Outopakkle Rear A/C Line Kit for 2015–2019 Suburban, Yukon XL & Escalade ESV — Direct-Fit Complete Kit

Outopakkle 926-837 is a complete rear auxiliary air conditioning refrigerant line kit designed to replace worn or damaged A/C lines on 2015–2019 Chevrolet Suburban, GMC Yukon XL and Cadillac Escalade ESV models.

When the rear A/C in your full-size SUV starts underperforming or leaks refrigerant, a reliable replacement line assembly restores flow and seals. This Outopakkle kit is a direct-fit aftermarket solution that matches OE routing and connects to existing fittings, offering improved corrosion resistance and the hardware needed for installation.

How does this kit restore rear A/C performance?

The kit replaces cracked, collapsed, or leaking high-side and low-side refrigerant hoses to recover cooling capacity in the rear evaporator. Proper routing and fresh O-rings eliminate leaks and pressure loss so the system can hold refrigerant and operate efficiently.

• Includes both high-side and low-side refrigerant lines for the rear circuit.
• New O-rings and mounting bolts to ensure leak-free connections.
• Direct-fit design for OE attachment points and factory routing.

What materials and build quality are used in the Outopakkle lines?

These hoses use reinforced flexible tubing with corrosion-resistant aluminum fittings to withstand vibration and temperature cycles. The internal reinforcement keeps lines from collapsing under pressure while fittings resist rust in road-exposed areas.

• Reinforced hose core for long-term pressure stability.
• Aluminum fittings to prevent corrosion at connection points.
• Factory-matching lengths and bends for easy installation without modifications.

Which vehicles and part numbers does this kit replace?

The kit is made to fit full-size GM SUVs built 2015–2019 and replaces several OE part numbers for the rear A/C lines. Check compatibility against your VIN, but it is intended for Suburban, Yukon XL and Escalade ESV models in the listed years.

• Compatible models: Cadillac Escalade ESV, Chevrolet Suburban, GMC Yukon XL (2015–2019).
• Replaces OEM numbers including 23443879, 23499086, 84170679, 84524267.
• Comes as a complete assembly to replace the entire rear refrigerant circuit.

What comes in the box and is installation difficult?

The kit ships with all lines, necessary O-rings and mounting bolts so you won’t need to source extra parts during replacement. Installation complexity depends on access to the rear evaporator and may require basic A/C service tools and refrigerant recovery—professional installation is recommended if you lack A/C experience.
