Independent Suspension System


Featured on the M-ATV, LVSR, PLS A1, P-19R and MTVR platforms, the TAK-4 independent suspension system steadily thunders over whatever comes its way. Equipped with this suspension, the Oshkosh® MRAP All-Terrain Vehicle (M-ATV) quickly proved to be lighter with greater maneuverability and ride quality, while maintaining MRAP-level protection against threats. First used on the U.S. Marine Corps Medium Tactical Vehicle Replacement (MTVR), the Oshkosh TAK-4 family of independent suspension systems sets Oshkosh apart as the leader in off-road military mobility and has been applied to more than 25,000 tactical wheeled vehicles.
