Frequently Asked Questions About Peterbilt 587 Air Springs & Level Valves

Will these air springs fit my specific year model Peterbilt 587?

Most air springs and level valves for the Peterbilt 587 are compatible with model years 2011-2017. However, there can be variations based on your truck's suspension configuration (standard vs. low air leaf). Always verify your existing part numbers or provide your VIN when ordering to ensure proper fitment. Pay special attention to whether your 587 has the proprietary Peterbilt Air Suspension or aftermarket systems like Hendrickson or Firestone.

How difficult is it to install air springs and level valves myself?

Installation typically requires 2-4 hours per axle for someone with moderate mechanical experience. You'll need basic hand tools, jack stands, and ideally an air compressor to test the system. The most challenging aspects are safely supporting the frame while removing old springs and properly torquing the mounting bolts to specification (typically 45-65 ft-lbs). Many drivers recommend having a helper for alignment during installation. Professional installation usually runs $200-400 per axle if you prefer to have it done at a shop.

What's the difference between OEM and aftermarket air springs for my 587?

OEM Peterbilt air springs typically use Continental ContiTech or Firestone manufacturing and come with a 2-year warranty. Aftermarket options from brands like Goodyear, Air Lift, and Hendrickson often cost 30-50% less while maintaining similar quality rubber compounds and steel end plates. The main differences are warranty length (usually 1 year for aftermarket) and minor variations in ride height adjustment range. Most professional drivers report no noticeable performance difference between quality aftermarket and OEM springs.

How do I know when my level valves need replacement?

Common signs include uneven ride height side-to-side, slow or no height adjustment when loading/unloading, air leaks from the valve body, or one side sitting higher than the other when parked. A properly functioning level valve should maintain consistent ride height within 1/2 inch and respond to load changes within 10-15 seconds. If you're experiencing porpoising, excessive body roll, or hear constant air cycling, your level valves likely need adjustment or replacement.

Can I upgrade to heavy-duty air springs if I frequently haul at maximum capacity?

Yes, heavy-duty air springs with reinforced rubber compounds and additional steel belting are available for 587s that regularly operate at 70,000+ lbs GVW. These HD versions typically have 20-30% higher pressure ratings (120-130 PSI vs standard 100 PSI) and feature thicker sidewalls. Popular upgrades include Firestone W01-358-9625 for drive axles and Continental 64229 for steer axles. Keep in mind that upgrading springs alone won't increase your legal weight capacity but will improve ride quality and spring longevity under heavy loads.
