Frequently Asked Questions About Kenworth T660 Front Axle Air Ride Kits

Will these air ride kits fit my specific year model T660, and are there any compatibility issues I should know about?

Our front axle air ride kits are designed to fit Kenworth T660 models from 2008-2016. However, compatibility can vary based on your truck's original suspension configuration and front axle weight rating. Trucks with factory air ride may require different components than those converting from leaf spring suspensions. We recommend checking your VIN-specific build sheet or calling our tech support at 1-888-875-2425 with your truck's details to ensure proper fitment.

How difficult is the installation process, and what tools or expertise do I need?

Installation typically takes 4-6 hours for an experienced technician. You'll need standard shop tools including impact wrenches, jack stands rated for commercial vehicles, and basic hand tools. The most challenging aspects involve properly aligning the air bags and ensuring correct ride height adjustment. While many owner-operators successfully install these kits, we recommend professional installation if you're not comfortable working with air systems or heavy suspension components. Most kits include detailed instructions, but expect to drill mounting holes in some applications.

What's the actual ride quality improvement, and how does it affect my truck's handling?

Drivers typically report a 40-60% reduction in cab bounce and vibration compared to factory leaf springs. The air ride system provides better shock absorption over rough roads and reduces driver fatigue on long hauls. You'll notice the most improvement on expansion joints, railroad crossings, and deteriorated highway surfaces. The system maintains consistent ride height regardless of load, though some drivers note slightly different steering feel during the first few hundred miles as they adjust to the smoother ride characteristics.

What maintenance do these air ride systems require, and what are common failure points?

Air ride systems require minimal maintenance beyond regular visual inspections. Check air bags for cracks or wear every 3 months, ensure all air lines are secure and free from chafing, and drain moisture from the air system weekly. Common issues include air bag dry rot after 5-7 years (depending on climate), fitting leaks at connection points, and height control valve sticking in extremely cold weather. Keep spare air line fittings on hand, as these are the most frequent minor repair items. Most air bags carry a 2-year warranty against defects.

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

Complete kits typically include air bags, mounting brackets, air lines, fittings, height control valve, and installation hardware. However, you may need to purchase separately: shock absorbers (if upgrading from leaf springs), air tank and compressor upgrades (if your current system lacks capacity), and ride height gauge for the dash (optional but recommended). Some conversions also require frame rail reinforcement plates, depending on your truck's configuration. Each product listing specifies exactly what's included, but budget an additional $200-500 for potential ancillary components.
