Corner Guards for Jeep YJ, wheel cutout is moved back 4" to extend the wheelbase. Weight per steel corner guard: 30lbs (approx. 14kg) Weight per aluminum corner guard: 7lbs (approx. 3.2kg) FEATURES: Wheel opening is moved back (stretched) 4" to fit with our EXT gas tank (GST4002). Laser cut from 3/16" thick SOLID steel plate, just like our rock sliders. The 90 degree bend is formed with a single "hit" die on a CNC press brake to ensure this product matches the shape of your Jeeps tub. Stock wheel opening "shape" is retained (same) to still fit a standard TJ fender flare or the GenRight metal tube rear flare (TFR1000 or TFR1001) and remain street legal. Each set of panels has the factory mounting holes laser cut in for the tail lights, tailgate hinges and gas filler to make installation quicker. The mounting holes are pre-drilled and countersunk (we use 2 more mounting bolts than other brands) to secure the corner to the tub. Includes large 5/16" size countersunk Stainless Steel bolts (flush type) to securely mount our corners to protect your Jeeps tub and look clean! Fits on top of most 6” tall after market 3/16” thick rocker guards (rock sliders). Includes a new molded plastic fuel bezel to allow the 4" shift backward of the wheel opening.
