MADE IN U.S.A. - READYLIFT® is the most cost-effective and time-efficient way to lift your 2007-2015 GMC Sierra 1500 6-lug new body style pickup ride height by lifting the front 2.25”. READYLIFT® suspension products do not require any permanent modification to factory parts and never compresses the factory springs or require cutting the strut studs. READYLIFT® leveling kit systems will not affect your factory OEM ride quality or comfort level. The 66-3085 kit includes (2) aluminum SST Strut Extensions and (2) aluminum SST Lower Strut Mount Spacers along with all neccessary hardware. These are CNC-machined 6061-T6 solid billet aluminum construction, not spot welded low grade stamped steel often found with cheaper quality kits.

This kit will work on new 2015 GM 1500 Trucks!

This kit is not for use on 2007-2013 Z71 or 2014-UP Z71 Off Road trucks.


Note: Using 66-3085 on 2007-2013 Z71 - front end will sit higher than the rear. 2007-2013 Z71 want to use 66-3080 for level stance.


Note: Using 66-3085 on 2014-2015 Z71 Off Road or Z71 trucks with approximately 1.0" of rake from front to rear will result in front end sitting higher than the rear. If your 2014-UP truck has 2.0"-3.0" of front to rear rake - use 66-3085. If 1.0" of rake - use 66-3080 for a level stance.

    Just wanted to leave a review on this product. I purchased this 66-3085 leveling kit and couldn't be happier. It lifted my truck as advertised and yes, my truck does still ride like stock but looks so much better! (Posted on 12/9/13)

    Thanks Readylift, this kit was easy to install even for a novice like me. Lifted my truck perfect for the 33 inch tires I bought. I like that this kit is made from aluminum and not cheap plastic like some other kits I was looking at. Thanks again. (Posted on 12/9/13)
