General Motors introduces the new 2011 2500HD/3500HD platform and ReadyLift responds by developing the strongest, safest leveling key system on the market. The ReadyLift 66-3011 2011-Up Silverado/Sierra HD Forged Leveling Key kit uses ReadyLifts time tested engineering technology to bring to market exactly what ReadyLift customers demand.

The new GM 2500 HD suspension required developing an entirely new leveling kit system, a system that includes Forged Torsion Leveling Keys engineered to give the 2011-Up GM 2500/3500HD 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 percent 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 the 2011-2012 HD 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 our new forged torsion key. You won't see other companies doing the research that ReadyLift does. Most of the 2011-2012 on the market use previous model design elements which are not designed for use on a much bigger and heavier 2011-2012 2500/3500 HD truck!

The NEW 66-3011 Leveling Kit includes two new Forged Torsion Keys, four front shock extensions which allows the customer 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. From light duty to heavy duty Trucks or SUV's, ReadyLift is the smart way to lift and your truck.

Note: 2011-2012 GM HD trucks require the use of ReadyLift 66-7816A Universal Torsion Key Unloading Tool.
