Forged Aluminum Upper Control Arms – Maximum Strength, Optimized for Lifted Performance

Upgrade your suspension the smart way with Rough Country’s strongest and most advanced Upper Control Arms yet. Designed for lifted trucks, these forged aluminum control arms offer unbeatable strength, superior articulation, and long-lasting reliability both on and off the road.


Built to Handle Anything

Crafted from a solid, one-piece forged aluminum body, these control arms are engineered for maximum structural integrity. Unlike welded steel arms, the forged construction eliminates weak points—ensuring long-term durability under extreme stress, heavy loads, and aggressive off-road use.


Engineered for Lifted Applications

Designed with a corrected ball joint angle, these arms maintain proper suspension geometry on lifted trucks, improving ride quality and component longevity while maximizing travel and articulation.


High-Performance, Maintenance-Friendly Ball Joints

Equipped with premium POM (Polyoxymethylene) ball joints, these arms deliver:

  • A larger ball diameter for improved wheel articulation

  • Low-friction polymer race for smoother motion and extended life

  • A fully greaseable design for easy maintenance and long-term performance


Quiet, Durable Operation

Each arm also includes OEM-style rubber bushings for a quiet, factory-like ride while maintaining long-lasting durability in all conditions.


Key Features:

Forged aluminum construction – lightweight, incredibly strong
One-piece design – no welds, no weak points
Corrected ball joint angle – ideal for lifted trucks
Greaseable POM ball joints – smooth, maintenance-friendly performance
Durable rubber bushings – quiet, reliable operation


Whether you're upgrading for performance or replacing worn-out factory parts, Rough Country’s Forged Upper Control Arms deliver the strength, precision, and quality your lifted truck deserves.
