General Motors revised the torsion bar suspension on this generation — which means generic keys from the previous platform won't index correctly and can create unsafe suspension geometry. The ReadyLIFT 66-30200 is engineered specifically for the updated 2020–2025 GM HD torsion bar system with new platform-specific indexing, delivering approximately 2\" of adjustable front lift and clearance for 35\" tires while maintaining the factory ride and handling.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe Result\u003c\/strong\u003e\u003cbr\u003eTwo industry-leading forged torsion keys with indexing designed specifically for the 2020–2025 GM HD platform deliver approximately 2\" of adjustable front lift — the exact amount varies by vehicle. Compatible with trucks equipped with either OE torsion key #84461807 or #84634344. The result is a level, aggressive stance that clears a 35x12.50 tire on a 20x9 +18 or 0-offset wheel with no trimming on most tread designs. Silverado and Sierra fender well opening sizes differ — minor trimming may be required on some tire styles on 20x9 0-offset or 325\/60R20 configurations.

Actual dimensions vary meaningfully by manufacturer — overall diameter, tread width, aspect ratio, and sidewall construction will differ. Every tire and wheel combination must be test fit prior to final installation. Upgrading to heavier 10-ply (Load Range E) all-terrain or mud-terrain tires will noticeably increase suspension stiffness and alter ride harshness compared to factory 6-ply (Load Range C) tires. Consult your local installer for application-specific guidance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation \u0026amp; Engineering Notes\u003c\/strong\u003e\u003cbr\u003eInstallation requires a torsion key unloading tool (ReadyLIFT 66-7822B or equivalent) — do not attempt installation without proper tooling. \u003cstrong\u003eCritical adjustment note:\u003c\/strong\u003e When setting the torsion key adjustment bolt, do not exceed 26\" measured from the wheel center to the fender edge. Exceeding this measurement creates a top-off condition where the suspension has little to no down travel — resulting in poor ride quality and premature component wear. A professional 4-wheel alignment is mandatory post-installation. Lifting your vehicle raises its center of gravity; exercise appropriate caution on- and off-road. All Advanced Driver Assistance Systems (ADAS) including GM Safety Alert Seat, Lane Keep Assist, and Forward Collision Alert must be checked and recalibrated after installation.\u003c\/p\u003e\u003cblockquote\u003e\n\u003cstrong\u003eEngineering Question:\u003c\/strong\u003e What is your factory torsion key part number — OE #84461807 or OE #84634344? And is your truck a Silverado or Sierra? Confirm your OE torsion key number and body style before ordering — fender well clearance varies between Silverado and Sierra, and AT4X\/ZR2 models are not compatible with this kit.\u003c\/blockquote\u003e","brand":"ReadyLIFT Suspension","offers":[{"title":"Default Title","offer_id":51631845245249,"sku":"66-30200","price":209.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/66-30200.jpg?v=1776290703","url":"https:\/\/obsidianforgedautosupply.com\/products\/readylift-2-0-forged-torsion-key-leveling-kit-gm-hd-2020-66-30200","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
