Our ½-ton truck has relatively soft springs in the rear. To keep the rearend under control when towing or hauling a heavier load, we went to Summit Racing for a Hellwig antisway bar kit. The front sway bar is fairly large from the factory and does a decent job, but the Clunker needed some help in the rear. Hellwig is famous for heavy-duty sway bars and has been making retrofit kits for over 60 years. The kit is well designed and does its job well. However, there are a ton of parts, and the directions aren’t very helpful.
