SWB

The SWB tandem steer suspension is a spring over walking beam suspension design with a focus on reduced maintenance costs. It starts with better alignment. The SWB tandem steer reduces the number of wear points - from ten in a traditional 4-spring suspension, to just two. In addition, the SWB tandem steer ensures better load equalization by using walking beam technology. Other benefits include:
• Reduced Tire Wear due to better load equalization
• Patented front walking beam construction, just like on the premium Air Link
• Polyurethane bushings provide longer service life
• 10%-20% lighter than many other leading OEM 4-springs
The SWB (Spring Walking Beam Tandem Steer Suspension) is new to the market, but is built on proven technologies. The design is a hybrid that blends the rugged durability and weight distribution of our premium Air Link® walking beam with the simplicity of a spring suspension. This combination gives you improved ride quality along with reduced maintenance costs as compared to a traditional four spring configuration. And, the straightforward design allows reduced installation time. So you get a better performing suspension at a comparable cost to a basic four spring.
