CST 2011 - 2019 GM 2500HD 4" Lift Spindle Kit # CSK-C1-10-1

CST Performance Suspension GM 2500HD 4" Lift Spindle Kit # CSK-C1-10-1 is designed to fit the 2011-2019 Chevrolet Silverado and GMC 2500HD Rear Wheel Drive trucks only - DOES NOT FIT 4x4 MODELS! The White Crew Cab truck displayed in the product images is running the CST 4" Lift Spindles, a mild torsion bar adjustment, and has sufficient room to clear 35" tires!

The rear of your Silverado or Sierra 2500HD / 3500 truck is lifted using a CST Fabricated 2" Rear Lift Block and Extended Length U-bolt Kit. We offer a number of different rear block heights that will allow you to achieve the exact stance you want. With a 4" Lift up front a 2" rear block kit will level most trucks. If you plan on running this 4" Lift Spindle in addition to a 2" Torsion Bar Adjustment you may need a taller rear block to achieve a level stance. Optional height CST Lift Block and U-Bolt kits can be purchased using the drop down selection boxes located near the "Add to Cart button".

Tire & Wheel Fitment Information:
With the addition of this 4" Lift Spindle a 33" tire can be used without any additional modifications. With a 2" lift Torsion Bar Adjustment this 4" Lift Spindle will combine to provide 6" inches of lift height over stock. With 6" of lift a 35" tire mounted on an 8" or 9" wide wheel will clear. This CST 4" Lift Spindle has been test fit and is compatible with the 2015 and newer factory 20" diameter wheels. When running aftermarket wheels CST recommends a maximum wheel backspace of 4.75" inches and a maximum wheel width of 9" inches. You have the option to 10" or wider wheels but the wider wheels are more likely to cause rubbing issues when running larger tires.
