CST Performance Suspension 6-8" lift kit for 1999-2006 and 2007 Classic Body Style 4wd Chevrolet Silverado and GMC Sierra trucks. As usual, CST spared no expense in designing and building the best kit available for the GM 1/2 tom K1500 series Silverado and Sierra. CST developed this 6-8" lift kit without cutting any corners. This CST kit is able to retain the factory track width and even works with factory wheels. Here is why... Most kits use a replacement steering knuckle that increases the track width and requires the use of non-factory wheels. The knuckle kits also limit the owner to a preset lift height. In other words, using aftermarket steering knuckles on a 4x4 GM IFS truck is the cheap and easy way out to design a kit. If you want cheap and easy look at another kit. This CST 6" to 8" suspension lift does NOT use replacement steering knuckles and is without a doubt the finest suspension system available for 1999, 2000, 2001, 2002, 2003, 2004, 2005, and 2006 full-size 4x4 K1500 trucks. Its been the best 6-8" suspension kit on the market for almost six years now and no other manufacturer has even come close to matching CSTs quality or performance. This CST kit even won a 2007 Magazine Suspension Lift Shootout!!! This is the best kit we offer for the Silverado and Sierra, period!

The CST CSS-C3-2 6" to 8" lift kit is an extensive suspension system, an absolute requirement since the GM IFS trucks OE suspension is a complex design which incorporates the 4WD driveline. Basically, the CST system drops the entire front suspension and driveline down 6 inches through the use of a special 1-piece welded sub-frame. The upper arms are dropped the same amount as the lower arms. This helps retain the factory steering geometry and ensures great OEM like handling. Steel spacers, brackets, and struts lower and support the front differential, custom mounts relocate the torsion bars, a fabricated dropped center link provides precise steering control and response, anti-sway bar spacers allow for stock sway bar retention. A rear lift block and u-bolt kit is also included as is all of the required installation fasteners. Heavy Duty and Bulletproof are words that drivers use when they comment on this kit. If you're looking for a lift that behaves as well on the road as it does off, the CST Silverado and Sierra 6-8" kit is for you.

Please note that AutoTrac equipped vehicles will require an aftermarket front driveshaft! PerformanceLifts.com offers this replacement driveshaft for $399.00, a considerable savings over other companies that sell their driveshafts for hundreds more! PerformanceLifts.com is also one of the only dealers that offers the specially built shock absorbers that the Silverado and Sierra 1500 4wd trucks require when running the CST 6-8" lift kit. And speaking of options... CST also offers a front and rear dual shock kit for use with this 6-8" suspension lift that allows the use of two standard or two Fox Racing 2.0 series reservoir shock absorbers at each wheel!
