Skyjacker 4"SR SYS 88-91 BALZER/JIMMY

Serious Height for Serious Tires on the Square Body Chassis

The Skyjacker C140AKS8-N is a complete 4 inch suspension lift system engineered for 1988 to 1991 Chevrolet Blazer and GMC Jimmy four wheel drive models. This system delivers the extra clearance needed to run 33 to 35 inch tires while Skyjacker tunes the geometry to control body roll and maintain predictable steering response at the taller ride height. The kit includes front and rear lift components matched to a 4 inch application along with Nitro shock absorbers valved for the increased suspension travel. Skyjacker built this system for square body Blazer and Jimmy owners who want to move beyond a mild lift and into a setup capable of handling larger wheels, tires and off road articulation. Installation uses factory mounting locations with the included hardware for a straightforward bolt on process.

About Skyjacker

Skyjacker Suspensions has engineered lift kits for trucks and SUVs for decades, matching lift components and shocks to specific ride heights so drivers get predictable handling rather than a generic spacer lift. The C140AKS8-N brings that engineering to the classic square body Blazer and Jimmy platform at a full 4 inches of lift.
