Frequently Asked Questions About Freightliner FL70-FL80 Air Springs & Level Valves
What years and models are these air springs compatible with?
Our air springs and level valves are designed to fit Freightliner FL70 and FL80 models from 1994 through 2007. However, compatibility can vary based on your truck's specific suspension configuration. We recommend checking your existing air spring part numbers or contacting us with your VIN to ensure proper fitment. Some models with aftermarket suspension modifications may require different components.
How difficult is it to install these air springs myself?
Installation typically takes 2-4 hours per axle for someone with basic mechanical skills. You'll need standard hand tools, jack stands, and ideally an air compressor to test the system. The most challenging part is usually removing the old air springs if they're corroded or seized. We strongly recommend having a second person help support the axle during installation. If you're not comfortable working with air suspension systems, professional installation is advisable as improper installation can affect ride height and vehicle stability.
What's the difference between OEM and aftermarket air springs for my FL70/FL80?
OEM air springs typically last 5-7 years and maintain exact factory ride specifications. Our aftermarket options often use reinforced rubber compounds and improved crimp rings that can extend service life to 7-10 years. While aftermarket springs may have slightly different dimensions, they're engineered to maintain proper ride height and load capacity. The main advantage of aftermarket is usually better pricing and availability without sacrificing quality or performance.
How do I know when my level valve needs replacement versus adjustment?
If your truck leans to one side, sits too high or low, or takes excessive time to level after loading, start with a simple adjustment. However, if you notice air leaking from the valve body, inconsistent ride height that changes while driving, or the valve arm is bent or damaged, replacement is necessary. A properly functioning level valve should maintain consistent ride height within 1/2 inch and respond to load changes within 10-15 seconds.
What maintenance do these air springs require to maximize their lifespan?
Inspect air springs monthly for cracks, abrasions, or unusual wear patterns. Keep them clean from road salt and debris using mild soap and water. Check air pressure weekly - running with low pressure is the leading cause of premature failure. Apply rubber protectant spray every 3-6 months to prevent dry rot. Most importantly, address any air leaks immediately as running the compressor excessively will damage both the springs and your air system components.
