Description
Toyota Mid-Travel 1″ Uniball Upper Control Arms
The Solo Motorsports Toyota Mid-Travel Upper Control Arms are designed to improve suspension geometry, increase wheel travel, and replace the factory upper ball joint with a heavy-duty 1″ uniball.
Lifting a Toyota approximately 2–3″ with aftermarket coilovers changes the factory suspension geometry and can reduce positive caster. This can contribute to wandering and reduced straight-line stability. We build additional positive caster into our upper control arm geometry to help bring the alignment back where it belongs and improve how the truck drives after lifting it.
Why We Use a 1″ Uniball
The factory upper ball joint becomes a limiting point as suspension travel increases. Our UCA replaces it with a 1″ FK uniball and high-misalignment spacers, allowing greater angular movement for off-road suspension use.
Combined with the proper aftermarket coilover, the Solo UCA can provide approximately 1″ of additional wheel travel over stock.
A CNC-machined spindle adapter converts the factory upper ball joint mounting location to accept the 1″ uniball while retaining the factory spindle.
Built for Street and Off-Road Use
Each UCA is fabricated from high-strength DOM tubing and uses polyurethane frame-side bushings with heavy-duty inner sleeves. This provides a strong, serviceable pivot while maintaining a straightforward bolt-on installation.
The arms work with factory coilovers, lift spacers, and aftermarket coilovers, making them a versatile upgrade whether you’re correcting the geometry of a lifted daily driver or building a mid-travel off-road suspension system.
For vehicles that see aggressive off-road use, we highly recommend pairing these arms with our UCA Double-Shear Reinforcement Kit to strengthen the factory coil bucket and upper control arm mounting point.
Made in the USA.

Important Notes
These upper control arms are designed to work with both factory and aftermarket Toyota spindles depending on the application and required adapter configuration.
For trucks that see aggressive off-road use or long-travel suspension use, the Solo Motorsports UCA Double-Shear Reinforcement Kit is highly recommended.
A professional alignment should be performed after installation.
