Dial in front-end alignment with the Mevotech Supreme Alignment Caster / Camber Bushing MK8977, a front-position bushing that lets you adjust caster and camber angles back into specification. It's a direct-fit alignment component for a wide range of Ford and Mazda trucks and vans, including the 1991-1994 Ford Explorer, 1987-1996 Ford F-150, 1987-1997 Ford F-250, 1989-1990 Ford Bronco II, 1989-1997 Ford Ranger, 2000-2005 Ford Excursion, 1999-2018 Ford E-350 Super Duty, and the 1994-1997 Mazda B2300 and B4000 — see the Buyer's Guide tab for the full list of 37 applications and the specific engines.
Installed at the front suspension, it repositions the pivot to bring caster and camber into a correctable range, which helps address off-center steering and uneven or edge tire wear when the alignment has drifted out of spec.
If worn or out-of-spec alignment is the cause of your tire wear or steering pull, this bushing provides the adjustment needed to reset the front angles. Have the front end aligned after installation.
