Frequently Asked Questions About International LT Shock Absorbers

Which shock absorbers fit my specific International LT model year?

International LT shock absorbers vary by model year and configuration. For 2017-2024 International LT models, you'll need to check whether you have the standard suspension or air ride system. Most aftermarket shocks are designed for specific year ranges: 2017-2019, 2020-2022, and 2023-2024 models may have different mounting points and lengths. Always verify your truck's VIN and suspension type before ordering, as day cab and sleeper models often require different shock specifications.

What's the difference between OEM and aftermarket shock absorbers for my International LT?

OEM shocks are built to original factory specifications and typically last 50,000-75,000 miles under normal conditions. Aftermarket options like Bilstein, Gabriel, and Monroe often feature upgraded valving and heavy-duty construction that can extend life to 100,000+ miles. Many aftermarket shocks also offer better heat dissipation and nitrogen charging for consistent performance under heavy loads. The trade-off is usually a firmer ride, though many drivers prefer this for improved handling and stability.

Can I install International LT shocks myself, or do I need special tools?

While shock replacement is possible for experienced DIYers, it requires specific tools including a spring compressor for some models, impact wrenches, and proper jack stands rated for commercial vehicles. The front shocks typically take 1-2 hours per side, while rear shocks can be completed in 30-45 minutes each. Many customers report difficulty with rusted bolts and tight clearances, especially on high-mileage trucks. Professional installation usually runs $200-400 and ensures proper torque specifications are met.

How do I know when my International LT shocks need replacement?

Common signs include excessive bouncing after hitting bumps, nose-diving during braking, uneven tire wear, and visible oil leaks on the shock body. International LT drivers often report a "floating" sensation at highway speeds or increased sway in crosswinds when shocks are worn. Physical inspection should reveal any bent shafts, damaged bushings, or corrosion. Most mechanics recommend replacement every 75,000-100,000 miles as preventive maintenance, or sooner if you frequently haul maximum loads.

Will upgrading my shocks affect my International LT's ride height or require other modifications?

Quality replacement shocks maintain factory ride height when installed correctly. However, some heavy-duty options may provide a slightly firmer ride that gives the impression of sitting higher. No additional modifications are required when using direct-fit replacements. Avoid "lifted" shocks unless you've modified your suspension system, as these can cause premature wear on other components. Air ride equipped trucks must use shocks specifically designed for that system to maintain proper function of the height control valves.
