Show original supplier description
The CST CSS-C1-9 spindle lift system is engineered to provide a 3.5" to 5.5" lift for 2007-2015 Chevrolet Silverado 1500, GMC Sierra 1500, Suburban 1500, and Tahoe 2WD pickup trucks. This kit is constructed with fabricated 3.5" lift spindles, along with two sets of spacers (1" coil spring and 1" lower strut), extended steel braided front brake lines, and ball-joint taper sleeves to achieve the desired lift. All necessary installation hardware and instructions are included. CST highlights that this system is Made in the USA. A significant advantage of this CST lift kit is its compatibility with the GM Stabilitrak system found in most 2007 and newer GM fullsize pickup trucks. Unlike some other kits that can cause Stabilitrak warning indicators or ABS system interference, CST has redesigned their system to avoid these issues, ensuring a more seamless integration with your vehicle's electronics. To fully complete the lift, additional components such as a rear block lift, extended U-bolt kit, and rear shock absorbers are recommended but not included. For enhanced on- and off-road handling and suspension performance, an optional CST 0-2" lift coilover is available, which can contribute to achieving up to 5.5" of total lift. CST also recommends a 33" tall tire on 8" wide wheels with 5.00 inches of back spacing, noting that test fitting is mandatory for wheels with 5.50" back spacing to ensure clearance.
