Expert Reply:
Hey Quinn. The installation time for the Hellwig Adjustable Big Wig Rear Anti-Sway Bar item # HE96XR ranges from 1-1/2 to 3 hours depending on experience and access to a lift. Plus it depends on whether or not you have to remove a factory sway bar and all the brackets.
The Big Wig Rear Anti-Sway Bar item # HE96XR has been confirmed to fit the 2025 GMC Sierra 3500. It is 1-5/16" in diameter and includes all the required installation hardware, along with end links, to complete the installation.
Are you towing a trailer or hauling a camper in your bed? What has you adding the sway bar to your truck?
