Expert Answers about GMC Sierra 2500


  • How to Raise Trailer Height When Axles are Already Under Leaf Springs
  • If you have already moved your trailer axle so that it sits below your leaf springs and you will still have 3" - 4" to go even after adjusting your 5th wheel hitch and pin box the most they can be adjusted then the only thing to do is swap out your hangers. You will need to have a professional welder cut off your current hangers and then you can use taller hangers like the Redline part # E4139 which is 4-1/4" tall. I have linked our selection of leaf spring hangers for you to filter through...

  • How to Install a B&W Sliding Hitch in a 2019 GMC Sierra 2500 w/out the Factory Tow Package
  • I have a couple of options for you. One will give you an under-bed gooseneck hitch the other will give you the ability to mount your B&W Patriot Slider item # BWRVK3270. There isn't an option to do both because the 5th wheel rail adapters that attach to the under bed system, like item # 16310, do not work with the Patriot slider. They sit too high in the center and the slider won't be able to move. To add an underbed system to your 2019 GMC Sierra 2500, I recommend the B&W Turnoverball...

  • Do I Need a Sliding 5th Wheel Hitch on a 2024 GMC Sierra 2500 w/ Factory Puck System?
  • Possibly since you have a 6-3/4' bed but you'll need to take a couple of measurements. I took a look at the nose of a 2024 North Point 310 RLTS. With how low of a profile it has and the kingpin extending out so far you should have plenty of clearance to the back of your cab using a standard 5th wheel hitch like the B&W Companion item # BWRVK3710. The formula to determine 5th wheel turning clearance is pretty straightforward and is expressed as: (A + B) - C = Clearance A = Distance from...

  • Can I Use an Adapter to Mount a B&W Patriot Slider in the Puck System of a 2023 GMC Sierra 2500?
  • No, there is not. There are two adapters that work with the GM factory puck and I have listed them below. Neither one are compatible with a B&W Patriot Slider item # BWRVK3270 due to how low the sliding portion is in relation to the mounting base. The sliding Patriot will hit the adapters. We had someone attempt to return an adapter with a huge dent in it from trying to get a Patriot to work. Adapter Rails for Curt 5th Wheel Hitch - Ford and Chevy/GMC Towing Prep Package item # C88KR Demco...

You will need the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter item # RP85FR. You will also need the Spacer Kit for Rotating Turret for 5th Airborne item # RP61301.

  • The Draw-Tite Front Mount Trailer Hitch Receiver - Custom Fit - 2" item # 65078 mounts below the tow hooks on your 2018 GMC Sierra 2500. All of the grille guards like the Aries Pro Series Grille Guard with Mesh LED Cover Plate - Textured Black Powder Coated Steel item # AAP4085 mount inside the frame where the tow hooks are mounted. The problem is they occupy the same space on the front end of your truck. The receiver would be blocked by the bar at the bottom of the grille guard. You will...

  • Towing Capacity of 2014 GMC 2500 for Gooseneck Trailer
  • Any vehicle's towing capacity is determined by the auto maker based on the specific equipment in it. Tow rating is determined by not just engine size, but also by the transmission, rear axle ratio, bed length and cab style. The surest way to know a vehicle's towing capacity is to find the driver's door jamb sticker. Find the GCWR (gross combined weight rating) and from this subtract the GVWR (gross vehicle weight rating). The difference is the maximum trailer weight that can be towed....

  • Can Hitch Box Extension and Reducer Handle 5,300 Pound Trailer
  • If I did the math right the combined weight of the trailer and the vehicle is 5,300 pounds.
