Frame: Description and Operation
FRAME AND BODY MOUNTINGStructural Enhancement:
The frame consists of 2 steel channel rails, a front crossmember, transmission support crossmember and a rear crossmember (trailer hitch). The side rails and welded crossmembers are not installed separately. A front frame rail repair kit is available if the front rail is to be repaired.
Frame-Mounted Heat Shields
The frame-mounted heat shields are attached to the top of the frame and crossmembers with bolts. The body must be lifted off the frame enough for access to the bolts that attach the heat shields to the top of the frame.
The purpose of this insert is to enhance the structural rigidity of the frame in this area. The insert cannot be installed new or repaired.
