Bzsunway Rear AC Line Set for 2015–2020 Tahoe Yukon Escalade — Direct-Fit Reinforced Rubber Replacement (YSH34913)

Bzsunway Rear AC Line Set YSH34913 is a direct-fit auxiliary air-conditioning hose kit that replaces corroded aluminum rear lines on 2015–2020 Chevrolet Tahoe, GMC Yukon, and Cadillac Escalade models.

If your vehicle's rear air-conditioning has weakened or leaked because of brittle factory aluminum tubing, this replacement line set restores flow and reliability without the expense and complexity of replacing original hard lines. Built with reinforced rubber and metal fittings, the kit is engineered to resist corrosion and flexing while matching OEM connection points for straightforward installation.

How does this rear AC line set improve system durability?

The kit replaces original aluminum sections with reinforced rubber and durable metal connectors that tolerate vibration and road contaminants better than thin aluminum tubing. That reduces the typical fracture and corrosion failures common in these models’ factory lines.

• Reinforced rubber hose resists cracking from heat and movement
• Copper/steel fittings reduce corrosion at connections
• Robust materials lower the chance of future refrigerant leaks

What vehicles and years does this kit fit?

This replacement set is made to match the rear auxiliary AC plumbing for full-size GM SUVs from the 2015 through 2020 model years. It is designed as a direct-fit service part to the original service ports.

• Fits 2015–2020 Chevrolet Tahoe rear AC lines
• Compatible with 2015–2020 GMC Yukon rear AC plumbing
• Made for 2015–2020 Cadillac Escalade rear auxiliary AC connections

How easy is installation compared with factory aluminum tubing?

The Bzsunway set uses direct-fit block fittings so you don’t have to cut or remove lengthy factory hard lines, making replacement faster and less invasive. Typical installation requires common hand tools and basic AC service knowledge for safe reconnection and leak testing.

• Direct fit block fittings align with OEM ports for quicker hookup
• No need to remove long factory aluminum runs in most cases
• Simpler than welding or bending original metal tubing

What are the core functional benefits I can expect?

Beyond preventing leaks, the kit restores rear evaporator refrigerant flow so your rear air system can provide intended cooling performance. The metal-reinforced ends maintain secure seals under pressure and temperature cycling.

• Reliable sealing at service ports under operating pressure
• Improved resistance to road salts and corrosion
• Longer service life compared with brittle factory aluminum sections
