Kryptonite Stage 1 Leveling Kit Torsion Keys KR20STAGE1 Compatible with 2020-2024 Chevy Silverado/GMC Sierra 2500HD 3500HD

These keys will not give you enough clearance to fit 20x10 wheels with 33x12.5x20s. Maybe they would be fine with 20x9s, but anything larger than what I listed will require taking off the rain guard, and cutting the edge of the bumper, and rear fender to create enough clearance. My bumper is pretty wrecked, so I of course went with a saw-zawl to cut the bumper and a 12/lb sledge to bend the inner fender in. Highly do not recommend it. If you have a 2015-2017 Chevy/GMC you will want to get a 2-3” leveling kit, new bolts for your front upper shock mounts (stock ones are not long enough to install more than one shock extender which you should install per inch of leveling), and new shocks that are listed at 1.5”-2.5”. Crank the keys 50%-75% and you will clear 33x12.5x20 without cutting/modifying the bumper. And the keys have not affected ride quality. The tires eat up a lot more of the road so the increased torsion has not been noticed.
