Dial in your front ride height and keep the front torsion-bar suspension properly loaded with the Mevotech Supreme Torsion Bar Key MS43908. If you're replacing a worn key or setting torsion-bar preload, this front-suspension component holds the end of the front torsion bar and works with the adjuster bolt that sets torsion-bar preload and ride height. It fits many vehicles, among them the 1997-2003 Ford F-150, 1997-1999 Ford F-250 and 1997-2002 Ford Expedition. See the Buyer's Guide tab for the full list and engine-level detail.

  • OE-quality fit and performance: Mevotech rates it for OE-quality fit and performance on the listed applications.
  • Ride-height control: works with the adjuster bolt used to set front torsion-bar preload and ride height.
  • Front suspension: holds the end of the torsion bar so the adjuster can set its spring load.

Signs this key may need attention include a front end that won't hold its adjusted height, a seized or stripped adjuster bolt, or uneven front ride height. Sold individually; replacing both sides together is recommended. Have the front alignment and ride height set after installation.
