Forged steel keys replace the factory torsion bar keys and index the torsion bar at a higher preload position, raising the front of the truck to correct factory rake and level the stance. Actual lift achieved varies based on torsion bar condition and factory preload — up to 2\" is typical on trucks with unworn torsion bars. Corrosion-resistant finish. Direct bolt-on installation. Front-end alignment is mandatory after installation.\u003c\/p\u003e\n\n\u003ch2\u003eVerified Fitment (OFAS Standard)\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChevy Silverado 1500 6-Lug (Front):\u003c\/strong\u003e 1999–2006 — torsion bar front suspension\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGMC Sierra 1500 6-Lug (Front):\u003c\/strong\u003e 1999–2006 — torsion bar front suspension\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDoes NOT fit:\u003c\/strong\u003e 2007 or newer Silverado\/Sierra 1500 (switched to coil spring front suspension — no torsion bar).

Do not index torsion bars beyond their rated preload range — over-cranking can cause torsion bar fatigue and failure.
