BMR 70-81 GM F-Body / 75-79 GM X-Body Non-Adjustable A-Arm Kit - Red

The BMR Suspension AAK321R Front Upper and Lower A-Arm Kit (Red, Non-Adjustable, Delrin Bushings) is fabricated from heavy-duty 1.25-inch, 0.095-inch wall DOM tubing with laser-cut, CNC-formed plate steel braces. It eliminates A-arm deflection, improving steering feel and response. The kit includes CNC machined, nickel-plated, dual-offset cross-shafts with heavy-duty stainless bushing retainers, new polyurethane bump stops, and new upper ball joints. Upgraded Delrin bushings are internally fluted for even grease coating and quiet, reliable operation. It provides additional header clearance and 2 additional degrees of positive caster (combines with BMR Lower A-arms for a total of 4 additional degrees, up to 6 degrees total over stock) for increased high-speed stability and lateral grip. Upper arms have revised cross shaft geometry and shorter overall length for less shim stack to achieve negative camber.
