The EXR3811 Camper Roof Rack Crossbar Package is a No-Drilling roof top tent–ready, heavy-duty crossbar rack system designed specifically for Jeep Wrangler JL and JLU and Jeep Gladiator JT vehicles equipped with a factory hard top (2018–present). Built around three full-length EXR crossbars, the EXR3811 creates a rigid, modular foundation for carrying rooftop tents, overland gear, outdoor equipment, and work-grade cargo in demanding real-world conditions.
Designed for users who need more than a basic crossbar setup, the EXR3811 provides increased rigidity, balanced load distribution, and long-term durability—without drilling or permanent vehicle modification. Whether you’re transporting a rooftop tent, kayaks, cargo boxes, recovery gear, or expedition equipment, this system delivers a dependable roof-mounted solution for both daily use and extended travel.
Purpose-Built for Rooftop Tents & Heavy Loads
The EXR3811 is engineered specifically for applications where stability and load management matter. Its three-crossbar layout improves overall system rigidity while distributing loads more evenly across the vehicle roof, reducing stress concentrations compared to traditional two-bar systems.
At the core of the system is EXR’s patented weight distribution design, developed through years of real-world use and testing. This design helps manage both static and dynamic loads more effectively, making the EXR3811 well suited for rooftop tent installations, overland travel, and long-term vehicle mounting.
Accessory-Ready Compatibility
All EXR3811 variants use standard-size crossbars compatible with the majority of aftermarket roof-mounted accessories, including kayak carriers, cargo baskets, roof boxes, bike mounts, recovery accessories, and utility gear from leading manufacturers.
Select variants also feature EXR’s click-in crossbar profile, designed to integrate with EXR click-in accessories while retaining full compatibility with traditional clamp-style mounts. This dual-compatibility approach ensures flexibility today and expandability as your gear setup evolves.
Construction & Materials
EXR crossbars are built for continuous outdoor exposure and demanding use. Each bar is constructed from heavy-duty materials and finished for corrosion resistance, making the system suitable for year-round driving, wet environments, and extended vehicle installation.
This platform has proven itself in both recreational and overland applications as well as commercial and fleet use, where racks are subjected to frequent loading, vibration, and long service life. All mounting hardware is selected to withstand real-world conditions—not just ideal test environments.
