6.5" Strut Spacer Suspension System | 2007-13 Chevrolet 1500 Silverado & GMC 1500 Sierra 4WD pickups.

Zone Offroad now offers a strut spacer alternative to our popular 07-13 6.5" replacement strut system. This new kit includes many of the same features as the current replacement strut kit but is geared more toward those that don't need the added performance of the replacement strut. The new strut spacer system still utilized the tried-and-true combination of ductile cast iron, precision machine steering knuckles along with 1-piece heavy duty crossmembers to help make the lift possible. 

A differential skid plate is included along with all the necessary differential and sway bar relocation brackets. The heavy duty, fully welded strut spacers bolt directly to the top of the factory strut and do not require disassembly of the strut. 

In the back, Zone Offroad only uses solid cast rear lift blocks as opposed to fabricated blocks and limits the height to 5". If you need additional rear height, Zone offers a preferred add-a-leaf to fight spring wrap and yield additional height. Nitro rear shock option available.

FMVSS No.126 compliant

The NHTSA's Federal Motor Vehicle Safety Standard (FMVSS) No.126 requires all new passenger vehicles to include Electronic Stability Control (ESC) systems that meet certain standards that can be tested through a comprehensive series of evasive maneuvers. Aftermarket products must meet these standards as well.

Zone Offroad Products is leading the industry by independently testing all suspension kits to verify the kits are fully compliant with the stability control system requirements set by Federal Motor Vehicle Safety Standard (FMVSS) No. 126.

Products that wear out or fail due to the use of larger wheels or tires are not covered under this warranty by Zone OffRoad Products. Products installed on a vehicle used in any form of competition or racing are not covered by this warranty. The warranty on commercial application vehicles shall extend only 1 year. No warranty is available on items subject to normal wear and replacement.

Shock oil seals are subject to wear over time, and use. Therefore, are not covered under warranty. However leaking shock seals less than one year from date of purchase, free from contamination, damage, or abnormal seal wear due to misuse can be considered for Warranty.

This Limited Lifetime Warranty does not apply to products characterized by one or more of the following:

  • Products that have been subject to abuse, neglect, accident, fire, improper installation or adjustment, and corrosion.
  • Products that have been modified or altered outside of or beyond Zone OffRoad Products
  • Products used in application other than those recommended in the current Zone OffRoad Products catalog or web site or in the instructions accompanying the Zone OffRoad Products product.
  • Products that are used for competition or racing activities. This Limited Lifetime Warranty does not include polyurethane components, product finish and conditions caused by normal wear and use.

In a situation where a Zone OffRoad Products product is found to contain a defect in material or workmanship within the stated warranty period (unless caused by one or more of the above stated conditions), Zone OffRoad Products, at its option, will either replace the product or repair the product. To make a claim under this Limited Lifetime Warranty, purchaser must:

  • Contact the original place of purchase for further instruction. A Return Merchandise Authorization (RMA) number is required for warranty claims. The RMA number must be displayed on the outside of the product's package.
  • Include the original purchase receipt (or copy) indicating the place of purchase, date of purchase, and amount paid,
  • Return the product, freight prepaid, as instructed by the original place of purchase. Zone Offroadand Overland Protocol are not responsible for freight charges.

Freight charges, installation cost, labor cost, damage to related components, cost incurred due to down time of vehicle, normal wear and tear, lost profits and incidental or consequential damages are not covered under this lifetime warranty.

This Limited Lifetime Warranty gives you specific legal rights, and you may also have other rights, which may vary from state to state. There are no warranties expressed or implied (including any implied warranties of merchantability and fitness), which extend beyond this Limited Lifetime Warranty described herein.

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'.


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.
