Bushwacker Flat Style Fender Flares for Jeep Wrangler YJ
Our Bushwacker flat fender flares YJ are engineered to give your 1987–1995 Wrangler an aggressive, low-profile look while protecting the body from trail debris and oversized tires. The flat style eliminates the stock rounded lip for a clean, modern aesthetic that pairs perfectly with lifted suspensions and wider tire setups.
We mold every set of bushwacker flat fender flares yj from Dura-Flex 2000 thermoplastic olefin, a proprietary blend engineered to withstand decades of UV exposure, temperature swings from -40°F to 140°F, and repeated impacts from rocks and brush. Unlike ABS or cheaper polypropylene flares that become brittle and crack over time, TPO retains flexibility in freezing conditions and won't warp under summer heat.
Fitment and coverage for YJ Wranglers
The Bushwacker flat style is designed specifically for the 1987–1995 Wrangler YJ’s squared fender openings and wider track width compared to earlier CJ models. Each flare extends coverage approximately 1.75 inches beyond the stock fender lip, providing clearance for up to 33-inch tires on factory suspension or 35-inch tires with a 2.5-inch lift.
We engineered the mounting flanges to align with existing factory holes in the YJ’s inner fender wells, so installation requires no drilling, cutting, or permanent modification to the body. The flares sit flush against the fender edge and use concealed hardware for a clean, integrated appearance — no exposed bolt heads or visible mounting brackets.
Installation process and hardware
Each kit ships with pre-drilled flares, stainless steel bolts, washers, and rubber well nuts sized for the YJ’s specific mounting hole diameter. We include a paper installation template that overlays the fender opening to mark the correct hole positions if any factory holes have been covered by previous repairs or body filler.
Installation begins with test-fitting each flare to confirm alignment before drilling any pilot holes. Once positioned, you’ll use the provided bolts to secure the flare through the factory mounting points, tightening in a cross-pattern to ensure even pressure distribution. The rubber well nuts compress as you tighten, creating a weather seal that prevents water and debris from entering the fender cavity.

Common questions about Bushwacker YJ flat fender flares
No cutting is required. The Bushwacker flat style for the YJ bolts directly to existing factory mounting holes in the inner fender wells. The flares sit flush against the fender lip and cover the stock edge completely, so you retain the ability to return to factory appearance if you remove the flares later.
If you’re running extremely wide tires — 35 inches or larger on aggressive offset wheels — you may need to trim the inner fender liner for clearance at full suspension compression, but the outer sheet metal and fender opening remain unmodified.
Yes, the Dura-Flex TPO material accepts flexible bumper paint, automotive urethane, and spray-in bedliner coatings. Clean the flare surface with a wax-and-grease remover or isopropyl alcohol before applying paint — no sanding or primer is necessary if you’re using a product designed for flexible plastics.
Many owners also apply textured spray-on coatings like Herculiner or Raptor Liner to match the finish of their bumpers and rocker guards. The factory matte black finish is UV-stable and can be left unpainted if you prefer the out-of-the-box appearance.
On a factory-height YJ with no suspension lift, the flat style flares provide clearance for up to 33×12.50 tires on wheels with 4.5 inches of backspacing. If you’re running 31-inch tires or smaller, the flares will fully cover the tread width with room to spare.
With a 2.5-inch suspension lift and slightly less backspacing — around 3.75 to 4 inches — you can fit 35-inch tires under the flares without rubbing at full steering lock. Larger setups may require trimming the inner fender liner or adjusting bump stops to prevent contact during compression.
Most installers complete the job in two to three hours working alone with basic hand tools. The process involves test-fitting each flare, marking the factory mounting holes, and securing the flares with the included stainless steel hardware.
If your YJ’s factory holes are obscured by previous body repairs or undercoating, you may need an additional 30 minutes to locate and clean the mounting points. The included installation template speeds up the process by showing exact hole positions for the YJ’s fender openings.
Yes, the flat profile maintains adequate clearance for stubby front bumpers, full-width bumpers, and winch plates. The front flares do not extend forward far enough to interfere with bumper mounting brackets or approach angles on lifted YJs.
If you’re running a heavy-duty bumper with integrated light bars or fog light mounts, confirm that your specific bumper model leaves at least one inch of clearance between the bumper’s outermost edge and the fender opening — the flat style flares will not interfere with that gap.
We back every set of Bushwacker flat style fender flares with a limited lifetime warranty against defects in materials and workmanship. The warranty covers cracking, warping, and delamination under normal use but does not cover damage from collisions, improper installation, or modifications to the flares.
If a flare develops a manufacturing defect, contact our customer service team with photos and proof of purchase, and we’ll ship a replacement at no charge. The warranty is non-transferable and applies only to the original purchaser.
No, the rubber well nuts compress when you tighten the mounting bolts, creating a vibration-damping seal between the flare and the fender. The stainless steel hardware includes lock washers that prevent the bolts from loosening over time.
If you experience any rattling after installation, check that all bolts are tightened to the recommended torque spec — typically 10 to 12 foot-pounds for the YJ’s mounting points. Loose hardware is the most common cause of flare noise, and periodic inspections during routine maintenance will prevent the issue.
