Total Chaos, 4130 Chromoly Uniball Upper Control Arms, for Toyota 4Runner, Toyota Tacoma

Total Chaos 4130 Chromoly Uniball Upper Control Arms

Upgrade your next-generation Toyota’s front suspension with the Total Chaos 4130 Chromoly Upper Control Arms. Specifically engineered for the Land Cruiser 250 (Prado), Lexus GX550, 2024+ Tacoma, and 2025+ 4Runner, these arms are designed to maximize performance whether you're running a stock setup or a high-performance lift. While Toyota’s new suspension geometry has reduced the need for caster correction, these UCAs are essential for off-roaders seeking increased durability and wheel travel. When paired with extended-length coilovers, these arms allow for up to 1 inch of additional wheel droop travel, ensuring your tires stay in contact with the ground on technical terrain.

Total Chaos replaces the weak factory ball joint with a massive 1" heat-treated stainless steel uniball, significantly increasing component strength and allowing for maximum articulation. The arms are handcrafted in the USA from 4130 Chromoly tubing and feature a 3-stage powder coat finish for long-lasting protection against the elements. To sharpen steering response, the kit utilizes urethane bushings that reduce deflection compared to soft factory rubber, while integrated Zerk fittings allow for easy maintenance without the need for disassembly.
