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 for strength and style that old school tube fenders just can't match. The DeFender XC's provide eXtreme Clearance! Like with the standard DeFenders, the back of the wheel opening is approximately 21/2" 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! The DeFender XC with 3" Tapered Flare was designed for maximum performance in several aspects. First, it provides the same splash protection of our regular 3" flare, keeping mud and debris from splashing up onto the side of the Jeep. But rather than having a straight side, the edge of the flare tapers inward toward the front of the Jeep, in a line parallel to the tapered edge of the hood. In this manner it tapers from 3" at the back, to about the same width as our "Zero Flare" at the front, providing the same great clearance for articulating tires and tight trails that our Zero Flare provides. This Fender will require modification to the factory hood and Poison Spyder's DeFender XC Inner Fenders #PSC14-02-099 to complete installation.
