In today’s trucking industry, we know our customers have many choices. In order for us to earn and retain your business, we have to be better at what we do than our competition.  In the early ’50s tag axles were gaining in popularity, but it soon became apparent that they lacked in traction. In an effort to address this problem, a company was started in 1953 in Sioux City, Iowa, producing large pulleys to be installed between the dual tires of the drive axle and tag axle. By connecting these pulleys with a large V-belt, the drive axle powered the tag axle. 2222  Since the tag axle was powered by silent V-belts instead of noisy gears, the company was called Silent Drive. By the early 70’s, Silent Drive’s suspension lifts were edging out V-belt drives in the marketplace, creating an opportunity to expand product lines, and soon required more space in the factory. In 1974, a new plant was built in Orange City, Iowa, and all operations were moved to this new location.  Since that time, Silent Drive has been the innovative leader in the suspension industry. We were the first to use automatic leaf spring-lifts in the suspension. Additionally, the professionals at Silent Drive pioneered the concept of unitizing the suspension to an axle for a complete, ready-to-install system.

The underarm air spring lift concept was developed by the Silent Drive engineering team, and has been adopted by nearly every suspension manufacturer in the nation. Commitment to quality and innovation keeps Silent Drive one step ahead of their competition.  Silent Drive has grown from a regional manufacturer, supplying products primarily for the agricultural market, to an industry leader, manufacturing air suspensions for liftable tags and pushers, drive axle suspensions, as well as primary and auxiliary lift axles on trailers. Using state of the art technology like Pro-E and Finite Element Analysis for design and testing also allows us to provide custom built systems tailored to specific needs or applications.  Expect the most complete product line, capacities from 8,000 to 30,000 pounds, axle lifts from 6 to 18 inches, patented Uroflex pull arm bushings, and excellent customer service from the industry leader. Our reputation for a quality product at a fair price has carried our business across the United States and into Canada. Our experience, adaptability, innovative leadership, and commitment to quality keeps us a step ahead of the competition.
