Description and Purpose

The Volvo / Mack® Air Suspension Spring Assembly (Part Number: 25173616) is designed to provide a smooth and controlled ride by absorbing road shocks and maintaining consistent vehicle height. This rolling lobe air spring is engineered for durability and optimal load distribution, making it essential for commercial trucks and heavy-duty applications.

Why Replacement is Important

Worn or damaged air springs can lead to reduced ride quality, uneven weight distribution, and increased strain on other suspension components. Replacing the air suspension spring assembly restores proper vehicle handling, prevents excessive vibration, and extends the lifespan of suspension and drivetrain parts.

Impact on Vehicle Performance

A fully functional air suspension system improves stability, enhances driver comfort, and reduces wear on tires and axles. With a bellows number of 9 10-18.5 and a compressed height of 7.54 inches, this air spring ensures consistent performance under varying load conditions. Its durable plastic bottom plate, along with secure top and bottom stud mounts, provides long-lasting reliability, making it ideal for heavy-duty trucking operations.

Manufacturer Information:

Mack Trucks, Inc. is a historic American truck manufaccturer, widely recognized for its durable and heavy-duty commercial vehicles. The company was originally founded in 1900 as the Mack Brothers Company and produced its first truck in 1905. In 1922, the company officially adopted the Mack Trucks nama, solidifying its brand in the trucking industry.

Throughout its history, Mack has been a major player in heavy-duty truck production and was also involved in manufacturing buses and trolleybuses. In 2000, Mack Trucks became a subsidiary of Volvo, following its acquisition along with its former parent company, Renault Véhicules Industriels.

Originally established in Brooklyn, New York, Mack moved its headquarters to Allentown, Pennsylvania, in 1905, where it remained for over a century. In 2009, the company relocated its headquarters to Greensboro, North Carolina, where it continues its legacy of producing reliable and powerful trucks for global markets.
