These rear inner fenders dress up the look of the Jeep's rear wheel wells with beautiful CNC laser cut, bead-rolled and brake-formed aluminum panels with inserts that may be painted a contrasting color. The main panels are made of 16 gauge 5052 aluminum. The CNC bead-rolled features look great and give the product a distinctive motorsports flare, but the beads actually help stiffen the product for further strength. These look great with Poison Spyder Crusher Flares, but they're a great addition to any Jeep JK Wrangler whether it still has stock flares, aftermarket plastic flares or other manufacturers' metal flares.
