Description

Keep your air conditioning system clean and dry with the Four Seasons A/C Receiver Drier 33988, a steel filter drier built to service the high side of the refrigerant loop. It's a direct-fit replacement for a wide range of Class 8 trucks, including the 2012-2024 Freightliner 114SD, 2013-2023 Freightliner 122SD, 2011-2020 Freightliner Cascadia, 2011-2025 Freightliner M2 112, 2012-2023 Western Star 4700SB and 4700SF, and 2010-2021 Western Star 4900EX — see the "Vehicles it fits" section for the full list of applications.

Steel construction: a steel filter drier housing with quality welds for a durable, leak-free design.
Filters and dries: uses a desiccant bag to absorb moisture and remove contaminants that flushing alone cannot clear.
Install hardware included: ships with the necessary gaskets, o-rings, and seal for the job.

The receiver drier acts as a filter, pulling moisture and debris out of the A/C system. A leaking or open system can saturate the desiccant bag within hours, so replacing the drier any time the system is opened or serviced is standard practice — and is typically required to validate compressor warranty. Backed by Four Seasons' decades of mobile A/C experience.

Frequently Asked Questions

What is the A/C receiver drier 33988?

It's a steel filter drier for the air conditioning system that removes moisture and contaminants from the refrigerant using a desiccant bag.

Does it include installation hardware?

Yes. The unit ships with the necessary gaskets, o-rings, and seal for installation, per Four Seasons.

Why should the receiver drier be replaced during A/C service?

Contaminants and moisture can't be cleared by flushing, and an open system can saturate the desiccant within hours, so replacement is recommended any time the system is serviced.

Does replacing it affect the compressor warranty?

Four Seasons states that replacing the accumulator/filter drier is required to validate compressor warranty and must be done anytime the system is serviced.

Will this fit my truck?

It's a direct-fit replacement for many Freightliner and Western Star models from 2008-2025. Check the "Vehicles it fits" section to confirm your exact year and model.
