JLU
Once you move past basic lift kits on a Jeep JLU, the factory suspension layout becomes the limiting factor. The stock control arm geometry, frame mounting points, and underbody layout were never designed for long travel suspension, coilovers, or 1 ton axle swaps. Builders trying to piece together a custom 4 link setup often spend a lot of time fighting link placement, clearance issues, and poor geometry.
The Motobilt 4 link suspension bracket and skid system for Jeep JLU is designed to remove that guesswork and give you a solid foundation to build a real suspension system. This kit provides all the frame side bracketry needed to build a true double triangulated rear 4 link and either a 3 link or 4 link front suspension depending on your steering setup. That flexibility allows you to run mechanical steering with a track bar or step up to full hydro with a triangulated front.
The system replaces the factory crossmember with a heavy duty removable transmission crossmember that also serves as the front lower link mount location. A 1/4 inch thick skid plate ties into that structure and follows the contour of the drivetrain for a smooth belly. In the rear, a new crossmember integrates directly with the frame and supports the rear link brackets while also acting as part of the skid mounting structure.
This setup also addresses underbody protection. The included engine skid spans forward of the oil pan and ties into the crossmember to protect the oil pan, transmission, and exhaust routing. The flat belly design improves clearance and eliminates hang-up points on obstacles.
Like other Motobilt systems, this kit was built from real fabrication experience. Every bracket, mounting point, and service access detail reflects time spent building and repairing Jeeps that see real trail use. This is not just a bracket kit. It is a foundation for a properly built Jeep JLU suspension system.

A 4 link suspension replaces the factory control arm layout with a suspension system that gives the builder more control over axle movement, suspension geometry, and drivetrain clearance. On a Jeep JLU, this becomes important once you move into coilovers, ORI struts, long travel suspension, or 1 ton axle swaps.
A properly designed 4 link setup improves articulation, suspension travel, and overall axle control while allowing the suspension to cycle more smoothly through rough terrain.
A double triangulated 4 link uses angled upper and lower links to control side-to-side axle movement without relying on a track bar. This creates cleaner suspension packaging and improves articulation during rock crawling.
Builders often choose this setup because it provides more consistent axle control through suspension travel while eliminating the side loading created by a traditional track bar system.
The factory Jeep JLU fuel tank occupies the same area needed for rear suspension links and suspension travel. Once you start building a true triangulated 4 link, the factory tank location becomes a major packaging limitation.
Relocating the fuel tank creates the space needed for proper rear link geometry, driveline clearance, and suspension movement.
Yes. This system was designed around the needs of serious suspension builds using coilovers or ORI struts. The bracket placement, skid structure, and chassis layout help create the clearance required for larger shock packages and increased suspension travel.
This makes the system a solid foundation for high travel Jeep JLU builds.
Yes. The skid and crossmember design provide clearance for larger aftermarket transfer cases including Atlas II and Atlas IV setups commonly used in advanced rock crawling builds.
The flat belly layout also helps improve underbody clearance and reduces hang-up points on obstacles.
Yes. This system supports either a front 3 link with track bar or a triangulated front 4 link depending on your steering setup.
Builders using mechanical steering commonly run a front 3 link with track bar. Full hydro steering setups can be configured with a triangulated front 4 link.
Yes. This is a fabrication-focused suspension system designed for serious Jeep JLU builds. All primary brackets weld directly to the factory frame.
Professional welding, accurate suspension setup, and proper geometry planning are strongly recommended during installation.
Yes. The integrated skid and crossmember system creates a much smoother underbody profile compared to the factory layout. The skid follows the contour of the drivetrain to help reduce hang-up points while improving clearance under the Jeep.
