Optimized Suspension Performance
Our Adjustable Front Control Arm Set is a critical upgrade for restoring caster alignment, reducing wandering at highway speeds, and improving steering stability. Paired together, upper and lower control arms provide full axle recentering, reducing suspension stress and premature tire wear. For trucks used in towing and hauling, correcting caster angles is essential for maintaining stability and control under heavy loads.
Two-Stage Powder Coating
To ensure maximum durability and corrosion resistance, all control arms undergo a two-stage powder coating process. The first stage includes a zinc primer base coat, offering superior rust prevention and long-term protection. The second stage applies a durable top coat, available in 10 color options, allowing you to customize your suspension components while ensuring a long-lasting, high-quality finish.
Made in the USA
Proudly manufactured in Orem, UT, our control arms are built with American-sourced materials, ensuring strict quality control and superior reliability. Supporting American manufacturing means investing in premium craftsmanship and long-lasting performance for both work and off-road applications.
Optional Hardware Upgrade
These control arms install using factory hardware, but for rusted or stubborn bolts, we offer Grade 8 hardware kits, available separately, for a hassle-free installation.

Upgrading to the Adjustable Front Control Arm Set means investing in better alignment, enhanced stability, and long-term durability.
