A-Premium A/C Discharge Line Hose Assembly for Dodge Ram 2004–2007 — High-Pressure, OEM-Style Fitment

A-Premium A/C discharge line hose assembly replaces the high-pressure compressor-to-condenser line for select Dodge Ram models, restoring reliable air conditioning flow and system integrity.

If your Dodge Ram's air conditioning has weak cooling, visible refrigerant oil, or a failed high-pressure line, this A-Premium discharge hose is built to fit and perform. Designed to match factory routing and connections for multiple 2004–2007 Ram configurations, the hose connects the compressor outlet to the condenser and is intended for high-pressure service on V6 and V8 engines listed below.

Which Dodge Ram models and engines does this hose fit?

This discharge line is manufactured to be compatible with specific Ram trucks from the mid-2000s. Confirm the part reference or your vehicle’s model year and engine size before ordering to ensure a direct replacement.

• Ram 2500 2004 V8 5.7L (4-door)
• Ram 3500 2004 V8 5.7L and 2005 V8 5.7L (part number 55057045AB)
• Ram 1500 2004–2007 V6 3.7L and V8 4.7L
• Service position: discharge/high-pressure line from compressor to condenser

What construction and durability features does the A-Premium hose offer?

The hose uses a four-layer architecture to resist wear, collapse and temperature extremes that commonly stress A/C lines. These materials and assembly choices are intended to extend service life and maintain consistent high-pressure refrigerant flow under load.

• Four-layer hose body for enhanced flex and crush resistance
• Wider operational temperature range to handle hot engine bays
• Factory-style fittings and crimps to match OEM connections
• Designed to resist external abrasion and internal collapse

How does installing this hose restore my vehicle’s HVAC performance?

Replacing a leaking or damaged high-pressure discharge line removes refrigerant loss and pressure instability that reduce cooling capacity. A properly sealed, correctly routed hose helps the compressor and condenser operate within designed pressure ranges, improving comfort and system reliability.

• Stops refrigerant leaks at the compressor-to-condenser junction
• Re-establishes correct system pressure for effective heat exchange
• Helps prevent compressor damage due to low refrigerant or contamination
• Fits OEM routing to avoid kinks and chafing against chassis parts

What reference numbers and warranty come with this replacement line?

The part aligns with several common reference numbers used by technicians and parts sellers to confirm compatibility. A-Premium backs the hose with a one-year unlimited-mileage guarantee for added confidence after installation.

• Reference numbers: HA111801C, HA 111801C, 34-63884, 3463884, 4811888, 55167
• Cross-references: 55057045AA, 55057045AB, 55057045AC
• Warranty: one-year unlimited-mileage on manufacturing defects
• Quality control: engineered to meet common aftermarket fit standards

Who is this for: Technicians, DIY enthusiasts, and fleet maintenance managers who own or service 2004–2007 Dodge Ram 1500, 2500, and 3500 trucks with the listed engines and need a durable, direct-fit high-pressure discharge hose.
