A-Premium A/C Discharge Line Hose Assembly for Cadillac & GM Trucks SUVs — Direct-Fit, High-Pressure Replacement (2006–2014)

The A-Premium A/C Discharge Line Hose Assembly is a high-pressure refrigerant line that connects the compressor to the condenser, engineered to restore proper air-conditioning flow for select GM and Cadillac trucks and SUVs.

This durable replacement hose is designed to match OE fit and function for many Chevrolet, GMC and Cadillac models from the mid-2000s through the mid-2010s. Constructed to withstand high pressure and heat, it arrives ready to install where the factory discharge line has worn, cracked, or begun to leak. If your vehicle shows reduced cooling, hissing from the A/C bay, or visible hose damage, this assembly provides a direct-fit option backed by a one-year unlimited-mileage warranty.

Which vehicles will this discharge line fit?

This hose covers a broad list of GM platforms, including multiple Tahoe, Suburban, Avalanche, Sierra and Yukon model years. Fit varies by engine type, rear temperature control (RTC) equipment, and specific VIN/engine codes—always verify compatibility with your vehicle’s engine code or parts reference numbers before ordering.

• Chevrolet Tahoe/Suburban and Avalanche models from roughly 2006–2014 with specified V6/V8 engines and RTC options.
• GMC Sierra 1500 and Sierra Classic spanning 2006–2013 across 4.3L, 4.8L, 5.3L, 6.0L and 6.2L engines with noted VIN/engine code conditions.
• GMC Yukon model years 2006–2014 for many 4.8L and 5.3L/6.0L configurations without RTC in select years.
• Cross-reference reference numbers: HA111392C, 22759498, 22876350, 25940202 and others to confirm match.

How does this hose perform compared to the original part?

The assembly is engineered for high-pressure refrigerant routing and built with reinforced materials to resist heat, vibration and corrosion where factory lines commonly fail. It aims to provide the same routing and connection points as OEM parts, simplifying swap-in replacement.

• High-pressure construction suitable for compressor-to-condenser service.
• Factory-style fittings and mounting points for direct fit on compatible models.
• Corrosion-resistant finishes to extend service life in under-hood conditions.
• Manufactured to meet common OE dimension and pressure expectations.

What should I check before buying and installing this line?

Confirm vehicle compatibility by year, engine displacement, engine code or VIN details and whether rear temperature controls are present; incorrect match can prevent proper installation. Also inspect connecting O-rings and related A/C components—replacing old seals at the same time reduces the chance of leaks after installation.

• Verify engine code or VIN and match to listed vehicle fitment ranges.
• Replace O-rings and seals when installing to ensure leak-free joints.
• Have a qualified technician evacuate and recharge refrigerant per regulations.
• Compare reference numbers (e.g., HA111392C, 34-64290) to OEM part catalogs where possible.

Is there a warranty or guarantee with the A-Premium hose?

A-Premium provides a one-year unlimited-mileage warranty on this A/C hose assembly, covering manufacturing defects under normal use. The warranty gives confidence for buyers replacing worn or damaged discharge lines, but it does not replace professional installation or routine maintenance responsibilities.

• One-year unlimited-mileage limited warranty from A-Premium.
• Warranty covers manufacturing defects, not installation errors or improper service.
• Keep purchase and installation records to support any warranty claims.

Who is this for: Technically minded DIYers and professional mechanics working on mid-2000s to mid-2010s Chevrolet, GMC or Cadillac full-size trucks and SUVs who need a reliable compressor-to-condenser high-pressure line. Ideal when the original discharge hose shows leaks, cracking, or has failed, and when a direct-fit replacement with OEM-style connections and a manufacturer warranty is required.
