On vehicles with auxiliary lights, the auxiliary lights must be relocated. How the auxiliary lights are attached is up to the
vehicle owner, most commonly new mounting holes are drilled in the heavy-duty bumper for the auxiliary lights. No drilling
required for instillation of Rock Winch Bumper. Bolts on to both the top and bottom of the vehicle frame for extra security.
Ramsey and Warn Winches bolt right in. Mile Marker hydraulic winches requires minor grinding on rear support bar of
Rock Winch Bumper to allow for the hydraulic connection. Will not fit a Warn M8274-50 without modification. Standard
4.5” X 10” (254mm x 114.3mm) mounting holes are predrilled in the center super structure. Hardware for fairlead and
