Frequently Asked Questions About Freightliner FLC120 Air Springs & Level Valves
What years and models of FLC120 are these air springs compatible with?
Our air springs and level valves are designed to fit Freightliner FLC120 models from 1988 through 2003. However, compatibility can vary based on your specific truck configuration, including whether you have a single or tandem axle setup, and your suspension type (Hendrickson, Neway, or Reyco). We recommend checking your existing part numbers or contacting our support team with your VIN to ensure proper fitment.
How difficult is it to install air springs on my FLC120, and what tools do I need?
Installation typically takes 2-4 hours per axle for someone with basic mechanical skills. You'll need standard hand tools including wrenches (typically 3/4" and 7/8"), a floor jack, jack stands, and an air compressor to test the system. The most challenging part is often accessing the upper mounting bolts in tight spaces. Many customers report that having a second person helps significantly, especially when aligning the new air springs during installation.
What's the difference between OEM and aftermarket air springs for the FLC120?
OEM air springs typically use reinforced rubber compounds with steel-belted construction and come with a 2-3 year warranty. Aftermarket options vary widely in quality - premium aftermarket brands like Firestone or ContiTech often match OEM specifications and cost 30-40% less, while economy options may use thinner rubber walls and have shorter lifespans. We carry both OEM replacements and trusted aftermarket brands, clearly labeled with warranty information.
How do I know if my level valve needs replacement along with the air springs?
Common signs of a failing level valve include uneven ride height between sides, slow air leak when parked, excessive bouncing, or the truck not returning to proper ride height after loading/unloading. If your air springs failed due to over-extension or rubbing, this often indicates a level valve issue. We recommend replacing level valves every other air spring change as preventive maintenance, as a failed valve can cause premature air spring failure.
What maintenance can I do to extend the life of my FLC120 air springs?
Regular inspection every 3 months is crucial - look for cracks, abrasions, or unusual wear patterns. Keep the air springs clean and free from oil or grease contamination, which can deteriorate the rubber. Maintain proper ride height (typically 8-10 inches depending on your setup) to prevent over-extension. Check and adjust your level valve linkage annually, and ensure your air system maintains 90-120 PSI. Properly maintained air springs typically last 3-5 years in normal highway use, or 2-3 years in severe duty applications.
