Rear Seat Upper Tube Kit Add-On for Jeep JK 2 Door Roll Cage System

Once a Jeep JK 2 door starts getting built for real trail use, interior space becomes a tradeoff. Most full cage systems prioritize strength and clearance, which leads to a fastback-style rear section that limits usable space for rear passengers.

The Motobilt rear seat tube kit was designed to solve that problem without redesigning the entire cage system. This kit is an add-on to the Motobilt JK 2 door roll cage system and modifies the rear upper structure to maintain headroom for passengers.

Instead of running the fastback rear profile, these additional tubes change the layout of the rear section to a more vertical structure. This allows builders to retain a usable rear seat while still keeping the strength, triangulation, and overall layout of the main cage.

This is not a standalone roll cage. It is a conversion kit that works with the existing Motobilt JK 2 door cage system. The base cage must already be installed or purchased separately.

The tube placement follows the same design approach as the rest of the cage system, keeping the structure tight to the body while maintaining visibility and usable interior space. It allows builders to choose between a tighter fastback profile or a more functional rear passenger layout depending on how the Jeep is used.

Like all Motobilt products, this kit was designed by builders who understand Jeep JK packaging, fabrication, and real trail use.
