Dirt King Billet Upper Control Arms | Toyota 4Runner (2003-2024)

The Dirt King Billet Upper Control Arms are premium, precision-machined suspension arms engineered to improve handling, suspension articulation, and strength compared to stock control arms. Built from 6061-T6 aluminum, these billet arms correct suspension geometry for lifted applications — allowing up to about 3″ of lift when paired with aftermarket coilover shocks — and help maintain proper caster/camber settings as your vehicle travels through its range of motion.

Featuring a configurable inner pivot system and heavy-duty components, these arms are ideal for off-road, overland, and lifted street applications where enhanced durability and alignment performance matter.
