Product Description When you install an aftermarket long-arm suspension on a Jeep Gladiator JT, the rear lower control arm brackets are often relocated along the frame rails. That creates a clearance problem when installing traditional frame-mounted rock sliders because the rear rocker guard mounting brackets can occupy the same space as the suspension brackets. The Motobilt MB1259 Frame Mounted Rocker Guards are designed specifically for Gladiator builds where rear long-arm suspension mounting locations require additional fabrication clearance. Unlike body-mounted rocker guards that transfer impacts into the sheet metal and body mounts, the MB1259 rock sliders weld directly to the Jeep frame. This creates a barrier between the Gladiator body and trail obstacles while directing impacts into the frame instead of the body panels. The MB1259 kit includes a pair of fully welded rocker guard assemblies with the rearmost frame mounting connections left off. Loose mounting tubes, plates, and gussets are included so the installer can position and fabricate the rear frame connections around the existing long-arm suspension brackets. This allows the mounting layout to be adapted to many aftermarket rear long-arm suspension configurations without having to redesign the entire rocker guard. The main slider sections are constructed from 2" DOM steel tubing. The frame mounting plates, end caps, center bracing, and gussets are fabricated from 3/16" steel plate, with laser-cut and CNC-formed components used throughout the assemblies. These Gladiator rock sliders are built for fabricators who need frame-mounted rocker protection without ignoring the suspension packaging underneath the Jeep. The kit ships in bare steel and requires fitting, welding, and protective finishing. Step-by-step installation instructions are included to guide the fabrication and installation process.
