TAG AXLE SUSPENSION
SYSTEM
®
Freightliner Chassis
Your coach may be equipped with a Tag Axle
Suspension System, which is designed to
increase the Gross Vehicle Weight Rating
(GVWR). This system is to be used when the rear
suspension/axle will be loaded to a weight
greater than 20,000 lbs. When certain conditions
arise, air can be exhausted from the air springs to
improve maneuverability or traction on the rear
axle by operating the Tag Axle switch (located on
the driver side trim panel).
