Frequently Asked Questions About Freightliner Cascadia 113/125 Air Springs & Level Valves

What year models of Freightliner Cascadia 113/125 are these air springs compatible with?

Our air springs and level valves are designed to fit Freightliner Cascadia 113 and 125 models from 2008 to present (2024). However, there are slight variations between pre-2018 and post-2018 models due to suspension updates. Always verify your specific truck's VIN and suspension configuration before ordering. Most products will specify whether they fit "Old Body Style" (2008-2017) or "New Body Style" (2018+) Cascadias.

How difficult is it to install air springs on my Cascadia, and what tools do I need?

Air spring replacement typically takes 2-4 hours per axle for someone with basic mechanical skills. You'll need standard hand tools including socket sets (typically 15mm-24mm), torque wrench, jack stands rated for commercial trucks, and a reliable floor jack. The most challenging part is safely supporting the truck while removing the old springs. Many drivers recommend having a helper for alignment during installation. Professional installation usually runs $200-400 per axle if you prefer not to DIY.

What's the difference between OEM and aftermarket air springs, and which should I choose?

OEM air springs from Freightliner typically last 300,000-500,000 miles but cost 30-50% more than quality aftermarket options. Aftermarket brands like Firestone, ContiTech, and Goodyear offer comparable durability at lower prices. The main differences are warranty length (OEM usually offers longer coverage) and exact fit specifications. For trucks out of warranty, most drivers report excellent results with premium aftermarket springs that meet or exceed OEM specifications.

How do I know if my level valve needs replacement along with my air springs?

Level valves should be inspected whenever replacing air springs. Signs of a failing level valve include: uneven ride height side-to-side, slow air leak when parked, excessive bouncing, or the truck not returning to proper ride height after loading/unloading. A properly functioning level valve should maintain consistent ride height within 1/4 inch. If your valve is over 5 years old or shows signs of air leakage around the linkage, it's cost-effective to replace it while doing the springs.

What's the typical lifespan of Cascadia air springs, and how can I maximize it?

Under normal operating conditions, quality air springs last 250,000-400,000 miles or 3-5 years. Factors affecting lifespan include load weight consistency, road conditions, and maintenance habits. To maximize lifespan: maintain proper air pressure (typically 60-100 PSI depending on load), inspect for rubbing or chafing monthly, keep the air system moisture-free with regular tank draining, and avoid overloading beyond your suspension's rated capacity. Springs used in construction or off-road applications may need replacement 30-50% sooner than highway-only trucks.
