If you are looking for the rear half of the fender kit, then you have come to the right place! Advanced Fiberglass Concepts created an aftermarket fiberglass rear quarter kit that is molded specifically for your Bronco and allows for larger tires without any rubbing issue. The quarter kit is handcrafted right here in America to ensure the highest quality, durability, and craftmanship. Advanced Fiberglass Concepts uses a proprietary blend of polyester resin that is paired with their fiberglass mat and cloth. The combination of resin and fabric provide the strength and flexibility you need for off-roading. Their products are designed to be long-lasting even during the toughest rides and climates.

The Advanced Fiberglass Concepts Rear Quarter Kit include a set of two quarter kits (driver and passenger side). The kit for the 4-door includes the rear quarter panels, door caps, and bumper caps. The kit for the 2-door includes the rear quarter panels and rear bumper caps. They come in your choice of 2” or 5” of coverage. The rise will be 1” on either option. They come standard in a paintable semi-gloss white finish. Color matching services are not offered but you can go to any local body shop in your area if you want to get it painted to match your factory color. The front fenders are sold separately. A professional installation is recommended for this product. Drilling is required.

Advanced Fiberglass Concepts LLC does recommend that a professional installs the rear quarter kit for a seamless fit. You will need a few hand tools and a few hours of time. Also, you will reuse most of your stock hardware during this installation—it is typical to have a few screws and bolts left over.

  • Tools required for most install:
  • Socket set
  • Drill and drill bits
  • Screw drivers (Flat head and Phillips)
  • 120 grit sand paper (optional)

Step 1: Open rear doors and remove soft/hardtop from your Bronco. Loosen and remove the two bolts holding the quarter panel at the rear door section. Loosen and remove the bolts at the bed rail. Uninstall the lower plastic rear bumper trim from the vehicle. Loosen and remove the bolts at rear bumper trim that are holding the rear quarter panel in place.
Step 2: Mount and tighten the rear quarter panel in position. Reinstall the rear bumper trim.
Step 3: Check all lines to make sure everything lines up correctly. Adjustments may need to be made to get correct body lines – such as sanding and repositioning the panel.
Step 4: Apply double sided tape the both the backside of the door caps and rear bumper trim. Press and hold the door caps and rear bumper trims in position against the vehicle.
Step 5: Approve all body lines and reinstall the soft/hardtop.
