BMR on-car adjustable polyurethane upper control arms for 1979–2004 Fox-body Mustangs in red use heavy-duty 1-5/8" DOM tubing, a CNC-machined chrome-moly adjuster, and TIG-welded adapters. Two-inch greasable 95-durometer bushings with internal flutes retain grease for quiet operation, and the adjustable design allows pinion-angle tuning for improved driveline alignment in street, drag, or road race environments.
