Single Axle Install Using
Poly Fender Hardware Kit
‘Single hump’ style fenders are secured to the mounting tubes with our injection-molded, plastic nylon hangers. A mounting tube on the front and back attach the fender to the frame of the truck. Both of our kit styles include black, powder-coated, steel tubes. Here are a few key things to remember when installing:
Let the air out of your suspension before attaching fenders
Maintain a minimum 1.5″ space between tires and fenders
Don’t over-tighten tubes or set screws
Periodically check your setup for proper spacing and tightness
