Description
On a tall Toyota 4Runner, the difference between standard electric steps and the XL version is noticeable at the doorway. Kit 77155-01A drops lower to make climbing in easier.
The manufacturer confirms the application for 2010–2021 4Runners and specifies a no-drill installation. The paired aluminum boards retract after door closure, with vehicle-specific brackets and electronics included.
