BMR on-car adjustable polyurethane upper control arms for 1979–2004 Fox-body Mustangs are built from heavy-duty 1-5/8" DOM tubing with a CNC-machined, chrome-moly center adjuster and TIG-welded tube adapters. Greasable 95-durometer bushings are internally fluted for lubrication and quiet operation, and the adjustability lets you fine-tune pinion angle for better driveline alignment in street, drag, or road race use.
