Frequently Asked Questions About Kenworth T800 Front Axle Air Ride Kits

Will these air ride kits fit my specific year model Kenworth T800?

Most front axle air ride kits are designed to fit Kenworth T800 models from 1987 through 2007. However, compatibility can vary based on your truck's axle configuration, GAWR (Gross Axle Weight Rating), and whether you have a set-forward or set-back front axle. Before ordering, check your truck's VIN plate for the axle model number and verify the kit matches your specific FA (Front Axle) code. Common compatible axle models include Dana Spicer D2000F and Meritor MFS series.

How difficult is the installation process, and what tools are required?

Installation typically takes 4-6 hours for experienced mechanics and requires standard shop tools including impact wrenches, jack stands rated for commercial vehicles, and basic hand tools. The most challenging aspects involve properly positioning the air bags and ensuring correct ride height adjustment. Many drivers report needing to adjust the leveling valve linkage multiple times to achieve proper ride characteristics. Professional installation is recommended if you're not comfortable working with air brake systems, as improper installation can affect vehicle handling and safety.

What's the actual ride improvement I can expect with these kits?

Drivers consistently report 60-80% reduction in cab shake and bounce, particularly noticeable on rough roads and expansion joints. The air ride system significantly reduces driver fatigue on long hauls and helps protect sensitive cargo. You'll experience smoother steering input, less jarring over potholes, and reduced wear on front-end components. However, the improvement is most dramatic on trucks previously running worn-out OEM leaf springs.

Are these kits DOT approved and will they affect my truck's weight capacity?

Quality air ride conversion kits from reputable manufacturers are DOT compliant and maintain your truck's original GAWR when properly installed. The kits typically add 150-200 pounds to the front axle weight but don't reduce load capacity. Always verify the kit includes proper certification documentation and that the air bags are rated for your specific front axle weight rating, which typically ranges from 12,000 to 20,000 pounds on T800 models.

What maintenance is required and how long do these systems typically last?

Air ride systems require minimal maintenance beyond regular visual inspections for air leaks and checking air bag condition every 3-6 months. The air bags typically last 200,000-300,000 miles under normal use, though harsh conditions may reduce lifespan. Common maintenance items include replacing air line fittings if leaks develop and occasionally adjusting the leveling valve. Most drivers find the reduced wear on tires, steering components, and cab mounts more than offsets the minimal maintenance requirements.
