Upgrade the front suspension on your 6th Gen 4Runner with the Dirt King 4130 Upper Control Arms for Toyota 4Runner (2025–2026). Designed specifically for lifted applications, these heavy-duty UCAs correct suspension geometry, improve articulation, and eliminate common issues found in factory control arms.

Built from 4130 chromoly tubing and engineered for strength, these upper control arms feature maintenance-free SilentSpin™ bushings and Probearing Pro 4 ball joints for smooth operation and long-term durability. Whether your 4Runner is a daily driver, weekend overland rig, or dedicated off-road build, Dirt King UCAs provide the strength and reliability needed for demanding terrain.

Designed to maintain proper alignment with 0–3 inches of lift, these arms also increase front suspension performance by adding approximately 1 inch of additional down travel compared to factory arms. Pair them with aftermarket coilovers such as King, Fox, Icon, Dirt King, and other performance suspension systems for maximum capability both on and off the trail.
