jasperautopart Aluminum Rear A/C Block Kit for 2014–2019 Chevrolet/GMC/Yukon/Tahoe — 6061 Billet, Sealed Repair

jasperautopart Aluminum Rear A/C Block Kit lets you safely disable a faulty rear air-conditioning circuit without replacing the vehicle's rear evaporator or expensive factory lines.

If the rear A/C on your 2014–2019 Chevrolet Suburban, GMC Suburban 1500/2500, Yukon Denali XL, Tahoe, or Cadillac Escalade has failed, this CNC-machined 6061 billet aluminum block kit provides a durable, sealed solution that preserves the front system and saves on repair costs. The kit is designed to be installed in the engine compartment after disconnecting the rear lines so the vehicle can continue to run the front A/C normally. Built for corrosion resistance and high-heat environments, the kit includes a sealing washer and organize tape to help ensure a leak-free connection.

How does the block kit keep my front air conditioning working?

By isolating the rear A/C lines and creating a reliable sealed termination, the block kit prevents refrigerant leakage while allowing the front compressor, condenser and evaporator to operate independently. That means you do not need to replace the entire rear evaporator or extended pipeline to restore usable cabin cooling up front.

• Seals rear low- and high-pressure lines in the engine bay.
• Maintains refrigerant charge and front-system pressure balance.
• Prevents cross-contamination between rear and front circuits.

Is installation something I can do myself?

Installation is straightforward for anyone comfortable with basic automotive work: disconnect the rear A/C lines, install the billet aluminum block in the engine compartment, and confirm a secure seal. No specialty tools are required beyond common hand tools, and the included high-quality washer and sealing tape help simplify the process.

• Simple disconnect and replace procedure—no cutting or splicing.
• Fits factory connection points for models listed.
• Comes with organized tape and a sealing washer for reliable fitment.

What materials and durability features protect this kit over time?

The block is CNC machined from 6061 billet aluminum alloy, chosen for its strength, thermal tolerance, and corrosion resistance. The construction stands up to engine-bay heat and road conditions, and the included sealing washer is sized to deliver 100% sealing protection when installed correctly.

• 6061 billet aluminum resists corrosion and deformation.
• High-heat tolerance suitable for engine compartment use.
• Durable washers and organized tape reduce leak risk long-term.

Which models and years are compatible with this block kit?

This block kit is made specifically for later model GM SUVs and trucks where the rear A/C plumbing is separate from the front system. Confirm fit for your vehicle by year and model before purchase to ensure proper connector type and routing match.
