Bushwacker Flat Style Fender Flares — Jeep Wrangler JK
Our Flat Style fender flares for the Jeep Wrangler JK deliver the low-profile coverage serious off-roaders demand without overwhelming the JK’s iconic body lines. We designed these flares to follow the factory fender contour while adding 1.5 inches of tire coverage per wheel, protecting your paint from trail debris and mud without the bulk of traditional wide-arch styles.
We mold every Bushwacker flat fender flare for the Jeep JK from Dura-Flex 2000, a thermoplastic olefin compound engineered to flex on impact rather than crack. This material absorbs trail strikes from rocks and branches, then returns to its original shape without permanent deformation — a critical advantage over rigid ABS plastic flares that shatter on hard hits.
Fitment & tire clearance for JK models
These Flat Style flares fit all 2007-2018 Jeep Wrangler JK models, including both the two-door Sport/Sahara/Rubicon and the four-door Unlimited variants. The mounting pattern is identical across the entire JK generation, so the same four-piece kit serves both wheelbases without modification.
Coverage dimensions
Each flare extends 1.5 inches beyond the factory fender lip, measured at the widest point of the wheel opening. This coverage accommodates up to 35-inch tires on a stock suspension with minimal trimming, or 37-inch rubber on a 2.5-inch lift with minor inner fender work. Backspacing between 4.5 and 5 inches keeps the tire centerline inside the flare edge on most wheel-and-tire combinations.
Installation process & hardware
We include everything you need to mount these flares in the kit: stainless steel bolts, washers, and speed nuts sized for the JK’s factory fender holes. Most installations on 2007-2018 Wranglers require no drilling — the flare mounting holes align directly with existing threaded inserts or clip locations on the fender.
Step-by-step overview
Start by removing the factory Jeep fender liner fasteners (push-pin clips on most models) and folding the liner back to expose the inner fender surface. Position the flare against the outer fender, aligning the pre-drilled holes with the factory mounting points. Thread the provided stainless bolts through the flare, fender, and inner liner, then hand-tighten the speed nuts on the backside.

Questions about Bushwacker Flat fender flares for JK
No drilling is required on most 2007-2018 Jeep Wrangler JK models. The flares mount using existing factory fender holes and threaded inserts, with all necessary stainless steel hardware included in the kit. A small number of Sport and Sahara trim JKs may require one or two additional holes if the factory fender was not pre-punched for accessory flares, but this is rare and clearly noted in the included instructions.
Installation involves removing the existing fender liner clips, positioning the flare over the factory mounting points, threading the provided bolts through the flare and fender, and securing the hardware on the backside. The entire process takes about 90 minutes for a first-time installer with basic hand tools.
Bushwacker Flat Style flares add 1.5 inches of coverage per wheel beyond the factory JK fender lip. This accommodates up to 35-inch tires on a stock suspension with minimal to no trimming, depending on wheel backspacing. With a 2.5-inch or taller lift, you can clear 37-inch tires, though some inner fender liner trimming may be necessary at full articulation.
For optimal fitment with 35-inch tires, run wheels with 4.5 to 5 inches of backspacing. More aggressive offsets (lower backspacing numbers) push the tire outward and may require additional trimming or a wider flare style like our Extend-A-Fender kit.
Yes, the same Bushwacker Flat Style fender flare kit fits both the two-door Jeep Wrangler JK and the four-door Unlimited JK models from 2007 through 2018. The mounting points and fender contours are identical across both wheelbases, so you order one kit regardless of your JK variant.
The kit includes front and rear flares for a complete four-piece installation. Rear flares are the same length for both two-door and Unlimited models, as the fender opening size did not change between configurations.
Yes, you can paint Bushwacker Flat Style flares to match your JK’s body color. The Dura-Flex 2000 TPO material accepts automotive paint when properly prepped with a plastic adhesion promoter. We recommend scuffing the surface with 320-grit sandpaper, applying a dedicated TPO primer, then spraying your color coat and clear.
Many JK owners leave the flares in the factory matte black finish, as it complements the Wrangler’s trim and creates a two-tone look that hides trail scratches. If you choose to paint, note that rock strikes and branch contact on the trails may chip the paint over time, requiring periodic touch-ups.
Yes, when properly installed, Bushwacker Flat Style fender flares for the Jeep Wrangler JK comply with fender coverage laws in all 50 states. Most state regulations require fender coverage to extend at least to the widest point of the tire tread when viewed from above, and these flares provide 1.5 inches of extension beyond the factory JK fender.
For Wranglers running oversized tires, the flares ensure the top arc of the tire remains covered as required by law, preventing citations for inadequate mud flap or fender coverage. Always verify your specific tire and wheel combination stays within the flare’s coverage area by checking clearance at full steering lock.
Bushwacker Flat Style flares offer a low-profile, OE-contoured look with 1.5 inches of tire coverage, while Pocket Style flares add bold rivet detailing and typically extend 2 inches or more. Flat Style sits closer to the body and blends with the factory fender line, making it the subtle option for JK owners who want coverage without a heavily modified appearance.
Pocket Style includes exposed stainless steel bolts that create an aggressive, armor-plated aesthetic and provide slightly more tire clearance for larger rubber. Both styles use the same Dura-Flex 2000 material and carry our lifetime warranty, so the choice comes down to your preferred look and tire size.
Yes, every set of Bushwacker Flat Style fender flares is backed by our limited lifetime warranty against cracking, warping, and UV-induced fading or discoloration. The warranty covers defects in materials and workmanship for as long as you own the Jeep on which the flares are originally installed.
The warranty does not cover damage from collisions, improper installation, or modifications to the flares after purchase. If a flare develops a manufacturing defect, we will replace it at no charge. Registration is not required, but we recommend keeping your purchase receipt for warranty claims.
