Quadratec Baja HD Fender Flares for your Jeep Wrangler JL work with your existing factory turn signal and DRL assemblies with small modifications. Flares provide the same tire coverage as the factory Rubicon flares that are 5/8” wider than the factory Sport flares giving adequate coverage for most oversized tire and wheel setups. Quadratec Baja HD Flares provide an additional 3” of vertical tire clearance over the factory Sport and Sahara flares allowing room for 37” tires with no suspension lift
