NOTE: TWO PEOPLE WILL BE NEEDED TO MOUNT THIS BUMPER.
(Step 1):
Remove original factory bumper per manufacturer's instructions. The lower mounting bolts
can be reused if desired.
(Step 2):
The inner mounting holes on the Rock Crawler bumper will not align with any factory holes
regardless of model year (Fig.1). With the help of another person mount the bumper using the
outer holes only. With bumper secured scribe or mark the inner hole locations. (Fig.2)
Be sure to mark hole location correctly for proper fitment. Remove bumper and set aside.

(Step 3):
With the holes marked or scribed drill a small 3/16" pilot hole in the rear cross member in the
center of your marks. The smaller pilot hole insures the centering of your larger mounting
hole when drilled.
CAUTION: EXTREME CARE SHOULD BE TAKEN BEFORE DRILLING.
THE FUEL TANK IS LOCATED JUST BEHIND THE CROSS MEMBER.
Great care will be
needed to avoid damaging the fuel tank.
With the smaller 3/16" pilot holes drilled, enlarge the holes using a 1/2" drill bit.
AGAIN, BE CAREFUL AND AVOID ANY CONTACT OF THE DRILL BIT TO FUEL TANK.
