Bushwacker Flat Style Fender Flares for Jeep Wrangler TJ
Our flat style fender flares for the Jeep Wrangler TJ deliver maximum tire coverage with minimal overhang — designed for drivers who demand protection without bulky styling. Built from UV-treated Dura-Flex 2000 TPO, these flares resist cracking, warping, and fading even under relentless sun and trail debris.
We mold every Bushwacker flat fender flare from Dura-Flex 2000 thermoplastic olefin — the same impact-resistant material specified by OEM manufacturers for factory bumper covers and rocker panels. Unlike generic ABS plastic flares that become brittle after two summers, our TPO formula includes UV inhibitors blended at the molecular level during extrusion.
Flat Profile Geometry for 31″ to 33″ Tires
The flat style’s defining feature is minimal outward projection — these flares extend just 1.75″ beyond stock TJ wheel wells, compared to 3″ to 4″ for pocket-style or cut-out designs. That conservative stance preserves the Wrangler’s factory proportions while still providing legal fender coverage for tires up to 33″ diameter.
We designed the inner fender lip to clear aftermarket wheels with up to 4.5″ backspacing, accommodating popular TJ wheel combinations like 15×8 steelies or 17×8.5 alloys. The rear flares include relief pockets for full suspension articulation — your rear axle can cycle through 10″ of droop without tire contact during off-camber climbs.
No-Drill Installation Using OE Mounting Points
Every Bushwacker flat style kit for the TJ installs without cutting or drilling factory sheetmetal. We engineered the flare backs to align with existing Jeep mounting holes along the fender lip and wheel well edge — the same attachment points Chrysler used for the TJ’s original plastic cladding.
Each kit includes stainless steel bolts, washers, and speed clips sized for TJ body gauge. Front flares mount with eight bolts per side; rears use six. We also provide edge trim that snaps into the flare’s inner lip, sealing the gap between flare and body to prevent mud and water intrusion behind the panel.

Common Questions About Flat Style Fender Flares for TJ Wranglers
Flat style flares are engineered for tire diameters up to 33 inches with widths up to 12.5 inches. If you’re running 35-inch tires on a 4-inch lift, you’ll need our cut-out style flares, which provide 3.5 inches of extension and accommodate larger tire diameters. The flat profile’s 1.75-inch extension will not provide full DOT-compliant coverage for 35-inch meats, especially on wheels with aggressive backspacing.
No body drilling is required. Bushwacker flat style flares mount using the Jeep Wrangler TJ’s existing factory attachment points along the fender lip and wheel well edge. You will drill pilot holes in the flares themselves to match these OE mounting locations, but the Jeep’s sheetmetal remains unmodified. This allows you to remove the flares later without permanent body alteration if you sell the Jeep or change your setup.
Yes. The Dura-Flex 2000 TPO material accepts flexible bumper paint when properly prepped. We recommend scuffing the flare surface with 320-grit sandpaper, applying a TPO adhesion promoter like SEM 39863, and using flexible automotive paint designed for plastic bumpers. Standard enamel or urethane paints without flex additives will crack as the TPO flexes during temperature changes. Most professional body shops can color-match and paint the flares for $200 to $400 per set.
Bushwacker flat style flares accommodate wheels with 3.75 to 4.5 inches of backspacing when running tire widths up to 12.5 inches. This covers most common TJ wheel setups including 15×8 steelies with 3.75-inch backspacing and 17×8.5 alloys with 4.5-inch backspacing. Wheels with less than 3.75 inches of backspacing will push the tire outward beyond the flare’s coverage zone, potentially causing DOT compliance issues.
Most TJ owners complete a four-flare installation in 90 minutes to two hours using basic hand tools. The process involves positioning each flare using the included template, drilling pilot holes through the flare to align with factory body mounting points, and bolting the flares in place with the provided stainless steel hardware. Front flares require eight bolts per side; rear flares use six. No cutting, grinding, or special tools are needed beyond a drill, 10mm and 13mm sockets, and a tape measure.
Bushwacker flares are molded from Dura-Flex 2000 TPO with UV inhibitors blended at the molecular level. Independent ASTM G154 accelerated weathering tests show zero cracking or chalking after 2,000 hours of simulated UV exposure, equivalent to five years of full-sun parking in desert climates. The material’s flexural modulus remains stable through freeze-thaw cycles, and our lifetime warranty covers any UV-induced finish defects or structural damage from sun exposure.
Yes. These flares meet Federal Motor Vehicle Safety Standard 571.108, which requires fenders to cover the full tire tread width when viewed from above. The flat profile’s 1.75-inch extension provides compliant coverage for tire widths up to 12.5 inches, making them legal in all 50 states for TJs running 31-inch to 33-inch tires. If your state requires annual safety inspections, these flares will pass fender coverage requirements as long as your tires fall within the specified width range.
