Frequently Asked Questions About Kenworth Cabover Front Axle Air Ride Kits

What model years and specific Kenworth cabover models are these air ride kits compatible with?

Our front axle air ride kits are designed for Kenworth K100 and K100E cabovers manufactured from 1963 through 1990. They're compatible with both short hood and aerodyne models. For W900A cabovers (1961-1966), please verify your front axle configuration before ordering, as some early models may require additional brackets. Always check your VIN and axle model number against our compatibility chart or contact our tech support team for verification.

How difficult is the installation process, and what tools or professional help will I need?

Installation typically takes 6-8 hours for experienced mechanics and requires basic shop tools including air tools, torque wrenches, and jack stands rated for commercial trucks. The kit includes detailed instructions, but you'll need to safely support the front axle while removing the original springs. Most customers report needing assistance with spring removal and air line routing. Professional installation is recommended if you're not comfortable working with heavy suspension components or air brake systems. Budget approximately $400-600 for professional installation at most truck shops.

What's included in the complete kit, and will I need to purchase additional components?

Each kit includes air bags, mounting brackets, air valves, DOT-approved air lines, fittings, and installation hardware. You'll also receive detailed instructions and a parts diagram. Additional items you may need include thread sealant, air system cleaner, and possibly new U-bolts if yours show wear. Some installations require a separate height control valve (sold separately) if you want automatic leveling. The kit does not include an onboard air compressor - it connects to your existing truck air system.

What kind of ride improvement and load capacity can I expect with these air ride conversions?

Customers typically report a 40-60% reduction in cab bounce and vibration compared to steel springs. The air bags provide progressive spring rates that automatically adjust to load conditions, improving both empty and loaded ride quality. Load capacity matches or exceeds your original spring rating, with most kits supporting 12,000-14,000 lbs front axle weight. The system maintains proper ride height regardless of load, reducing tire wear and improving handling stability.

How durable are these air bags, and what maintenance do they require?

The air bags are constructed from four-ply reinforced rubber with steel bead plates, designed for 500,000+ mile service life under normal conditions. They're tested to withstand temperatures from -40F to 180F and operating pressures up to 100 PSI. Maintenance involves monthly visual inspections for rubbing or damage, keeping them clean of road chemicals, and checking air pressure weekly. Most failures occur from improper installation or debris damage rather than normal wear. Replacement bags are readily available and can typically be changed in under 2 hours per side.
