Description
Upgrade your suspension performance and refresh your front suspension components with the SuperPro Front Upper Control Arm Kit, part number sprTRC491. Designed for compatible Lexus GX460, Toyota 4Runner, and Toyota FJ Cruiser applications, this kit combines complete upper control arm assemblies with upgraded ball joints and pre-installed SuperPro polyurethane bushings.
While replacing suspension bushings can improve suspension performance, the condition of the original control arms and related components can limit the results. The SuperPro TRC491 addresses this by replacing the complete upper control arm assemblies rather than requiring bushings to be installed into existing arms. Each assembly arrives pre-assembled with SuperPro bushings and upgraded ball joints, helping save installation time while refreshing key suspension components.
Constructed from steel and designed in a standard, non-adjustable configuration, this premium performance suspension kit is intended to provide a factory-style fit while supporting improved durability, handling, and driving comfort.
