Frequently Asked Questions About Peterbilt 362 Air Springs & Level Valves
What do air springs and level valves actually do on my Peterbilt 362?
Air springs (also called air bags) support the weight of the cab or suspension and absorb road shock by inflating and deflating with compressed air. Level valves regulate airflow into and out of the air springs to keep the ride height consistent as load and road conditions change. Together, these components keep your cab or axle riding level and help reduce vibration and wear on other parts of the truck.
How do I know if my air spring or level valve is failing?
Common signs include a cab or axle that sits noticeably lower on one side, a rougher ride than usual, audible air leaks near the suspension or cab mounts, or the compressor running more frequently to maintain pressure. If you notice uneven ride height that does not self-correct, the level valve linkage or the air spring itself may need to be inspected.
Will these air springs and level valves fit my specific Peterbilt 362 configuration?
Air spring and level valve fitment can vary based on cab suspension type, axle configuration, and model year, so it is important to match the part number to your truck's specifications rather than assuming universal fit. Check the listed application details on each product page, and compare against your existing part's numbers or your truck's service documentation before ordering.
Are these replacement parts OEM or aftermarket, and does it matter?
We carry a mix of OEM and quality aftermarket air springs and level valves. Aftermarket parts are built to match OEM specifications for fit and performance, often at a lower cost. If you have a preference for original manufacturer parts, check the product description and title, as this is typically noted there.
Do I need to adjust the level valve linkage after installing a new air spring?
Yes, in most cases. After replacing an air spring or level valve, the linkage arm typically needs to be reset so the valve reads ride height correctly. An improperly adjusted linkage can cause the cab or suspension to sit too high, too low, or fail to level out properly, so it is worth double-checking this step during installation.
