BMR Pro-Touring Tall Ball Joint Tubular Upper A-Arms (AA027H) - 67-69 F-Body / 68-74 X-Body
A-arms are one of the most important, yet overlooked suspension components, serving as the direct link between the front wheels and the chassis. Any deflection causes a change in alignment, which results in poor performance and driving feel. Fabricated from heavy-duty 1.25-inch, 0.095-inch wall DOM steel tubing with laser-cut, CNC-formed plate steel braces, deflection is completely eliminated with upper A-arms from BMR Suspension. BMR's AA027 arms come equipped with CNC-machined nickel-plated dual-offset cross-shafts, stainless bushing retainers, new upper ball joints, and polyurethane bump stops.
Engineered for pro-touring, street performance, drag racing, and handling applications, the AA027H upper A-arms feature tall ball joints to drastically improve the camber curve and maximize tire contact patch during hard cornering. These arms include two additional degrees of positive caster, revised cross-shaft geometry, and a shorter overall length to require less shim stack for aggressive negative camber alignments while providing extra header clearance. Finished in a durable black hammertone powdercoat, installation typically takes 3–4 hours.
Note: Control arm hardware kit RH006 (includes upper and lower control arm hardware) is highly recommended for complete installation.
