New Meritor Composite Trailer Spring Improves Ride and Maintenance

19 February 2006

ArvinMeritor’s Commercial Vehicle Systems business has introduced its new Meritor SimilAir Composite Trailer Spring for linehaul and general service applications.

The Meritor SimilAir is a composite mechanical spring that delivers ride quality close to that of an air suspension with much lower initial and life cycle costs.

“Meritor’s SimilAir is breakthrough technology that delivers the smooth ride operators expect from an air suspension without the added maintenance, weight and cost,” said Robert Zirlin, director of Product Planning and Development for North American Trailer Products. “What sets this spring apart from other mechanical systems is its composite material, which offers numerous performance and bottom-line advantages to fleets and end-users.”

The composite spring assembly is more durable and provides a significant weight and cost savings. Suspensions equipped with this new composite spring weigh as much as 240 lbs. less than the lightest air suspensions, and over 100 lbs. less than popular mechanical suspensions. It also offers less maintenance than air suspensions, and is more corrosion resistant than steel springs.

The Meritor SimilAir Composite Spring was originally targeted at mechanical suspension users who were considering air ride suspensions, but did not want the cost penalty and maintenance requirements. During field evaluations, it attracted significant interest on the part of current air suspension users as well.

“While composite springs have been available on mechanical trailer suspensions for many years, they have represented a niche of extremely weight sensitive customers,” said Zirlin. “By optimizing the ride quality and overall performance offered, the new Meritor SimilAir spring has much broader market appeal.”

Meritor SimilAir is a joint effort between ArvinMeritor and Liteflex, LLC. The two companies announced, last month, the signing of a long-term agreement granting ArvinMeritor exclusive distributorship of Liteflex truck, trailer and specialty vehicle composite mechanical springs for North America and several other key global markets.
