Premium Traction Bar Kit for GM 3500HD Long Bed

If your 3500HD long bed could talk, it’d probably ask for a little more control when you're laying into the throttle, or hauling something heavy down the highway. That’s where the McGaughys Traction Bar Kit steps in. Built specifically for the 2020–2025 Silverado and Sierra 3500HD long bed models, this kit is designed to lock down axle movement and eliminate wheel hop, giving you a more stable and responsive feel when it matters most. Whether you’re running a McGaughys lift or just want to tighten up the rear end of your truck, these traction bars add strength and style in one move. The bars come raw and uncoated, which gives you the freedom to paint or powder-coat them to match your build. Everything you need for installation is included, brackets, hardware, and a solid design that mounts directly to your truck’s frame and axle.
