4.5" Suspension System

The 4.5'' system for the 2WD 1/2-ton GM trucks mimics the geometry of the tried and true, FMVSS No.126 compliant 4WD lift systems. The kits include a pair of fully boxed heavy duty crossmembers and robust ductile iron steering knuckles engineered to work with the redesigned steering rack. This coupled with the crossmember braces creates an incredibly strong front subframe designed to correct suspension geometry while increasing ground clearance. To retain factory ride quality a pair of bolt-on strut spacers are used to provide lift. These install easily without the need to disassemble the factory strut. Also included in the kit are brake line brackets, sway bar relocation, rear 4' blocks, u-bolts, your choice of hydro or nitro rear shocks and all the necessary hardware to complete the install.

Optional accessories for this lift kit include Zone front skid plate available separately. As with all Zone kits, this 4.5'' system is backed by Zone's limited lifetime warranty, FMVSS No.126 ESC system compliance, and 5-year 60,000-mile drivetrain protection through 560plus.com.

  • FMVSS No.126 (ESC system test) Compliant

  • Properly corrects suspension geometry and allows for larger wheels/tires
  • Heavy duty boxed one piece crossmembers that maintain a clean look
  • Crossmember support struts included for maximum subframe strength
  • Weld-in control arm pocket plate included
  • Rear solid cast iron blocks

Important Notes

  • *IMPORTANT*: GM is producing several knuckle/control arm configurations in 2014-2017 models trucks. Cast Steel control arm equipped models will require the "Cast Steel Control Arm" kit (#C35). Stamped Steel and Aluminum control arm equipped models will require the "Aluminum Control Arm" kit (#C36). Be sure to verify which factory control arms your truck has before ordering your kit by referecing our help image below (click image for larger view):

  • To reduce trimming required for tire fitment, a 20" wheel w/5.75" backspacing is recommended
  • Factory 17" and 18" wheels cannot be reinstalled due to tie rod end interference

    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. Installation instructions are also available prior to your purchase.

    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.
