Frequently Asked Questions About International LoneStar Shock Absorbers

What years and models of International LoneStar trucks are these shock absorbers compatible with?

Our shock absorbers are designed to fit International LoneStar models from 2009 through 2020. This includes all trim levels and engine configurations. However, trucks with aftermarket lift kits or suspension modifications may require different specifications. We recommend checking your VIN or calling our tech support at 1-888-875-7787 to confirm exact fitment for your specific truck.

Are these OEM replacements or aftermarket upgrades, and what's the difference in quality?

We carry both OEM-equivalent replacements and performance aftermarket options. OEM-style shocks match factory specifications and typically last 50,000-75,000 miles under normal conditions. Our aftermarket performance shocks feature upgraded valving, heavy-duty construction, and nitrogen charging for improved ride quality and longevity - often lasting 100,000+ miles. Popular upgrades include Bilstein, Gabriel, and Monroe brands which offer better heat dissipation and consistent damping under heavy loads.

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

Installation typically takes 2-3 hours for someone with basic mechanical skills. You'll need a floor jack, jack stands, 18mm and 21mm sockets, torque wrench, and penetrating oil for rusty bolts. The front shocks require wheel removal and can be accessed from the wheel well. Rear shocks may require crawling under the truck. Common challenges include seized mounting bolts and compressed springs - having a spring compressor on hand is recommended for safety. Many customers report the upper mounting nuts can be difficult to reach without extensions.

What's the difference between monotube and twin-tube designs for LoneStar applications?

Monotube shocks offer superior heat dissipation and consistent performance under heavy loads or frequent braking, making them ideal for mountain driving or heavy hauling. They typically cost 20-30% more but last longer. Twin-tube designs are more affordable and work well for highway driving and moderate loads. For LoneStar trucks regularly hauling 40,000+ pounds or operating in extreme temperatures, we recommend monotube designs. Both styles are available in our inventory with various compression and rebound settings.

Do these shock absorbers come with a warranty, and what does it cover?

Most shock absorbers we carry include manufacturer warranties ranging from 1 year/unlimited miles to limited lifetime coverage. The warranty typically covers defects in materials and workmanship but excludes normal wear, improper installation, or damage from accidents. Bilstein offers a limited lifetime warranty, Monroe provides 3 years/unlimited miles, and Gabriel covers their heavy-duty line for 1 year. Keep your receipt and register your purchase with the manufacturer for fastest warranty service. Labor costs are generally not covered under these warranties.
