4" Lift Kit, 1/2 Ton, 88-91 Blazer & Suburban. Zone Offroad 4" suspension lift kit for 1988-91 Chevy Blazer, GMC Jimmy, and Chevy/GMC Suburban. Many hours of development and testing have finally produced a capable leaf spring that Zone Offroad is proud to introduce to the linup. These springs are a 5 leaf pack with anti-friction pads and center leaf spacer plates between each leaf. This design significantly decreases leaf pack internal friction for a smooth and consistent spring rate.
This system comes complete with a 4" steering arm to correct the drag link angle. Zone Offroad also addresses the brake lines by providing front and rear brake line relocation brackets. Front and rear yellow zinc plated u-bolts with high nuts and washer are included. The rear of this system is lifted with a 4" lift block. If your truck came with a front sway bar, Zone Offroad has you covered with a unique shackle sway bar link design listed in the kit options that will fit lifts from 2-6". Choose Zone Offroad for this affordable yet high quality system for your 88-91 Jimmy, Blazer, or Suburban and have no regrets!

*The front driveshaft may need to be clearanced at the double cardan joint to prevent binding at full droop on some models.
*The front exhaust cross-over pipe may need to be modified to clear the front driveshaft on some models.
*Some models came equipped from the factory with a dual front shock setup, with the second set of shocks commonly being referred to as "Auxiliary" shocks.
