Frequently Asked Questions About International 8600 TranStar Air Springs-Valves

Will these air springs fit my specific year International 8600 TranStar?

Our air springs and leveling valves are designed to fit International 8600 TranStar models from 2007-2017. However, there can be variations based on suspension configurations (Hendrickson, Neway, or International). Before ordering, check your existing part numbers or contact our support team with your VIN to ensure proper fitment. Most fitment issues occur when customers have aftermarket suspension modifications or special vocational configurations.

How difficult is it to install these air springs, and what tools do I need?

Installation typically takes 2-4 hours per axle for someone with moderate mechanical experience. You'll need basic hand tools, jack stands rated for commercial trucks, and an air compressor to test the system. The most challenging part is usually removing the old air springs if they're seized or corroded. We recommend having new air fittings on hand, as the old ones often break during removal. Professional installation runs $200-400 if you prefer not to do it yourself.

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

OEM air springs typically last 5-7 years and cost 40-60% more than quality aftermarket options. Our aftermarket springs use reinforced rubber compounds and meet or exceed OEM specifications. The main differences are price and warranty length - aftermarket usually offers 1-2 year warranties versus 3 years for OEM. Both perform identically when properly installed. Many owner-operators choose aftermarket for cost savings without sacrificing reliability.

How do I know if I need to replace just the air spring or the leveling valve too?

If your truck leans to one side or won't maintain ride height, start by checking for air leaks at the springs using soapy water. A torn or leaking air spring needs immediate replacement. If the springs hold air but the truck still sags or rides rough, your leveling valve likely needs replacement. Common valve symptoms include slow height adjustment, bouncing after hitting bumps, or constant air release sounds. We recommend replacing both components together if your system is over 5 years old to avoid repeat labor costs.

Are there different styles of air springs for different suspension setups?

Yes, the International 8600 TranStar uses three main air spring styles depending on your suspension type. Rolling lobe style (most common) fits standard Hendrickson suspensions. Convoluted bellows style works with Neway AR2 suspensions. Reversible sleeve type fits International's own IROS suspension. Each style has specific mounting dimensions and air volume requirements. Using the wrong style will cause premature failure and poor ride quality. Always match your replacement springs to your existing suspension type.
