Frequently Asked Questions About Freightliner Coronado Air Springs & Level Valves
What years and models of Freightliner Coronado are these air springs compatible with?
Our air springs and level valves are designed to fit Freightliner Coronado models from 2001 to current production years. However, compatibility can vary based on your specific truck configuration, including SD (Set-Back Axle) or SF (Set-Forward Axle) models, and whether you have a day cab or sleeper configuration. We recommend checking your VIN or existing part numbers before ordering, as some 2001-2009 models may have different mounting specifications than 2010+ models.
How difficult is it to install these air springs, and what tools do I need?
Installation typically takes 2-4 hours per axle for someone with moderate mechanical experience. You'll need basic hand tools including wrenches (typically 3/4", 7/8", and 1"), a floor jack or lift, jack stands, and air line disconnect tools. The most challenging part is usually removing the old air springs if they're seized or corroded. We strongly recommend having the truck's air system depressurized and properly supported before beginning. Many customers report that having a second person helps significantly during alignment of the new springs.
What's the difference between OEM and aftermarket air springs, and which should I choose?
OEM air springs typically use reinforced rubber compounds with crimped steel end plates and come with manufacturer warranties ranging from 1-3 years. Aftermarket options often feature similar construction but may use different rubber formulations or coating processes. The main differences you'll notice are in price (aftermarket is usually 30-50% less expensive) and longevity. OEM springs generally last 200,000-300,000 miles under normal conditions, while quality aftermarket options typically achieve 150,000-250,000 miles. For trucks under warranty or in severe-duty applications, OEM is recommended. For standard highway use, quality aftermarket brands provide excellent value.
How do I know if my level valve needs replacement along with the air springs?
Level valves should be inspected whenever replacing air springs. Signs of a failing level valve include: uneven ride height side-to-side, the truck not returning to proper ride height after loading/unloading, excessive air consumption, or visible damage to the valve linkage. If your truck has over 500,000 miles and you're replacing air springs due to age, it's often cost-effective to replace the level valve simultaneously since labor overlap makes installation more economical. A properly functioning level valve is crucial for maintaining correct ride height and preventing premature air spring failure.
What's included in a complete air spring kit, and what additional parts might I need?
A complete air spring kit typically includes the air spring assembly with integrated mounting studs and air fitting. However, you may need additional components not always included: new air lines (if existing ones are cracked or damaged), mounting bolts (if corroded), and air fittings (1/4" or 3/8" NPT are common). Some kits include these items while others don't. We recommend having thread sealant or Teflon tape on hand for air connections. If you're replacing springs due to failure rather than preventive maintenance, inspect shock absorbers as well, since worn shocks can accelerate air spring wear.
