This CST 4.5" to 5.5" Lift is designed to fit the updated 2014 and 2015 model year Chevrolet Silverado 1500 and GMC Sierra 1500. Please note this lift will ONLY fit 2wd models equipped with the CAST STEEL suspension. If your Silverado or Sierra has the Aluminum or Stamped Steel factory suspension this item will not fit. By design the CST Lift Spindles are NOT compatible on 4x4 models! This CST 4.5" to 5.5" Suspension Lift System is 100% compatible with the GM Stabilitrack system. This CST lift includes sufficient components to achieve up to 5.5" inches of front suspension lift. If you only want 3.5" inches of lift you can install the CST 3.5" Lift Spindles by themselves. If you prefer a 4.5" lift height you will install the CST 3.5" Lift Spindles and the provided 1" Lift Strut Spacer. If you want to lift your Silverado or Sierra 5.5" inches you will install the CST 3.5" Lift Spindles, 1" Lift Strut Spacer, and the 1" Lift Spring pre-load Spacer. With 5.5" inches of suspension lift and minor trimming up to a 35" tire can be run.

Printed Installation Instructions
Extended length rear shock absorbers are recommended. Rear shocks are NOT included with the CSK-C23-32K system but are available for purchase using the selection boxes located above this item description. As an optional upgrade CST offers their CSR-3500 0-2" lift coilover for the front of the Silverado and Sierra. The addition of the CST coilover to the CST 3.5" lift spindle will allow you to achieve up to 5.5" of lift without the use of the Strut Spacer or Pre-Load Spacers. The major benefit of the replacement front coilover is ease of ride height adjustment and the increase in on and off-road handling and suspension performance. Another performance option is the installation of the CST Pro-Joint Equipped Upper Control Arm. This Upper Arm provides additional suspension travel and strength and is an excellent upgrade for those looking to put together a Mid Travel system. The additional suspension travel makes a very noticeable difference in how the Silverado and Sierra react when driven more aggressively off-road and are a very worthwhile upgrade.
CST recommends the use of a 33" tall tire on 8" wide wheels. CST does admit that some 35" tires may fit at the 5.5" height range but your mileage may vary. Some wheels with 5.50" back space will work with this kit however test fitting is MANDATORY as not all wheels with 5.50" of back space will clear! If you want to run a larger tire we'd suggest performing a test fit before mounting up and installing all four tire/wheel combos. There's nothing worse than buying a tire and wheel combo that doesn't fit. If you need help selecting the correct tire and wheel package please let us know.
