Review on Adjustable 1-3 Inch Heavy Duty Solid Leveling Lift Kits for 2011-19 Silverado GMC Sierra 2500HD 3500HD 4x4 - Dynofit Torsion Keys with Shock Extenders by Kevin Stephan

The keys are about a half inch different than the factory keys next door, honestly I could save a hundred bucks just using the factory keys and pocketing them. I increased the distance from the center of the wheel to the edge of the wing from 24 to 26 inches and it rode hard as a plank on the road. Also, the shock washers don't even fit over the shock studs. I think the best part is that the delivery was fast and everything was ready. I'd really like to spend the extra money and buy a branded kit, at least you get a legitimate upgrade key.
