Challenger Lifts truck adapter and extension kit, No. 10319, has combined two accessories for lifting trucks and other framed vehicles. Frame engaging adapters cradle the frame on vehicle and prevent slipping which could result in the vehicle falling off the lift. When lifting trucks or other framed vehicles, the use of these adaptors enhances safety. The package includes four frame engaging truck adapters, four 3" stack extensions, two 6" stack extensions, two organizer racks and associated hardware.
