Description
Aftermarket long-arm rear suspensions on the Jeep Gladiator JT often relocate the rear lower control arm mounting brackets on the frame, which can interfere with traditional weld-on frame-mounted rocker guards. The Motobilt MB1259 Frame Mounted Rocker Guards for Long Arm Suspensions are specifically engineered to solve this issue while delivering the same extreme protection Motobilt is known for.
Built to withstand serious trail abuse, these rocker guards are welded directly to the frame, creating a true structural barrier between your Gladiator’s body and trail obstacles. Unlike body-mounted sliders, impacts are transferred directly into the frame rather than the body or body mounts—dramatically reducing the risk of sheet metal damage on extreme terrain. They’re also strong enough to be used as a jack point, giving you confidence during trail repairs or recoveries.
The frame mounts are constructed from 3/16-inch thick laser-cut steel plate, CNC-formed into boxed structures that spread loads efficiently across the frame while accommodating long-arm suspension geometry. This boxed design provides significantly more surface area and strength than traditional tube-and-gusset mounts, ensuring durability even under hard impacts.
The slider portion is built from 2-inch DOM steel tubing, with end caps and center bracing fabricated from the same 3/16-inch formed steel as the mounts. Each set ships fully welded in bare steel, ready for final positioning, welding, and finishing.
If your Gladiator is equipped with a long-arm suspension and sees demanding trails, these frame-mounted rockers are essential protection for both your body and chassis.
