Poison Spyder BFH™ II Rear Bumpers are designed for those hardcore four-wheelers who value strength, simplicity and function. This bumper was literally "Built For the Hammers" with the best ground clearance and departure angle possible. It is no wider than the JK rear body tub, with angled facets to improve its ability to slide over the rocks while still protecting the corner of the tub from drop-offs and ledges. This version of the BFH II features CNC machined high clearance recovery shackle tabs. For the ultimate in strength and durability, pair it with the JK BFH™ II Rear Crossmember. The BFH™ II Rear Bumper is CNC laser-cut from high strength 3/16" plate steel, then precision brake-formed for an exact fit. In keeping with its minimalist design parameter, the BFH™ II Rear Bumper has no provisions for a spare tire carrier. This bumper is intended for those hard-core wheelers who either wheel without a spare or strap the spare down into the bed of the Jeep. It may also be compatible with the OE tailgate-mounted spare tire carrier, depending on the size of the spare tire used. The faceted plate steel design of the JK BFH™ II Rear Bumper provides the most ground/obstacle clearance and best departure angle of any JK rear bumper on the market. To achieve this, installation requires trimming the bulky rear frame rails and stock bumper mounts.; A laser-cut steel template is provided to assist with making the right cuts. These modifications include cutting into the stock rear crossmember. At the installers discretion, the stock rear crossmember may be plated across the open cut (materials to do this are not included), or the crossmember removed completely. If the stock crossmember is removed completely, it may be replaced with the JK BFH™ II Rear Crossmember (note that there are versions of the BFH™ II Crossmember with or without a receiver hitch-this particular version of the BFH™ II Rear Bumper is specifically designed to work with the non-receiver version.
