Exclusive, Patented ▲ Ride Technology

No Shocks Needed Available on select VANTRAAX ® and INTRAAX ® systems and standard on ULTRAA-K ® systems, ZMD eliminates conventional shock absorbers and integrates the damping function into the air spring. ZMD air springs exchange pressurized air through channels that interconnect the bellows and piston of this patented air spring.

Uniform Damping, Reduced Maintenance

With a reputation for innovative ride solutions, Hendrickson once again raises the bar with its patented ZMD ® ZERO MAINTENANCE DAMPING ® technology. ZMD is only available through Hendrickson and ushers in a new era of superior ride quality and enhanced maintenance savings.

Unlike a shock absorber whose damping capacity is finite and deteriorates with age, ZMD air springs are designed to provide continuous damping over the life of the air spring. Robust down stops provide maximum durability which helps reduce labor, costs and maintenance over the life of the trailer.
