Family of Independent Suspension Systems

There are no compromises. And absolutely no comparisons.

Scale a rocky slope. Outmaneuver the enemy. Haul equipment with capacity to spare. Nothing should stand in the way of the mission. The patented Oshkosh® TAK-4® family of independent suspensions gives any vehicle – from light tactical trucks to heavy equipment transporters – the protection, mobility and payload capacity to effectively complete demanding missions.
Our experts leverage decades of ground operations experience and unmatched vehicle knowledge to design and deliver superior suspension systems. We understand what it takes to protect crews, achieve higher speeds, haul the heaviest loads and overcome harsh terrain. Over and over, TAK-4® suspensions deliver scalable solutions to improve ride quality, protection and mobility.

TAK-4® | Independent Suspension System

S-CAM or wedge drum brakes

Standard coil spring option

Hydro-pneumatic spring option

High-pressure gas (HPG) spring option

Up to 16 in. (40.6 cm) independent wheel travel

Performance Over and Above All Obstacles Ahead
Featured on the M-ATV, LVSR, PLS A1, P-19R and MTVR platforms, the patented 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.
