International RH DPF & Mufflers

Frequently Asked Questions About International RH DPF & Mufflers

What does "RH" mean in this category, and how do I know it's the right side for my truck?

RH refers to the right-hand side mounting configuration of the DPF (Diesel Particulate Filter) and muffler assembly as installed on the truck frame. International trucks can be equipped with either left-hand or right-hand exhaust configurations depending on the model year and chassis setup, so it's important to confirm your truck's specific configuration before ordering. Checking your existing unit's mounting position or referencing your VIN and chassis specs is the most reliable way to confirm fitment.

Will this DPF and muffler assembly fit my specific International model and year?

Fitment can vary significantly between International models such as the ProStar, LT, and older 9900i or 4000 series, as well as by engine and emissions system year. We recommend verifying part numbers against your truck's OEM specifications or providing your VIN when ordering to ensure the unit matches your exhaust routing, mounting brackets, and emissions system requirements.

Are these units new, used, or reconditioned, and does that affect performance?

Our inventory includes a mix of new aftermarket, used take-off, and reconditioned DPF and muffler assemblies. Used and take-off units are inspected for structural integrity and functional condition before listing, but they may show normal wear consistent with their service life. If your truck relies on the DPF for emissions compliance, a used unit's soot loading and filter condition should be considered before purchase.

Do I need to worry about emissions compliance when replacing a DPF assembly?

Yes. The DPF is a core component of your truck's emissions control system, and replacing it with a non-functioning, clogged, or incompatible unit can trigger fault codes or cause the truck to fail emissions inspections. If you're purchasing a used DPF, it's a good idea to have it professionally inspected or cleaned before installation to confirm it will perform correctly with your truck's aftertreatment system.

What should I check before installing a replacement DPF and muffler unit?

Before installation, inspect all mounting brackets, clamps, and gaskets for wear or damage, and confirm that the inlet and outlet connections align with your truck's existing exhaust piping. It's also wise to check for any related sensors, such as temperature or pressure sensors, that may need to be transferred or replaced. Because this is an emissions-related component, installation should be performed by someone familiar with diesel exhaust and aftertreatment systems.
