Magnumforce offers their tubular UCA (upper control arms) either with adjustable or bushed mounting points. The adjustable UCA comes with strong Teflon-lined heim joints. The bushed UCA are nonadjustable with pre-installed poly bushings. We chose the adjustable arms, which feature more available camber adjusting for better handling (road racing). The adjustable UCA also allows added positive caster that can aid in straight-line high-speed stability (drag racing). Either tubular UCA comes with the upper ball joint installed. We had ours powdercoated a subtle gray color.
