1. Sleeve-style air springs are designed for lift and ride control. The internally mounted sleeve is covered by a bag, made of flexible, heavy-gauge rubber. The bag is crimped into the spring mount on one end and swaged onto the opposite end, sealing the contents inside. 2. When air is compressed into the spring, the two-piece sleeve extends, lengthening the assembly to achieve the desired ride height. 3. Sleeve style air springs are extremely well suited for applications when space is limited, and loads are light. Sleeve-style air springs are perfect for light-duty trucks, custom street rods and track cars.Guangzhou Viking Auto Parts Co.,Ltd was founded in 2009 and located in Conghua pearl industry park, Guangzhou city, covering 30,000 square meters with annual production capacity can reach to 1 million pieces .

Bellows style Bellows-style air springs are made from heavy-duty, reinforced rubber which is configured with either one or more convoluted chambers. These air bags are typically larger than sleeve-style air springs, giving them greater load-handling capacity. Because of their size and shape, bellows-style air springs can lift the same weight with about half the air pressure of sleeve-style springs. The most popular bellows-style air spring configurations include single, dual, and triple chamber design. Bellows air springs are great for heavy-duty applications as long as there is plenty of space for proper installation.
