BUILT FOR LIFTED 4RUNNERS & FJ CRUISERS
Old Man Emu Upper Control Arms | Toyota 4Runner 2005-2023 & FJ Cruiser 2007-2014
A suspension lift changes more than ride height. It changes suspension geometry.
When an independent front suspension 4Runner or FJ Cruiser is lifted, factory caster and camber adjustment can be pushed beyond the range Toyota originally designed into the vehicle. That can make achieving proper alignment difficult and compromise steering feel, suspension movement and tyre wear.
The Old Man Emu UCA0004 Upper Control Arm Kit is engineered specifically to correct that problem, restoring usable caster and camber adjustment while providing the strength, clearance and articulation expected from a properly engineered lifted suspension system.
WHY UPGRADE THE UPPER CONTROL ARMS?
Lifting the Vehicle Is Only Half the Job
The factory 4Runner and FJ Cruiser upper control arms were designed around factory suspension height. Raise the front suspension and the relationship between the chassis, steering knuckle and control arm changes with it.
Old Man Emu engineered the UCA0004 with increased caster and camber correction for a 50 mm (approximately 2") suspension lift, helping bring the alignment adjustment back into an acceptable range.
The result is a suspension system that works together rather than simply sitting taller, with proper alignment capability, increased clearance and improved freedom of movement for upgraded suspension components.
Engineered as Part of the Suspension System
Corrected Suspension Geometry
Increased caster and camber correction helps restore usable alignment adjustment after lifting the 4Runner or FJ Cruiser.
Forged Construction
Forged ball joint housings and forged eyelets provide strength where suspension loads are concentrated.
GIIRO® Bushings
Free-pivoting, grease-free and maintenance-free bushings allow smooth control-arm movement without routine lubrication.
Heavy-Duty Ball Joint
A greaseable heavy-duty ball joint is protected by an OME ball joint cap for durability in demanding road and trail conditions.
More Clearance & Travel
The upgraded control-arm design provides additional clearance for larger coilovers and allows greater suspension travel when used with compatible longer-travel suspension.
Designed for OME Suspension
Engineered to complement Old Man Emu suspension systems and OME GVM upgrades rather than treating the control arm as an isolated suspension component.
THE REAL-WORLD DIFFERENCE
Build the Suspension to Drive Properly, Not Just Sit Higher
A lifted 4Runner or FJ Cruiser still spends plenty of time on pavement. Steering response, alignment and predictable handling matter just as much on the highway as suspension travel does on the trail.
That's why an upper control arm upgrade makes sense as part of a properly engineered suspension build. The objective isn't simply clearance. It's getting the geometry back where it belongs so the upgraded suspension can perform the way it was intended.

VEHICLE FITMENT
Toyota 4Runner 2005-2023 & FJ Cruiser 2007-2014
UCA0004 is designed for the following Toyota applications:
- Toyota 4Runner: 2005-2023
- Toyota FJ Cruiser: 2007-2014
Have a 2025+ 4Runner? The sixth-generation Toyota 4Runner uses the newer Old Man Emu UCA0037 upper control arm. UCA0004 is not the correct application for GEN6 trucks.
Suspension geometry and clearances should be checked during installation, followed by a proper wheel alignment. Vehicles using oversized tyres, aftermarket wheels or additional suspension modifications should also be checked for adequate clearance throughout the suspension and steering range.
THE CAP-IT TAKE
If You're Building the Suspension, Finish the Suspension.
It's easy to spend the budget on shocks and springs because those are the components everyone associates with a suspension upgrade. But once the front of an IFS 4Runner or FJ Cruiser is lifted, geometry becomes part of the equation.
That's particularly important on vehicles being built for real-world use, where they need to be comfortable and predictable during the drive to the trail as well as capable once they get there.
For a properly equipped 4Runner or FJ Cruiser running an Old Man Emu suspension system, the UCA0004 is the control arm we'd pair with the build.
