Features MEGATRAK™ The MEGATRAK™ suspension system is the best off road driveline available on the market today. The system’s versatility and performance allows the GMK5275 to operate as a true all-terrain crane.

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...
