep owner looking for additional cargo space without compromising the vehicle's functionality or appearance.

💪 Constructed from steel tubing and expanded metal, the rack mounts securely to the roll cage using a custom clamping system designed specifically for this application.

🔧 To achieve the precise fit this project required, our team also utilized custom 3D-printed components during the design and mounting process—showcasing how modern technology and traditional fabrication can work together to create a truly custom solution.

🏕️ Whether it's camping gear, hunting equipment, recovery gear, or tools, this rack is built to handle the job.

🇺🇸 Proudly designed and fabricated in Colusa, California.
