GM/Chevy Puck System

Factory fifth wheel prep on Chevrolet Silverado and GMC Sierra HD trucks.

What is GM's Puck System?

GM's factory fifth wheel/gooseneck prep package installs mounting points in your truck bed that accept drop-in hitches. Same concept as Ford and Ram — easy installation, no drilling, clean bed when not towing.

Which GM Trucks Have It?

HD models with the prep package

Chevrolet

  • • Silverado 2500HD
  • • Silverado 3500HD

GMC

  • • Sierra 2500HD
  • • Sierra 3500HD

Important

The puck system is an optional package. Not all HD trucks have it. Check your truck before ordering a puck-mount hitch.

What's It Called?

Look for these on the window sticker

  • • Fifth Wheel/Gooseneck Prep Package
  • • Gooseneck/Fifth Wheel Hitch Platform
  • • Hitch Platform (with bed provisions)

GM's package often includes the prep provisions plus an actual hitch or ball. Check what's included — you might already have hardware.

How to Identify GM Pucks

Visual check

Look in the front half of your truck bed for the mounting points.

GM Puck Layout:

  • • Four pucks arranged in a rectangle
  • • May have covers or be recessed
  • • Located toward front of bed
  • • Some years also have a center gooseneck provision

GM's pattern is similar to but not identical to Ford's. Most aftermarket hitches fit both, but verify compatibility for your specific year.
