The following instructions should be used to mount the fifth wheel. Care and attention to detail will ensure a quick
quality installation. Check parts against parts list to become familiar with parts in kit.
CAUTION:
DO NOT install mounting rails over plastic bed liners. Plastic bed liners must be cut out of the way.
Base rails may be installed on dry/cured spray in liner. Note: Consult installer for recommended curing
time.

Use only the supplied bolts, nuts, and washers to install this kit. All nuts and bolts are Grade 5 unless specified

These instructions are guidelines only. Actual installation is the responsibility of the installer and
the owner. Always measure truck and trailer before installing hitch to be sure that there is clearance at
the cab and at the bumper to allow for turns.
