Zone 6" Lift Kit 88-91 Chevy/GMC Blazer/Jimmy/Suburban 1/2 ton

Zone Offroad 6" suspension lift kit for 1988-91 1/2 ton Chevy/GM Blazer/Jimmy and Suburban's. Many hours of development and testing have finally produced a capable leaf spring that Zone Offroad is proud to introduce to our lineup. 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 washers are included for both the front rear. The rear of this system is lifted with a 4" lift block and add-a-leaf to achieve 5-6" of rear lift. 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 accessories 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.

Our prices are guaranteed low, our product knowledge and friendly service top shelf, and our never out of stock policy assures your Zone Offroad product will ship the same day if your order is placed before 1pm EST Monday -Friday.

    NOTICE: Zone OffRoad Products strongly recommends installation of products be done by a certified mechanic. If this does not occur be certain the person(s) installing the product read understand and follow all instructions and warnings pertaining to the application before installation.

    WARNING: Zone OffRoad Products does not recommend the use of a body lift in conjunction with a suspension lift 'Kit' or 'System'.

    PRODUCT SAFETY WARNING

    Installation of suspension lift kits or any other lifting kits or devices will raise the center of gravity. For this reason, Zone OffRoad Products urges that extreme caution be used when encountering driving conditions which may cause vehicle imbalance. Furthermore, the driver's field of vision and judgment will not be as good due to the height of the vehicle. Due to the installation of larger tires, the speedometer will read slower than the actual speed being traveled and more distance will be required to stop the vehicle. It is the owner's responsibility to caution and warn any potential driver of the vehicle about these driving and handling conditions.

    Zone OffRoad Products will not be held liable or responsible for damages or personal injuries resulting from the use of lifting devices and/or related products. The tires and rims should be changed to sufficiently increase the vehicle's total overall width and stability to help accommodate lifting devices.

    Zone OffRoad Products also recommends that the steering system on lifted vehicles be appropriately corrected to reduce steering stress and angles. Once completed, the vehicle should be inspected by a professional mechanic including such areas as the steering system, brake system, speedometer re calibration, and clearance, for tire and suspension travel and tightness of all installed products. Every Zone OffRoad Products suspension kit includes a "Driver Warning" decal and the literature explaining this information which should be read and understood completely before driving, and the decal should be placed in a position clearly visible by the driver and all occupants.

    NOTICE: Most states have some type of law limiting vehicle height. The amount of lift allowed, and how the lift can be achieved, varies greatly. Several states offer exemptions for farm and commercial registered vehicles. It is the vehicle owner's responsibility to check state and local laws to ensure that their vehicle will be in compliance.

    Zone OffRoad Products reserves the right to make changes in design, materials, specifications and product changes as deemed necessary without prior notice and without assuming and obligation to modify any product previously manufactured. Obligation or liabilities will not be assumed with respect to similar products.
