About Suspension Bases

Suburban Seating & Safety, a leading supplier of truck replacement parts, carries a variety of replacement air suspension bases from trusted names in the industry like National Seating, Bostrom, and Seats Inc. Air suspension systems provide a smoother ride and improved towing capabilities compared with spring suspension systems, which can weigh down large loads. Seat suspension takes the driving experience to a new level, allowing for hours of support and comfort, thanks to ergonomic designs and adjustability.


As with all parts, air suspension systems can break down over time through normal wear and tear. Suburban Seating & Safety is your trusted online retailer for replacement air suspension bases. With our exclusive catalog of name-brand seat accessories, you can find an air suspension seat base that suits your fleet best, from the following manufacturers:


National Seating

In addition to seats in vinyl, leather, or cloth, air suspensions that easily bolt in are available. Find low-profile suspension kits that fit your fleet trucks, with a 4-inch stroke, designed just for Freightliner applications. We have suspension seat base models built just for Ford, Dodge, and Chevy Kodiak trucks. When it comes to comfort, durability, and safety, National Seating is at the top of the list.



Bostrom is an innovator when it comes to seat suspensions. Its technology has even been used in mattresses, so you can bet our Bostrom Liberty and Liberty II Series replacement seat suspension kits will provide optimal comfort. They come with all the brackets, screws, and nuts required for a secure installation. The company’s innovations include hydraulic suspension and torsion suspension seats for medium-duty and large trucks.


Seats Inc

Seats Inc designs and manufactures truck seats for a wide range of applications. Suburban Seating & Safety offers a heavy-duty, yet low-profile air suspension seat base (the Mark I A) with a boot and heavy-duty shock absorber and self-lubricating bearings, and which adjusts to the ride and driver’s weight. The brand includes trusted mechanical suspensions, but its air suspension semi-truck parts are right there at the top.


Each seat suspension offers sufficient travel for optimal shock absorption. Browse our selection of truck replacement parts and truck accessories and choose from nationwide shipping or pick up at our New Jersey showroom, conveniently located near several major highways.
