Upgrade your suspension with the Dirt King Billet Upper Control Arms for Toyota 4Runner (2025–2026). Precision-machined from 6061 aluminum, these premium upper control arms combine exceptional strength, improved suspension geometry, and a refined billet appearance that stands out under the hood of any 6th Gen 4Runner build.
Designed to correct factory suspension limitations, Dirt King billet UCAs improve caster settings and pivot angles to restore proper geometry on lifted vehicles. This results in better handling, increased articulation, and improved suspension travel when paired with Dirt King shocks or other aftermarket coilovers.
These upper control arms feature an adjustable inner pivot system available in two configurations to match your driving style. Choose the maintenance-free Probearing SilentSpin™ bushings for quiet, smooth operation and daily driving comfort, or opt for the ¾" chromoly rod ends for a firmer, performance-focused setup ideal for aggressive off-road use.
Both configurations include heavy-duty Probearing ball joints, engineered for durability in harsh environments while maintaining smooth steering performance. Built for strength, adjustability, and long-term reliability, these billet control arms are a premium suspension upgrade for any lifted 4Runner.
