OE Puck System
Expert Take
This 18K Autoslide drops into factory pucks and slides back on its own during sharp turns, ideal for short-bed half-tons and three-quarter-tons. Good price for the safety feature, though install takes a bit more muscle and the ride is unremarkable.
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.
Same automatic mechanism - turning forces activate the slide mechanically. Nothing electronic to fail.
If your trailer is under 18K and you have a short bed, this saves money while delivering identical sliding performance.
For short bed trucks. Long beds do not need sliders.
