No — ARB part #3423140B is not the correct bumper for a GMC Sierra 2500HD. This bumper is specifically designed for the 2012–2015 Toyota Tacoma. ARB’s own fitment information confirms this application.
For a Sierra 2500HD, ARB does offer different vehicle-specific bumpers, but the correct part depends on the model year. For example, ARB #3462040 is listed for certain GMC Sierra 2500/3500HD applications.
If you can provide the year of your GMC Sierra 2500HD Crew Cab, we can confirm the correct ARB bumper for your truck.
