Lower Arms 70-81 GM F-Bo dy

The SPC Performance Lower Arms 70-81 GM F-Body control arms deliver OEM-quality suspension geometry for classic Chevrolet muscle cars and street machines. Manufactured as a matched pair, these tubular lower arms restore proper wheel alignment and suspension compliance in Camaro, Firebird, and full-size F-Body platforms from 1970 through 1981. Built from steel construction with steel bushings and finished in black paint, these arms withstand the demands of both street driving and track use without sacrificing authentic appearance.

Tubular design combines structural rigidity with weight savings compared to stamped factory arms. The steel/plastic bushing configuration balances durability with vibration isolation—a proven arrangement in OEM and performance applications. Each arm measures precisely to specification, ensuring proper roll geometry, camber curve, and suspension travel. The black paint finish resists corrosion and integrates seamlessly with undercarriage restoration work. At 35.3 lbs per pair, these arms are substantial enough for reliable long-term use without excessive unsprung mass.

Classic F-Body owners restoring original suspension geometry—whether pursuing concours-level authenticity or improving street handling—depend on dimensionally accurate control arms to eliminate binding and restore proper wheel motion. These SPC Performance units suit full restorations, suspension upgrades, and replacement applications where OEM fitment and durability are non-negotiable. The pair configuration eliminates the need to source matching arms separately and guarantees left-right symmetry critical for balanced suspension dynamics.

F-Body suspension components from this era frequently exhibit wear in the bushing materials and control arm bending from hard use. SPC Performance control arms provide a direct replacement path that maintains factory appearance while restoring suspension response. Buyers installing these arms should verify wheel alignment afterward to confirm geometry matches their specific vehicle configuration and desired driving characteristics.
