The Poison Spyder Customs BFH bumper comes as unpainted, bare steel. You will want to either powder coat or paint the bumper prior to install. If painting yourself, careful preparation will make a big difference in the quality and longevity of your paint job, even using “rattle can” aerosol paints. Begin by thoroughly cleaning the bumper with solvent or de-greaser, then make sure all residue is removed. Even if you use cheap paint, try to use a good quality primer. “Etching” primers are best to use on bare, unpainted metal. Allow it to properly dry before painting, and between paint coats.

1. Park the Jeep on a flat, level surface and set the parking brake.

2. Remove existing front bumper.

3. Remove the “Crash Bar”. Use a torch, plasma cutter, pneumatic or electric cutoff wheel, reciprocating saw, or the cutting device of your choice. At each end of the Crash Bar there is a vertical bracket that attaches it to each frame rail. Cut these brackets off as close as possible where they meet the frame rail. Be careful not to cut INTO the frame rail.

4. Measure 2” back, along the frame rail, from the front edge of the OE bumper mounting bracket. Use a square and/or straight edge to mark a straight, perpendicular cut line at this 2” measurement.

5. Use a reciprocating saw or other suitable cutting device to cut the frame rails off, along the cut line you marked.

6. Use a grinder to de-burr the cut edges and smooth down the remnants of the crash bar brackets. You will need to get the outboard surfaces of the frame rails fairly smooth for proper fitment of the BFH bumper.

7. Apply primer and paint to the bare metal in the areas where you cut and grinded, including the cut edges of the frame rails. Properly coating these areas at this time will help to prevent rust in the future.

8. Remove the grille by opening the hood and removing the six (6) Phillips head screws along the top of the grille. Reach behind the grille and disconnect the headlight and turn signal lamp sockets. Remove the grille while carefully disengaging the snaps along the bottom edge of the grille.

9. Place the BFH Bumper on to the frame rails. Visually align the rearward, elongated bumper mounting slots with the existing holes in the frame rails. Take measurements to ensure that the bumper is installed square to the frame and grill, and centered in relation to the frame rails. Use a soft deadblow hammer, if necessary, to make fine adjustments. Use C-clamps or bar clamps to hold the bumper tightly in place.

10. Use a 1/2” drill bit and drill motor to drill the rearward hole in the bottoms of the frame rails by slipping the bit through the hole in the top of the frame rail and using it as your drill guide. Be careful to hold the drill as straight and perpendicular to the frame rail as possible. Install two of the supplied Grade 8 bolts, with lock nuts and flat washers, through the bumper and frame rails at these rearward holes.

11. Use the 1/2” drill bit and drill motor to drill the forward mounting holes through the frame rails, using the bumper itself as your drill guide. Drill the upper hole from the top and the lower hole from underneath. Do not try to drill both the top and the bottom through the same hole in the bumper, as you may not get the holes properly aligned. Install the remaining two of the supplied Grade 8 bolts, with lock nuts and flat washers, into these forward mounting holes.

12. Torque all four cap screws/nuts to 85 ft./lbs.

13. Re-install the grille by reversing the removal procedure from Step 8.

14. If installing the optional BFH Disco Skid, follow the instructions that came with the Disco Skid. If installing a winch with Poison Spyder Winch Fairlead Mount, follow the instructions included with the Winch Fairlead Mount.

Congratulations, you have installed your Poison Spyder Customs BFH front bumper!
