Abstract: A seat lift kit is used for raising the bench seat in the back of an extended cab pick-up truck. The kit includes a pair of channel shaped bench brackets that bolt directly to the existing seat bench and bench mounting holes on the cab floor and a similar pair of channel shaped seat back brackets. The back brackets carry an angle section that supports the rear edge of the seat bench. The seat back is retained in an upright position with a hook and loop pile fastener with one component secured to the truck cab and the other to the seat back. The seat belts are extended using angled extension bars. In preferred embodiments, the seat bench and the bottom of the seat back are moved forwards so that the seat back slopes upwardly and to the rear, making the seat more comfortable for the occupant.
