DESCRIPTION
Keep your Peterbilt cab riding smooth and stable with the ROADWEST Cab Air Spring Bag, engineered as a direct replacement for popular OEM and aftermarket part numbers such as Firestone W02-358-7036 and Peterbilt 29-03200 / 2902454. This sleeve-style air spring is designed for select Peterbilt highway tractors that use these cab suspension air bags, helping restore proper ride height and comfort for long-haul drivers.
Built with imported high-density rubber and heavy-duty end components, this cab air spring is made to handle constant load changes, road vibration and harsh working conditions. The robust construction delivers reliable support for the cab and sleeper, helping reduce driver fatigue and improving steering stability over rough pavement, construction zones and long interstate runs.
As a direct cross-reference to W02-358-7036 and related numbers, the ROADWEST cab air spring matches the key mounting dimensions and air volume of the original bag. That means you can replace a worn, cracked or leaking original air spring without special modifications. In most applications, installation is a straightforward remove-and-replace job for professional repair shops or experienced fleet technicians.
Whether your truck is used for regional haul, OTR long haul or heavy-duty vocational work, replacing tired cab air springs helps reduce vibration transfer into the cab, protect interior components and keep drivers more alert and comfortable.
