4x4 to 4x6 Extender on StrikeRazor SxS LTV

RP Advanced Mobile Systems now offers a modular 4x4 to 4x6 vehicle wheeled extender kit system specifically designed and intended for increasing the ATV/SxS LTV/UTV mobile payload capability of the SOF warfighter without the need of a trailer.

This system enhances the mission of StrikeRazor by increasing payload and warfighter capability while maintaining denied access maneuverability through the installation of a wheeled fully suspended multi-role tactical decking and support system.

The 4x4 to 4x6 extender system is a variant of our tracked system. It comprises a single unit device consisting of two swingarm suspended wheels (matching vehicle) and a chassis incorporating support systems such as baffled fluid tanks, generators, pumps, tools, UAV launch systems, MEDEVAC equipage or weapons.

A typical configuration (example) is the StrikeRazor incorporating the extender with a solar water purification system and the 75 gallon tank. This system would allow remotely sighted teams to have access to purified water and the added ability to transport the purified water to other remote locations. When the mission is complete, the extender can be disconnected for future use, thus allowing the base tactical vehicle to return to it's primary role.

The extender is completely portable and can be fitted to numerous SxS LTV/ATV platforms (StrikeRazor, Ranger, MVP, Teryx, Commander, Prowler, Grizzly and many more) using basic tools in minutes.  When no longer needed, the vehicle mounted soldier has the option to remove the extender system and restore StrikeRazor (or other like vehicle) to the original 4-wheeled configuration.
