Cusco 1A1-474-L Adjustable Rear Upper Control Arm

The Cusco 1A1-474-L Adjustable Rear Upper Control Arm is an engineered suspension upgrade designed to provide precise rear camber adjustment and improved handling characteristics. This performance component is essential for enthusiasts running lowered suspension setups with wider wheels and tires.

Key Features:

• Adjustable turnbuckle design with +15mm to -8mm camber adjustment range (23mm total adjustment)
• High-strength steel construction for maximum durability and impact resistance
• Hard rubber bushing design eliminates unwanted alignment changes
• Direct OEM replacement for easy bolt-on installation
• Corrects suspension geometry on lowered vehicles
• Enables proper tire contact patch for improved cornering and traction
• Prevents irregular tire wear caused by improper camber angles

When lowering a vehicle or installing wider offset wheels, the factory suspension geometry can be compromised, leading to off-center loading, poor tire wear, and reduced handling performance. The Cusco adjustable rear upper arm solves these issues by allowing fine-tuned camber adjustments to maintain proper suspension geometry. The turnbuckle adjustment mechanism makes it easy to dial in the perfect setting for your specific setup, whether for street performance, track use, or motorsports applications. The hard rubber bushings provide responsive steering feel while maintaining alignment stability under load.
