In addition to replacing the OEM shocks, springs, struts, leafs and/or bushings with stronger, engineered-for-purpose heavy duty components, International Armored Group has also developed a progressive suspension system that helps evenly distribute the weight of the armored vehicle over many components to ensure the system never fails.


We work with the best suspension component manufacturers in the world to create custom  systems for all our armored vehicles that are designed and engineered in-house by our Engineering team.  These systems are custom made based on IAG’s specifications and are not available to other manufacturers.  The suspension engineering process takes into account IAG’s specific vehicle weights and distribution and are designed to work perfectly for our applications only.  This process ensures the driving capabilities and handling of the armored vehicle are optimized and also elevates the stress of dealing with separate suppliers for replacement and warranty purposes.

Additionally, IAG installs completely upgraded axle assemblies or reinforces the vehicle axles to cope with the added armor weight.  Advanced stress testing analysis software is used to examine every axle and make reinforcements as necessary in order to meet the vehicle’s expected payload and operating environment.

The vehicle brake system must be upgraded to cope with the added armor weight. Proper brakes are vital and can make the difference between life and death.  To correct for the new weight distribution and dynamic forces of the armored vehicle, specifically engineered heavy duty brake systems can be installed on every armored vehicle.  These systems can vary in performance depending on several factors such as rotor size, drilled vs. slotted rotors, calliper size, brake pad material composition and size, steel vs. regular brake lines, type of brake fluid used.  Depending on the final vehicle weight and area of operation, IAG can recommend and install different brake systems.



Wheels and tires are another vital component forming the complete armored vehicle package.  Both the wheels and tires need to be able to cope with the added weight of the armor plus passengers and payload.   If not chosen correctly, the rims can crack and tires puncture or even explode form the added weight.  Steel and aluminum rims are available depending on the necessary payload requirement, some have also been tested and certified to stop ballistic threats.


In addition to the rims, tires need to be upgraded as necessary to meet the required capacities.  When choosing the correct tire there are several factors that need to be considered.  Tread pattern – is important depending on the area of operation. PSI – the higher the PSI, the higher the payload capacity.  PLY – the number of layers that comprise the tire construction, the more the layers the stronger the tire.  Speed rating – due to the weight, armored vehicles’ speed is limited so the rating is not as important as the other factors.  Manufacture date – ensure the tires are manufactured in the same year as the vehicle. In general, we recommend selecting tires from well known manufacturers as they tend to be higher quality and perform better.
