ReadyLIFT 66-3011 2.25" Torsion Key Leveling Kit 11-19 GM 2500HD / 3500

The strongest, easiest way to level out your Chevrolet or GMC Heavy Duty.The new heavy duty GM's suspension required developing an entirely new leveling kit system, a system that includes Forged Torsion Leveling Keys engineered to give the 2011-UP GM 2500/3500 HD trucks a level stance while maintaining the factory ride. Even more important is that ReadyLIFT is the only company to offer a forged torsion key that is both 25% stronger than OEM key and designed using the same features as the OEM key. Some important areas such as the wider keyway shoulder have been maintained with the ReadyLIFT leveling key. It is important to understand that starting in 2011, these trucks have an entirely new suspension design that is twice as large as the previous model. The factory design specific structural features in the 2011 key requirements and ReadyLIFT chose to maximize those same features in their new forged torsion key. You won't see other companies doing the research that ReadyLIFT does. Most of the comparable kits on the market use previous model design elements which are not designed for use on a much bigger and heavier 2011+ 2500/3500 HD truck! This kit includes two new Forged Torsion Keys, four front shock extensions which allows you to retain the use of the stock shocks, and four new shock mounting nuts for a precise and professional installation. Each key and shock spacer is protected with a durable e-coated finish to prevent rusting commonly found on other keys. Allows for the installation of larger aftermarket plus-size tires and wheels. READYLIFT offers a Lifetime Warranty on all of its products. IMPORTANT NOTE: Requires the use of ReadyLIFT Universal Torsion Key Unloading Tool for proper installation.
