Frequently Asked Questions About Ford F650-F750 Truck Air Springs & Level Valves
Will these air springs fit my specific F650 or F750 model year?
Air spring compatibility varies significantly across F650-F750 model years, particularly between pre-2016 and 2016+ models due to chassis redesigns. Most air springs are designed for specific year ranges such as 2000-2015 or 2016-present. Always verify your truck's exact year, GVWR rating, and suspension configuration before ordering. If you're unsure, check your VIN plate or contact us with your truck's specifications for accurate fitment guidance.
How difficult is it to install air springs and level valves on my F650/F750?
Installation typically requires 2-4 hours per axle for experienced mechanics. You'll need basic hand tools, jack stands, and ideally an air compressor for testing. The most challenging aspects include safely supporting the frame during spring removal and properly routing air lines to avoid heat sources and moving components. Level valve installation requires precise adjustment to maintain proper ride height. While DIY installation is possible with mechanical experience, professional installation is recommended to ensure proper function and avoid warranty issues.
What's the difference between OEM and aftermarket air springs for these trucks?
OEM air springs typically use reinforced rubber compounds and exact factory specifications but cost 30-50% more than aftermarket options. Quality aftermarket brands like Firestone and Continental ContiTech offer comparable durability with proper heat-resistant materials rated for 200+ PSI. The main differences are warranty length (OEM usually 2-3 years vs aftermarket 1-2 years) and minor variations in crimp ring design. Both options work well when properly installed and maintained.
How do I know if my level valve needs replacement versus just adjustment?
A properly functioning level valve should maintain consistent ride height within 1/2 inch when loaded. Signs of failure include: air constantly bleeding from the exhaust port, truck leaning to one side, frequent air compressor cycling, or inability to maintain pressure overnight. Before replacement, check the linkage arm for bent components and ensure mounting brackets haven't shifted. Many issues are resolved by proper adjustment using the valve's built-in height adjustment mechanism rather than full replacement.
What air pressure should I run in my F650/F750 air springs?
Proper air pressure depends on your truck's configuration and load. Empty trucks typically run 60-80 PSI, while loaded vehicles may require 100-120 PSI. Never exceed the maximum pressure stamped on your air spring (usually 120-150 PSI). Your door jamb sticker or owner's manual provides recommended pressures for your specific GVWR. Remember that front and rear pressures often differ, and maintaining proper pressure is critical for ride quality, handling, and spring longevity.
