SPC Performance Adjustable Upper Control Arms, GM A Body, Pair

These SPC Performance adjustable upper control arms are designed for 1964-72 GM A Body applications and provide significantly increased camber and caster adjustment compared to factory control arms. The adjustable design allows precise alignment tuning, making them ideal for performance street builds, lowered vehicles, and suspension upgrades where factory alignment range is limited.

By improving alignment capability, these control arms help optimize tire contact, enhance cornering stability, and improve steering feel and return to center. They are especially beneficial for vehicles running wider tires, modern wheel and tire combinations, or upgraded suspension components.

Engineered for direct bolt on installation, these upper control arms are designed to work with factory style suspension layouts without permanent modification. Manufactured from high strength materials and built for durability, they offer a reliable solution for restoring proper suspension geometry while allowing modern alignment settings on classic GM A Body platforms.
