Adds Coverage (cm): 3.18 Adds Coverage (inch): 1.25 For extreme off-road use, there's nothing else like Bushwacker Cut-Out™ Fender Flares. Each set of Cut-Out™ Fender Flares is individually designed for your Jeep Grand Cherokee WJ, to maximize off-road wheel travel and maintain adequate tire coverage. That custom approach means a smoother appearance, greater strength, and easier bolt-on installation with tough stainless steel hardware. As the name says, Cut-Out™ Fender Flares require cutting body sheet metal to achieve maximum articulation and coverage for oversized tires (see the installation guide for your specific model for complete details). - See more at: http://bushwacker.com/fender-flares/jeep-cut-out-fender-flare-set-4-10926-07#sthash.QYnFCHpT.dpuf
