Total Chaos, Heim Joint Upper Control Arms, for Toyota FJ Cruiser & 4Runner

Total Chaos Heim Joint Upper Control Arms

Lifting your vehicle is the first step toward off-road performance, but a lift alone can create alignment limitations. Total Chaos Upper Control Arms (UCAs) are engineered to solve these issues by correcting the caster angle lost during the lifting process. Built from 100% bolt-on 4130 chromoly tubing, these arms are designed to add 3 degrees of caster, significantly improving straight-line tracking, high-speed stability, and cornering performance. Hand-crafted in the U.S.A., they provide the durability and adjustability needed for serious off-road builds.

These arms feature 1" I.D. uniballs with heat-treated stainless-steel components and a military-grade PTFE liner to reduce noise and maintenance. The inclusion of 3/4" chromoly heim joints at the pivots allows for maximum tuning of both caster and camber. Whether you are running a standard 1.5"-3" lift or a 4" or higher drop bracket kit, these UCAs maintain factory alignment specs and are the only arms on the market designed to clear a 3.0" diameter coilover shock without contact.

Features

• Fully Adjustable Heim Pivots: 3/4" chromoly heim joints allow for precise fine-tuning of caster and camber beyond factory limits.
