In the fall of 2008, TIV 2 received several modifications, mostly focused on reducing the vehicle's weight. To achieve this, certain less crucial areas of TIV 2's armor were converted from steel to aluminum while more vital areas were reinforced with supplemental composite armor consisting of thin layers of steel, Kevlar, polycarbonate, and rubber. In all, the weight reduction measures brought TIV 2's weight down to . The safety systems were also improved, with the three front wind skirts being consolidated into one and new hydraulic stabilizing spikes to further increase stability in high winds. Other modifications included additional doors that provided every seat position with an exit (wind skirts up or down), and a redesigned IMAX turret with 50% more windows. The third axle was disconnected from the drive train, thus changing TIV2 to 6×4 from its 6×6 design. The third axle now acts as a brace for the vehicle's weight.
