BUYAUTOPARTS! A/C Compressor Kit — Chevy Silverado & GMC Sierra 2004–06 6.6L Duramax, Complete Kit w/ 2-Year Warranty

Complete replacement A/C compressor kit engineered to restore reliable air conditioning performance for 2004–2006 Chevy Silverado and GMC Sierra trucks with the 6.6L Duramax diesel.

This BuyAutoParts 60-81579RK kit supplies a brand-new compressor with clutch plus all necessary service components so you can rebuild the vehicle’s MVAC system without hunting parts. Built to ISO/TS 16949 manufacturing standards and backed by a two-year unlimited-mileage warranty, the kit is intended as a direct-fit repair solution for the specified Chevy and GMC models. The package arrives ready to install—no core charge—and includes the filters and seals that commonly require replacement whenever the compressor is serviced.

What parts are included in the A/C kit and why does that matter?

The kit contains a fully assembled compressor with clutch, a receiver-drier (filter), expansion valve, the correct oil, and all necessary O-rings and seals. Replacing these components together reduces contamination risk and prevents repeated failures from leftover debris or degraded seals.

• Compressor with clutch: prefilled with the correct lubricant for MVAC use
• Receiver-drier: removes moisture and particulate from the refrigerant
• Expansion valve: ensures proper refrigerant metering and pressure control
• O-rings and seals: matched sizes to prevent refrigerant leaks

Is this compressor a direct fit for my 6.6L Duramax truck?

Yes—the unit is specified to fit 2004, 2005, and 2006 model-year Chevy Silverado and GMC Sierra trucks equipped with the 6.6L Duramax diesel engine. The kit is manufactured and tested to match factory dimensions and mounting points, simplifying installation and minimizing modification.

• Exact-fit die patterns and mounting holes for the specified models
• Clutch alignment designed for stock pulley and belt setups
• No core return required—new compressor arrives ready to install

How does the warranty and quality control protect my purchase?

This compressor kit is covered by a two-year unlimited-mileage warranty, and production adheres to ISO/TS 16949-quality standards. That combination supports long-term reliability and offers recourse if defects arise from manufacturing or materials within the warranty period.

• 2-year unlimited-mileage warranty from BuyAutoParts!
• ISO/TS 16949 manufacturing oversight and quality checks
• U.S. shipping and warranty support to streamline service

What should I know about installation and refrigerant handling?

Installation is simplified by the kit’s exact-fit design and included consumables, but A/C service requires proper tools and refrigerant recycling equipment. The kit’s components are intended for motor vehicle air conditioner (MVAC) systems; use refrigerant in a 20-ounce self-sealing container and follow EPA and local regulations for charging and disposal.

• Use certified A/C tools and refrigerant recovery machine for safe service
• Charge using a 20-ounce self-sealing container as specified
• Replace receiver-drier when compressor is changed to remove moisture
