SPC Performance Adjustable Upper Control Arms, Early GM C10 Truck, Pair

These SPC Performance adjustable upper control arms are designed for early GM C10 truck applications and provide increased camber and caster adjustment compared to factory upper control arms. The adjustable design allows precise alignment tuning, making them ideal for lowered trucks, performance street builds, and suspension upgrades where factory alignment range is limited.

Improved alignment capability helps optimize tire contact, enhance straight line stability, and improve steering feel and return to center. These control arms are especially beneficial for early C10 trucks running modern wheel and tire combinations or modified ride heights while retaining the factory suspension layout.

Engineered for direct bolt on installation, these upper control arms are designed to work with factory style suspension components without permanent modification. Manufactured from high strength materials and built for durability, they provide a reliable solution for improving suspension geometry while maintaining street friendly drivability on classic GM truck platforms.
