Hendrickson has released the Primaax EX system, an enhanced version of its heavy-duty vocational truck air suspension. It delivers improved durability and performance, and is lighter than competitive models, according to the company.
Primaax EX features enhanced joint integrity and durability, improved handling, increased air spring capacity, greater disc brake compatibility and improved resistance to torque rod bushing walk-out, Hendrickson said.
In addition, cast austempered and shot-peened ductile iron support beams provide greater reliability, and a new frame hanger and torque rod configuration improves handling, the company said.
Primaax EX is available in capacities ranging from 23,000 to 26,000 lbs. for single-axle, 46,000 to 52,000 lbs. for tandem-axle and 69,000 to 78,000 lbs. for tridem-axle applications.
