About This Product
This fifth wheel hitch drops directly into factory OE pucks. No adapter needed. If your truck came with the fifth wheel prep package, you have pucks in your bed ready to accept this hitch.
The automatic mechanism slides the hitch when turning forces require clearance, returns it forward when you straighten out. No manual intervention.
Installation is more involved than fixed hitches. Once in, the convenience of automatic sliding is worth it for short bed owners.
For short bed trucks only. If you have a long bed, save the money and complexity with a fixed hitch.
