25K ISR Adapter

The Demco 6333 is a rail adapter for GM 2500 and 3500 trucks with the factory OE puck system. It converts your pucks to industry-standard rails so you can mount any fifth wheel hitch with tabbed feet. Rated at 25,000 pounds gross trailer weight.

This adapter makes sense when you already own a fifth wheel hitch and your new GM truck came with pucks instead of traditional rails. Instead of buying a whole new puck-mount hitch, you install this adapter and keep using your existing equipment.

Installation happens from the truck bed using your factory puck locations. No drilling into the bed floor. The adapter locks into the pucks and provides standard rail spacing that works with virtually any fifth wheel hitch on the market.

Demco has been building towing equipment for nearly 50 years in the USA. They back this adapter with a five-year warranty. The heavy-duty steel construction handles serious trailer weights without issue.
