Frequently Asked Questions About Kenworth T880 Air Springs & Level Valves

What model years of the Kenworth T880 are these air springs and level valves compatible with?

Our air springs and level valves are designed to fit Kenworth T880 models from 2013 to present. However, compatibility can vary based on your specific truck configuration, including suspension type (Airglide, Airtek, or Flex Air) and axle weight ratings. We recommend checking your VIN or contacting our support team with your truck's specifications to ensure proper fitment before ordering.

How difficult is it to install air springs and level valves on my T880, and what tools will I need?

Installation typically takes 2-4 hours per axle for experienced mechanics. You'll need basic hand tools, jack stands, and an air compressor. The most challenging part is often accessing the upper mounting bolts and properly aligning the level valve linkage. Many customers report that having a second person helps significantly. While professional installation isn't required, we recommend it if you're not comfortable working with air suspension systems, as improper installation can lead to ride height issues or premature failure.

What's the difference between OEM and aftermarket air springs for the T880, and how does it affect longevity?

OEM air springs typically last 200,000-300,000 miles under normal conditions, while quality aftermarket options from brands like Firestone and ContiTech offer similar lifespans at 20-30% less cost. The main differences are in rubber compound quality and reinforcement design. Aftermarket springs may require slightly more frequent inspection but provide excellent value. Avoid ultra-budget options under $100 per spring, as these often fail within 50,000 miles due to inferior materials.

How do I know if my level valve needs replacement versus just adjustment?

A properly functioning level valve should maintain consistent ride height within 1/4 inch when loaded or unloaded. Signs of failure include: truck leaning to one side, constant air bleeding, inability to maintain height overnight, or excessive bouncing. Before replacing, try adjusting the linkage arm - many issues are simply misalignment. If adjustment doesn't resolve the problem or you see physical damage like cracks or worn pivot points, replacement is necessary. Level valves typically last 300,000-500,000 miles with proper maintenance.

What maintenance schedule should I follow for T880 air springs and level valves to maximize their lifespan?

Inspect air springs visually every 30,000 miles for cracks, abrasions, or bulging. Check level valve linkage for proper adjustment and free movement every 60,000 miles. Keep springs clean of road chemicals and debris, especially in winter months. Apply rubber protectant spray every 6 months to prevent dry rot. Most importantly, maintain proper air pressure (typically 60-100 PSI depending on load) and address any leaks immediately. Following this schedule can extend component life by 30-40% compared to neglected systems.
