Frequently Asked Questions About International 9900/i/ix Shock Absorbers

Will these shock absorbers fit my specific International 9900 model year?

Our shock absorbers are designed to fit International 9900, 9900i, and 9900ix models from 1987 through 2017. However, there are variations between early models (1987-2003) and later models (2004-2017) due to suspension design changes. Always check the product specifications for your exact year and verify whether you have air ride or spring suspension, as this affects shock mounting points and lengths.

What's the difference between standard and heavy-duty shock absorbers for my 9900?

Standard shocks work well for typical highway driving and moderate loads. Heavy-duty shocks feature larger pistons, stronger seals, and nitrogen charging to handle consistent heavy loads, rough roads, and frequent stop-and-go driving. If you regularly haul maximum weight loads or drive on poor road conditions, heavy-duty shocks will provide better stability and last 30-40% longer than standard options.

Can I install these shock absorbers myself, or do I need special tools?

Installation typically requires basic hand tools including wrenches, sockets, and a jack or lift to support the truck. Most drivers can complete the job in 2-3 hours per axle. The main challenges include accessing upper mounting bolts on some models and properly torquing to manufacturer specifications (usually 125-150 ft-lbs). No special tools are required, but having a helper makes the job easier and safer.

How do I know when my International 9900 shocks need replacement?

Common signs include excessive bouncing after hitting bumps, nose-diving during braking, visible oil leaks on the shock body, uneven tire wear, and increased body roll in turns. Most shocks last 100,000-150,000 miles under normal conditions. If your truck feels unstable or you notice any of these symptoms, inspect your shocks immediately as worn units can affect braking distance and load stability.

What brands offer the best reliability and warranty for International 9900 shocks?

Gabriel, Monroe, and Bilstein are the most trusted brands for International 9900 applications. Gabriel offers excellent OEM-quality replacements with a lifetime warranty. Monroe provides good value with their Gas-Magnum series. Bilstein shocks cost more but deliver superior performance for heavy-duty applications. All three brands offer warranties ranging from limited lifetime to 3 years, depending on the specific model.
