The factory keys are calibrated to produce a slight nose-down rake — intentional from Ford for aerodynamics and load geometry. Zone Offroad's replacement keys are machined at a different index position that raises the front approximately 2 inches, leveling the nose-down factory rake and allowing a squared, level stance. No cutting, drilling, or welding is required — the factory torsion keys are removed and the Zone keys are installed in their place.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eResonance frequency testing:\u003c\/strong\u003e Zone confirms all torsion key castings are resonance frequency tested to ensure structural integrity before shipment.

Many 1997–2003 F-150 4WD trucks did not include them from the factory. After raising the front with new torsion keys, the alignment angles will shift — without alignment cams, a professional alignment shop cannot correct those angles. Zone Offroad explicitly flags this for this platform. Confirm your truck's alignment cam status before installation and source them if absent.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWill this also raise the rear of my truck?\u003c\/strong\u003e\u003cbr\u003eNo — this is a front-only torsion key leveling kit. It raises the front approximately 2 inches to eliminate the factory nose-down rake.
