Pro Series Front Upper Control Arms

Designed with a focus on maximizing grip for racers and optimizing tire wear for lowered street vehicles, these arms provide a wide adjustment range for both camber and caster. Constructed from lightweight aluminum and titanium, these arms feature CNC-milled 6061 Billet Aluminum for superior strength and durability, validated by Finite Element Analysis (FEA). The arms incorporate a unique hex cap Double Adjuster system, crafted from electroless nickel-plated 4130 Chromoly and paired with 6061 Aluminum clamps to minimize weight and prevent corrosion. The design allows for quick and easy adjustments without the need for difficult-to-reach jam nuts. At the core of their performance are oversized, USA-made FK Spherical Bearings with a 3-piece Teflon liner. This setup ensures quiet operation, reduced friction, smoother articulation, and eliminates bushing deflection under load, offering robust reliability for both street and track use. The arms are further enhanced with offset chassis spacers to maximize caster adjustment and finished with a durable black anodization. They are sold as a pair.
