Modern radial tires demand alignment geometry that differs significantly from the bias ply specifications original equipment manufacturers used decades ago. SPC engineering recommends +3.00° of caster to enhance directional stability and steering response. First-generation Mustangs and comparable Ford vehicles came equipped with fixed caster rods featuring worn bushings that permit excessive play in the lower linkage, compromising handling precision. For '68–'73 Mustangs running contemporary tire compounds, this adjustable caster rod delivers the geometry correction needed for confident tracking and responsive feel. The rod incorporates reinforced elastomer bushings matched to OE standards, protecting frame attachment points while allowing straightforward caster tuning across a ±2.00° range. For drivers seeking adjustable camber capability as well, SPC's complete control arm assembly offers integrated adjustment at both angles.

Features and Benefits:

• Sold as matched pairs
• Reinforced Elastomer Bushings with Tool-Free Adjustment
• Caster Adjustment Range: ±2.00°
• One unit required per suspension corner
