Finally a Frame Channel Stiffener Plates for the Jeep WK / XK Platforms. These are made from 3/16" plate steel and weld to your frame channel to stiffen up the chassis and keep the rocks from destroying your frame. They come as a pair left and right. They have a 90 degree bend at the floor to keep from making a stress riser at the floor transition. These greatly strengthen the frame assembly. These are required when adding longer lower control arms as the thin sheet metal does not have the strength for the stresses of welding a new lower mount frame. These are profiled on the drivers side so the stock fuel tank and skid still bolt up with out interference.
