Skyjacker 2.5"SYS 88-91 1/2T SUB/52"

Extra Clearance for Half Ton Suburban Duty

The Skyjacker C125AKSS8-N delivers a complete 2.5 inch suspension lift system built for 1988 to 1991 Chevrolet and GMC half ton Suburban models equipped with 52 inch rear leaf springs. This system raises ride height for larger tire clearance while Skyjacker engineers the geometry to keep the factory ride quality and steering response intact. The kit pairs front and rear lift components sized for the half ton Suburban chassis with Nitro gas charged shock absorbers tuned to the 2.5 inch lift height. Because these Suburbans often carry family or work loads, Skyjacker designed the C125AKSS8-N to maintain stable handling under real world use, not just at showroom ride height. Installation uses the factory mounting points along with the included hardware, so no permanent cutting or drilling is required.
