Take control of your rear suspension articulation and drivetrain alignment with the ICON 54100T Rear Upper Control Arm Kit. Designed for lifted 4Runners, GXs, and FJ Cruisers, this tubular upgrade unlocks articulation, eliminates bind, and delivers high-performance durability on and off the trail.
Built from 1026 DOM steel, these adjustable rear upper control arms feature PTFE-lined FK rod ends and multi-durometer bushings to provide the perfect mix of strength, adjustability, and quiet operation. Whether you're overlanding Utah sandstone or navigating a forest trail, ICON’s adjustable 4Runner rear upper links allow your rig’s suspension to cycle freely—without the slop or limitations of OEM arms.
ICON even added length adjustability so you can fine-tune pinion angle and driveline geometry after a lift. And since no grease is needed, these arms are set-it-and-send-it trail-tested with minimal maintenance required.

Why Upgrade?
When you're running larger tires, carrying gear, and pushing harder trails, factory rear upper control arms just can't keep up. These ICON tubular arms not only increase strength and clearance but also unlock articulation for maximum travel—keeping your suspension functioning like it should, no matter the terrain.
Whether you're chasing sunsets in Moab or just dialing in rear-end geometry after a lift, these arms let you do it with confidence.
