“The unique design of our LSZ offers unmatched durability and reliability for our customers,” said Jack Gisinger, president-- Powered Vehicles Business Unit. “Overall, the compact size combined with superior ride and low maintenance delivers improved operating efficiency.”
Per the company, the system’s 17.5-in package size makes the system a minimum of 4 in up to 10 in shorter than comparable lift axles to “offer customers application versatility and enable easy installation and service as well as provide extra frame rail space for component packaging and options.”
The Super Chamber lift on the LSZ outperforms traditional air springs by providing a quick and reliable four-second lift speed, said SAF-Holland, noting that “this unique design is more durable than competitive lifts and provides a stronger and more consistent lift force that keeps the axle securely stowed.” The Super Chamber position also “provides increased protection from road hazards and easier access for servicing.”
The LSZ’s rolling lobe air springs are positioned at an angle, to “deliver a superior spring rate for increased stability and ride quality” and its parallelogram design “maintains precise steering geometry while reducing tire wear.”
Other features of the new system include a kingpin assembly with spherical bearings that eliminate thrust bearings that often require shimming and reaming. As a result, service requirements are greatly reduced, noted the company.
