The MEGATRAK™ suspension system is the best off road driveline available on the market today. The system’s versatility and performance allows the GMK5225 to operate as a true all-terrain crane. The MEGATRAK™ independent suspension and all-wheel steer system allows wheels to remain on the ground at all times so stresses and weight are not continually transferred between axles. MEGATRAK™ provides true ground clearance where others just raise the chassis.

Other benefits of the MEGATRAK™ system are:

  • A reliable suspension system
  • Excellent job site maneuverability with all-wheel steering
  • Commonality among almost all models
  • A driveline that remains aligned at all times
  • A steering linkage system that is protected against damage
  • Constant tire contact for equal tire wear
  • Reduced maintenance
