Part #: 803-35-017

Overview

The FOX Billet Upper Control Arm (UCA) is a critical upgrade for Ram 1500 owners looking to enhance their truck’s off-road performance and suspension capability. Designed specifically for model years 2009 through 2025, including various engine configurations such as the 3.7L V6, 5.7L Hemi, 3.6L V6, 3.0L EcoDiesel, and the high-performance 6.2L TRX, this UCA is engineered to restore proper suspension geometry after a lift. It is the foundational step in building a mid-travel suspension system that unlocks greater articulation and control over rough terrain.

By addressing the alignment issues caused by lifting your Ram 1500, FOX’s billet upper control arms maintain optimal caster angles, improving stability and reducing wander at high speeds. This results in a more confident driving experience both on and off the road, with enhanced suspension droop for superior wheel travel and articulation.

Construction & Design

The FOX Billet Upper Control Arm is crafted from high-grade billet aluminum, offering an excellent strength-to-weight ratio that outperforms stamped or cast alternatives. This precision-machined component is engineered to withstand the rigors of off-road use while maintaining a lightweight profile to reduce unsprung mass. The design incorporates reinforced mounting points and durable bushings to ensure long-lasting performance and resistance to wear under demanding conditions.

FOX’s engineering team carefully evaluated the suspension geometry of the Ram 1500 to optimize the UCA’s shape and angles, ensuring it corrects alignment issues caused by lifts without compromising suspension travel or articulation. The vibrant orange finish not only provides corrosion resistance but also adds a distinctive look under the hood.
