Bolster Your Frame Your stock Polaris Ranger frame is only made to withstand so much. When you load it up with a big lift kit, portals, a RIDE System Rear Steering Kit, you need to reinforce your frame. Get SuperATV™s front or rear Frame Stiffener to bolster your machine, save your chassis, and ride like mad. Go BIG With SuperATV's frame stiffener installed, you can strengthen those OEM weak spots on your chassis and go as big as you want without worrying about bending your frame. Want 8" portals? Go for it. A 6" lift? Or, just get both, slap on some huge tires, and hit the gas”our frame stiffeners can handle anything you throw at them and then some. Do You Need a Front or Rear Frame Stiffener? Which gusset kit will reinforce your Ranger the best? It depends on what you™re doing. If you™re lifting your machine, go with a front frame stiffener. If you™re adding a RIDE System Rear Steering Kit, get a rear frame stiffener. If you decide to live the dream with a rear steering kit and a big lift kit, get both! NOTE: When running the Polaris Ranger XP Frame Stiffener / Gusset Kit with the Polaris Ranger Full Size Skid Plate, the frame stiffener will replace the front section of the skid plate.
