This replacement discharge (high-pressure) line is designed to match factory specifications for many Chevrolet, GMC and Cadillac full-size trucks and SUVs from the mid-2000s through the mid-2010s. Built to withstand system pressure, vibration and heat under the hood, the assembly includes factory-style fittings and exact-length routing so installers can replace a failed or leaking hose without modification. Part numbers cross-referenced include common OEM references to help confirm compatibility.

Which vehicles will this A-Premium discharge hose fit?

Compatibility covers a wide range of GM models and engine combinations. It fits multiple model years of Chevrolet Tahoe, Suburban, Avalanche; GMC Sierra, Sierra Classic and Yukon; and select Cadillac applications where the same OEM hose was used. Check engine code, VIN details and rear temperature control (RTC) options to ensure a proper match.

• Chevrolet Tahoe/Suburban/Avalanche models (2006–2014) with listed engine codes and RTC configurations
• GMC Sierra 1500 and Sierra Classic variants across V6 and V8 engines (2006–2013)

How does this hose match OEM performance and installation needs?

The assembly is manufactured to mirror original routing, fittings and length so it installs like the factory part. Materials and crimps are selected to resist refrigerant leaks, oil exposure and under-hood heat. That reduces installation time and avoids the common pitfalls of generic hoses that require adjustments.

• Factory-style fittings and mounting points for bolt-on installation
• High-pressure-rated tubing and durable protective coverings
• Designed for direct replacement—no cutting, flaring or custom modification

What are the technical details and part references I should confirm?

Before ordering, verify your vehicle year, engine displacement, VIN engine code and whether rear temperature control (RTC) is present. The product lists several OEM cross-reference numbers to make matching easier. Use these references alongside your vehicle’s service manual or parts sticker to ensure compatibility.
