The CrawlTek Revolution Inferno Highline Fender is designed to give you maximum room for large tires. With a stock wheelbase you can run a 40" tire with no worry of hitting the fender near the tub. We included the battery relocation trays that fit with stock and aftermarket batteries. The inner fender liners (included) are made of aluminum and allow for plenty of heat to escape. Simply cut your factory hood or use an aftermarket highline hood!
