ArvinMeritor's Commercial Vehicle Systems (CVS) announced the availability of 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. The composite spring assembly is more durable and provides a significant weight and cost savings. It also offers less maintenance than air suspensions, and is more corrosion resistant than steel springs.
