About This Fender Flare Trim

Fender flare trim, measuring .379” x .273” x.125”.

Trim-Lok’s Fender Flare Trim mounts between the fender flare and the body to protect your vehicle by minimizing vibrations and gaps. Made of an ozone-resistant EPDM edge trim dense rubber, this fender flare molding is flexible enough to fit most fender flares. A 3M automotive grade peel-n-stick tape creates a solid bond between both surfaces.

Trim-Lok’s fender flare edge trim is easily attached before the fender flare is installed against the body of the car or truck. Whether you need to replace your worn-out fender flare molding or you're replacing your fender flares, fender molding trim helps the fender flare fit tightly against the vehicle body to minimize vibration, reduce gaps and provide an attractive finish.
