SPC Performance G37/370Z Adj Control Arms Front

The SPC Adjustable Front Upper Control Arms are engineered for the Nissan 370Z and Infiniti G37 platform to provide extreme alignment flexibility and improved suspension performance. Designed for both street and performance applications, these arms allow up to ±4° camber and ±4° caster adjustment—one of the widest adjustment ranges available in the aftermarket.

Built from high-strength forged steel, the arms are optimized to reduce stress by directing loads into tension and compression, improving durability while minimizing weight. The turnbuckle-style adjustment system allows precise on-vehicle alignment changes without removal, making setup faster and more efficient.

SPC’s xAxis sealed flex joints combine the durability of rubber isolation with the responsiveness of a mono-ball design, maintaining factory-like noise, vibration, and harshness (NVH) levels while improving handling precision. The sealed construction protects against contamination and corrosion, extending service life in all driving environments.

These control arms are ideal for performance alignment setups, aggressive street builds, track use, and stance applications where camber correction or tire wear optimization is required.
