What is a Puck System?
The short answer: Your truck might already have the best mounting system built in. Here's what puck mounts are and why they matter.

The Short Answer
A puck system is a set of four mounting points built into your truck bed from the factory. Instead of drilling holes and bolting in rails, you just drop a compatible hitch into the pucks and you're ready to tow.
How Do I Know If My Truck Has a Puck System?
Check your truck bed
Look in your truck bed. If you have a puck system, you'll see four round covers (or open holes) arranged in a rectangle pattern. They're usually located in the front half of the bed, roughly between the wheel wells.
What to Look For:
- • Four round holes or covers — About 4 inches in diameter, arranged in a rectangle
- • Location — Front half of the bed, between the wheel wells
- • Window sticker terms — "Fifth Wheel Prep Package," "Gooseneck/Fifth Wheel Prep," or "Factory Puck System"

Which Trucks Have Puck Systems?
Heavy-duty trucks from the Big 3
Most heavy-duty trucks from Ford, GM, and Ram offer a factory puck system as an option. It's usually part of a towing package or prep package.
Ford
F-250, F-350, F-450 Super Duty trucks with the "Fifth Wheel/Gooseneck Hitch Prep Package"
Chevrolet/GMC
Silverado/Sierra 2500HD and 3500HD with the "Fifth Wheel/Gooseneck Prep Package"
Ram
Ram 2500 and 3500 with the "Fifth Wheel/Gooseneck Prep Group"
Each brand's pattern is a little different — and the spacing even changed by year. Dig into your truck: Ford, GM (Chevy/GMC), or Ram — or compare them side by side in Puck System Dimensions & Fitment.

What Hitches Work With Pucks?
Three options
Drop-In Fifth Wheel Hitches
These are 4-point fifth wheel hitches — they plug directly into your pucks (four points of connection). Brands like B&W Companion and CURT Q-Series are popular choices. This is the easiest option if you're towing a fifth wheel trailer.
Gooseneck Ball Adapters
These convert your pucks to a gooseneck ball. From there you can run a single-point fifth wheel hitch (like the PullRite 3900, which mounts to the ball and keeps your trailer's kingpin), or swap your trailer's pin box for a gooseneck pin box. Great for a flush ball and a clean bed.
Puck-to-Rail Adapters
These give you standard rails on top of your pucks, opening up compatibility with any rail-mount fifth wheel hitch. More options, but adds some height and complexity.

What If My Truck Doesn't Have Pucks?
No problem
If your truck doesn't have the factory puck system, you have two main options:
Install Aftermarket Rails
Universal mounting rails bolt into your truck bed and work with rail-mount hitches.

Some kits include rails and a hitch together for a simpler purchase.
