Poison Spyder's DeFender XC's provide eXtreme Clearance for big tires without having to install a tall lift, maintaining a Low Center of Gravity (LCOG) and the performance benefits that come along with it. Like our standard DeFenders, the XC's are constructed entirely of CNC laser cut, brake-formed 3/16" plate steel or aluminum for strength and style that old school tube fenders just can't match. JUMP TO:Top of Page | Product Description | Image Galleries | Features & Benefits | Frequently Asked Questions | Related Products Product Description Massive Tire Clearance Standard DeFender provide much better tire clearance than stock or some competitors' tube fenders, but DeFender XC's provide eXtreme Clearance!. Like with the standard DeFenders, the back of the wheel opening is approximately 2½" further back compared to typical tube fenders, and about 4" further back than the stock Jeep flares. But the wheel opening on the XC's is 3" higher than standard DeFenders, providing Massive Tire Clearance with minimal lift! While there are specific considerations to address with any particular Jeep, in most cases you should be able to run 37" tires with no suspension lift, and 40's with just couple inches of lift!
