Aluminum 15" Stretch Over the Rail Corner Armor for Jeep YJ

Shipping calculated at checkout.

Over the bed rail 15 inch stretch corners are a heavy duty option for those doing the LJ stretch on a Jeep YJ.  We opted to go over the rail on the Motobilt YJ build for a few reasons.  The first was a more complete finished look on the body stretch with the corners. We also wanted to add additional strength to the corner armor.  The corners are manufactured from 3/16” light weight aluminum plate. By adding 2 bends to the top edge and closing in the rear curve around the body we added a lot more protection for the body making the corner armor stronger than traditional designs.

Not only do the corners extend the body 15 inches we also moved the wheel opening up as high as possible to allow for lower bump heights and/or ride heights.  By doing so we needed the added material on the rear corner armor to ensure it would still have structure with that much material cut out. The rear corner area features a tapered cut for added clearance and styling. 

The rear tail lights are one of the features most asked about.  The aluminum bezels are on the outside of the corner armor with the taillights recessed into the body for added protection. The corner armor includes one pair of our pop in style LED tail lights and you also have the option to purchase a set of Off-Road Only Lite-Dots if you prefer those. The taillight mounts come complete with provisions to mount either style taillight you prefer. 

The wheel opening location provides approx a 16 inch wheelbase stretch from the stock YJ.  The wheel opening also has been enlarged for large diameter tires.  Keep in mind because the wheel opening has been moved as high as possible the stock height rear inner fender sheet metal will not work with the corners. We recommend using our YJ 15” Stretch High Line Rear Inner Fenders (MB5529) which can be purchased separately.

Keep in mind your rocker guards will also have to be extended to match the new wheel opening.  We offer two different options for 15” stretch rocker guards. For those looking for ultimate clearance you should check out the Motobilt boat side option. (MB1171)  Don’t worry we offer a bolt on style as well.  (MB1177 NO step) With either of the rocker guard options we include a plate with the corner armor to allow the installer to bolt the stretch corners to the stretch rocker guards. (MB1177-S With step)

Each corner armor panel features countersunk holes for fasteners for a completely flush panel. We include all fasteners & rivnuts for installation.

The 15" stretch over-the-rail corner armor for the YJ is also offered in steel, for those who plan to bash hard into things often.  Aluminum is lighter in weight, but is easier to scratch during manufacturing, installation and on the trail when you hit rocks and trees. Let us know if you have any questions and sales team will be happy to assist.
