Fitment and setup
Listed application: 2010–2023 Toyota 4Runner. Confirm the exact vehicle configuration and installed suspension components before purchase. This listing does not establish compatibility with every lift height or aftermarket suspension combination.
The arms are designed to help correct caster alignment on compatible lifted applications; they do not independently raise the vehicle. Have the suspension installed and aligned to the appropriate specifications, and follow the supplied installation and lubrication instructions.
