Rubicon Express Super-Flex Control Arms

The Rubicon Express Super-Flex Control Arm line represents decades of proven off-road engineering, delivering the ideal balance of maximum suspension articulation and dependable on-road handling. Built from thick-wall DOM (Drawn Over Mandrel) steel tubing and finished with a durable powder coat for long-lasting corrosion resistance, these adjustable control arms are engineered to handle the harshest trail conditions without compromise.

At the heart of every Super-Flex Control Arm is Rubicon Express's signature rebuildable spherical bearing assembly. This precision joint is designed to provide unrestricted axle movement off-road while remaining quiet and predictable during everyday driving — no squeaking, no binding.

Super-Flex Bearing Technology:

• Rebuildable spherical bearing assembly for long-term serviceability and reduced ownership cost
• Polymer races encapsulating a hard-plated steel bearing for exceptional strength and quiet operation
• Non-metallic races eliminate squeaking and binding for a smooth, refined ride feel
• Threaded steel insert provides adjustable preload and simplified maintenance
• Greasable design extends service life and keeps the joint operating smoothly over time

Control Arm Construction:

• Thick-wall DOM steel tubing for exceptional rigidity and trail durability
• Powder-coated finish for corrosion resistance in demanding off-road environments
• Adjustable length for precise tuning of pinion angle, caster, and wheelbase geometry
• Available in upper and lower, front and rear configurations to suit a wide range of suspension builds

Whether used as a direct OE replacement, a geometry correction solution for a lifted suspension, or part of a complete suspension build, the Super-Flex Control Arm line gives Jeep enthusiasts the flexibility and durability to tackle any terrain with confidence. Rubicon Express backs this entire product line with a Lifetime Transferable Warranty, covering all components for the life of the vehicle — regardless of ownership.
