FOX 2.5 Elite Series Reservoir Shocks

The CST Performance Suspension Stage 3 System is a comprehensive leveling kit engineered for 2020 and newer GM 2500HD and 3500 SRW trucks. This kit includes CST fabricated upper control arms with high-angle ball joints, forged torsion keys, and FOX 2.5 Performance Elite Series adjustable reservoir shocks for both the front and rear. The system is designed to provide a level stance, increase suspension travel, and enhance ground and tire clearance, allowing for up to 35-inch tires. Key features of this system include superior control arm angles, OE-style rubber bushings for reduced road noise, and sealed/serviceable ball joints with a lifetime warranty on ball joints and UCA bushings. The FOX 2.5 Elite Series shocks are equipped with DSC (Dual Speed Compression) adjusters, offering 12 levels of high-speed and 10 levels of low-speed compression adjustment for customized ride and handling. CST recommends specific wheel and tire fitment for optimal performance with larger tires. For 17-inch wheels, a maximum backspacing of 4.79 inches is advised, while 18-inch or larger wheels should have a maximum backspacing of 5 inches. A recommended wheel width is 8 to 9 inches. Use of 35-inch tires may require trimming, depending on wheel width and offset. Installation time is reduced compared to other manufacturers' kits, and no CV spacers are needed. This system is compatible with 2020-2025 Chevrolet and GMC 2500HD, 3500 SRW, and 3500 Dually models, for both 2-Wheel Drive and 4-Wheel Drive configurations. It is important to note that this kit DOES NOT FIT AT4X or ZR2 models.
