S&B Billet Radius Arms are machined out of billet 6061 aluminum for optimal strength and weight. These fit all 4wd 2005-2022 Super Duty Trucks. They also provide better tire clearance than factory arms due to their overall thickness. The arms include adjustable caster cam bolts for complete caster control during the alignment process as well as a mounting tab for our 105048 limit strap kit that is required with some shock packages.
