Frequently Asked Questions About Kenworth T660 Drive Axle Springs & Hangers

What model years do these drive axle springs and hangers fit?

Our Kenworth T660 drive axle springs and hangers are designed to fit model years 2008-2016. However, compatibility can vary based on your specific axle configuration and suspension type. We recommend checking your truck's VIN or contacting our support team with your truck's specifications to ensure proper fitment before ordering.

Are these springs rated for heavy-duty applications?

Yes, our drive axle springs are manufactured to meet or exceed OEM specifications for heavy-duty commercial use. Most springs in our inventory are rated between 20,000 to 46,000 pounds per axle, depending on the specific model. Each product listing includes the exact weight rating and capacity specifications. For severe-duty applications or specialized hauling needs, we recommend selecting springs rated at least 10% above your typical loaded weight.

Do I need special tools or equipment to install these springs and hangers?

Installation requires standard heavy-duty suspension tools including a spring compressor, torque wrench capable of 450-500 ft-lbs, and proper jack stands rated for commercial trucks. You'll also need new U-bolts (sold separately) as reusing old U-bolts is not recommended for safety reasons. While experienced mechanics can complete the installation in 3-4 hours per axle, we strongly recommend professional installation if you're not familiar with heavy truck suspension systems.

What's the difference between OEM and aftermarket springs for my T660?

OEM springs are manufactured to Kenworth's exact specifications and typically carry a higher price point. Our aftermarket options are produced by reputable manufacturers like Dayton Parts and meet or exceed OEM standards while offering cost savings of 20-40%. Both options use high-grade spring steel and similar heat treatment processes. The main differences are price and availability - aftermarket springs are usually in stock and ship faster.

How do I know when my drive axle springs need replacement?

Common signs include visible cracks in the spring leaves, broken or missing leaves, uneven truck height side-to-side, excessive sagging when loaded, or abnormal tire wear patterns. Additionally, if your springs have over 500,000 miles or show significant rust and corrosion, it's time to consider replacement. Regular inspections during oil changes can help catch spring issues before they lead to roadside failures or DOT violations.
