Frequently Asked Questions About Peterbilt 387 Air Springs & Level Valves

What year models of Peterbilt 387 are these air springs and level valves compatible with?

Our air springs and level valves are designed to fit Peterbilt 387 models from 2000 to 2010. However, compatibility can vary based on your specific truck configuration, including whether you have a single or tandem axle setup. We recommend checking your existing part numbers or contacting our support team with your VIN to ensure proper fitment before ordering.

How difficult is it to install air springs and level valves on my Peterbilt 387?

Installation typically takes 2-4 hours for experienced mechanics and requires basic hand tools, jack stands, and potentially an air impact wrench. The most challenging aspects include safely supporting the truck frame, removing the old components without damaging air lines, and properly torquing the new mounting hardware. Many customers successfully complete DIY installations, but we recommend professional installation if you're not comfortable working with air suspension systems.

What's the difference between OEM and aftermarket air springs for my 387?

Aftermarket air springs often use the same rubber compounds and steel components as OEM parts but at a lower price point. The main differences include warranty coverage (OEM typically offers longer warranties), minor design variations in mounting brackets, and brand recognition. Our aftermarket options meet or exceed OEM specifications and carry manufacturer warranties ranging from 1-3 years depending on the brand.

How can I tell if my level valve needs replacement versus just adjustment?

Signs your level valve needs replacement include: air constantly bleeding from the exhaust port, inability to maintain ride height even after adjustment, visible damage to the valve body or linkage, and erratic height changes while driving. If your truck simply sits too high or low but maintains that height consistently, you likely just need a linkage adjustment rather than a full replacement.

What maintenance should I perform to extend the life of my air springs and level valves?

Regular maintenance includes: inspecting air springs monthly for cracks, bulges, or rubbing damage; checking and adjusting ride height every 3 months; keeping level valve linkages clean and lubricated with silicone spray; and ensuring proper air pressure (typically 60-100 PSI depending on load). Replace air springs in pairs to maintain balanced suspension performance, and always address air leaks promptly to prevent premature component failure.
