CST 2001 - 2010 Silverado and Sierra 2500HD 9-11" Lift - Stage 1 # CSK-G9-1

CST Performance Suspension 9-11" Kit # CSK-G9-1. This suspension lift system is designed to fit 2001 - 2010 model year 1500HD, 2500HD and 3500 SRW Heavy Duty Chevrolet Silverado and GMC Sierra Trucks. If your are looking for a suspension lift that is designed to outlast and outperform every other kit on the market, this is the one. This CST Performance Suspension kit is listed as a 9-11" lift kit because with the addition of torsion lift keys you can adjust the height up to the full 11" of lift. Without any torsion bar modification you get a true 9" inches of suspension lift!

If your 4wd 2500HD or 3500 SRW is equipped with an Allison transmission you are not required to run an aftermarket front driveshaft but it is recommended for customers that operate their truck in 4wd at any speed over 15mph. Without the replacement front driveshaft you will experience a front driveline vibration. Our recommendation is install the kit, put the truck in 4wd and test drive it. If you notice a vibration in 4wd you need the replacement front drive shaft... if you don't notice any vibration at the speeds you drive in 4x4 the drive shaft isn't required.

CST Performance Suspension quality and craftsmanship are evident in this product. As always, this CST kit is the finest suspension lift available for the Chevrolet and GMC HD trucks - period! CST Performance Suspension is an American Company employing American craftsman! The CSK-G9-1 kit is designed to provide 9" inches of lift using a one-piece welded subframe. This is good for a few reasons.... It means front axle shaft joint angles remain well within factory tolerances and this reduces the likelihood of premature CV joint wear or failure. It also keeps the steering geometry in check and helps retain the factory geometry. The GM engineers spent countless hours designing the steering system on your truck, and for good reason. CST understands this and tries very hard to maintain factory geometry. This ensures your truck will drive and handle as the engineers designed it to. In other words, when you turn the steering wheel the truck will actually turn. A few "other" kits on the market handle like junk, just ask their owners! The CST 9-11" kit does NOT require a new steering knuckle or CV spacer like other kits and this also means reduced CV wear and differential damage. Even better, the CST kit does not drastically widen the front of the vehicle like other kits do. A narrower front track width means less wear and tear on steering and suspension related components and the ability to run larger tire and wheel combos! It also opens up a wider range of possible wheel choices. The ability to use a wheel with more backspace means more choices are available to you. The CST 9-11" 2500HD and 3500 SRW kit does require some cutting but only on the back side of the driver side lower control arm mount. That's it! The CST kit includes the now famous CST 1-piece welded subframe along with strut bar supports that increase strength and really lock the suspension into the frame. Supported upper control arm drop mounts, a Heim joint (rod ends) equipped steering linkage, and the awesome CST gloss black powder coat make this kit look as good as it performs.

Shock Absorber Information:
Please note - Shocks are not included with this kit. CST does include an upper shock mount that converts the factory STEM style mount to a loop. CST also offers their popular CST Dual Front Shock Mounting Kit as an optional purchase. To put together a complete CST Dual Shock Kit requires the purchase of the CST Dual Shock Hoop and the the CST Dual Shock Upper Control Arm kit. Shock absorbers are not included with the CST Dual Shock system but are available for purchase below.

Rear Lift Information:
CST does not include any rear lift with the CST 9-11" Foundation Kit. PerformanceLifts.com recommends installing a pair of Deaver Spring Co or Atlas rear spring packs to lift the rear of your truck. Thin leaf progressive rate leaf springs will provide a better ride than the factory pack due to the increase in arch and the "thin leaf" design. The leaf pack you choose will depend on what lift height you plan to run your CST 9-11" lift at. If you want to run the kit at 9" of lift and want a level stance we recommend the 6" lift packs + a 1" lift block. If you want to run the CST lift at 10" to 11" of lift we recommend 8" lift packs. If you adjust your CST lift to provide the full 11" of lift from the kit you may want to add a 1" block kit in addition to the 8" Lift Rear Springs to level the truck front to back. This becomes personal preference so what looks great to one person might be unacceptable to another.
