BUILT FOR THE NEW GENERATION OF TOYOTA 4X4s
Old Man Emu Upper Control Arms | Tacoma, Land Cruiser 250 & Lexus GX550
A suspension lift changes more than ride height. It changes suspension geometry.
The latest Toyota Tacoma, Land Cruiser 250 and Lexus GX550 are exceptionally capable platforms, but lifting an independent front suspension vehicle changes the relationship between the chassis, steering knuckle and factory upper control arm. Caster and camber adjustment can be pushed outside the range Toyota originally designed into the vehicle.
The Old Man Emu UCA0021 Upper Control Arm Kit is engineered specifically for these new-generation Toyota and Lexus platforms, helping restore usable suspension geometry 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
Factory upper control arms are engineered around factory suspension height. Raise the front suspension and the operating angle of the upper control arm changes with it, affecting alignment geometry and the way the suspension moves through its travel.
Old Man Emu engineered the UCA0021 specifically for lifted applications, helping restore usable caster and camber adjustment while providing the additional clearance and suspension movement required by a properly upgraded suspension system.
The objective isn't simply to make the vehicle sit higher. It's to build a suspension system in which the shocks, springs, control arms and alignment geometry continue to work together.
Engineered as Part of the Suspension System
Corrected Suspension Geometry
Designed to help restore usable caster and camber adjustment after lifting the vehicle, allowing proper alignment of the upgraded suspension.
Heavy-Duty Construction
Tubular steel control arms incorporate forged ball joint housings and eyelets to 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 a sealing cap for durability in demanding road, trail and Canadian winter conditions.
Improved Clearance & Travel
The upgraded control-arm design helps provide the clearance and freedom of movement required by compatible lifted suspension systems.
Designed for OME Suspension
Engineered to complement Old Man Emu suspension systems, including compatible MT64 and BP-51 applications, rather than treating the control arm as an isolated component.
THE REAL-WORLD DIFFERENCE
Build the Suspension to Drive Properly, Not Just Sit Higher
A Tacoma, Land Cruiser or GX550 built for adventure still spends plenty of time on pavement. Steering response, alignment, tyre wear and predictable handling matter on the highway just as much as suspension travel and clearance matter once the pavement ends.
That's why upper control arms make sense as part of a properly engineered suspension build. The objective isn't simply more clearance. It's getting the suspension geometry back where it belongs so the upgraded system can perform the way it was intended.

VEHICLE FITMENT
Toyota & Lexus Applications
UCA0021 is designed for select current-generation Toyota and Lexus independent front suspension platforms, including:
- Toyota Tacoma: 2024+ fourth-generation Tacoma
- Toyota Land Cruiser: 250 Series
- Lexus GX: GX550
Have a 2005-2023 Tacoma? Second and third-generation Tacoma models use the Old Man Emu UCA0005 upper control arm. UCA0021 is designed for the newer vehicle platform.
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.
The new Tacoma, Land Cruiser and GX550 are excellent platforms for a proper adventure build, and it's easy to focus the suspension budget entirely on shocks and springs. But once an independent front suspension vehicle is lifted, geometry becomes part of the equation.
That's particularly important on vehicles being built for real-world use. These aren't dedicated competition trucks. They're vehicles that may spend hours on the highway before reaching the trail, carrying passengers, camping equipment and everything else that comes with an adventure build.
For a properly equipped new-generation Tacoma, Land Cruiser 250 or GX550 running a compatible Old Man Emu suspension system, the UCA0021 is the control arm we'd pair with the build.
