GDUKOP A/C Evaporator Core for Ram 1500/2500/3500 Replaces 68138270AA/AB — Aluminum Direct-Fit

GDUKOP A/C Evaporator Core replaces OE 68138270AA and 68138270AB to restore reliable air conditioning performance in compatible Ram trucks.

If your truck's cabin temperature control has become sluggish or the air conditioner blows warm air, the evaporator core is a common wear item that affects cooling efficiency. This GDUKOP unit is engineered to match the original fit and function of the factory component used on many Ram 1500, 1500 Classic, 2500, 3500, 4500 and 5500 model years. Built from premium aluminum, it focuses on efficient heat transfer and corrosion resistance so the system can deliver consistent airflow and temperature regulation when installed correctly.

Which Ram models and years does this evaporator fit?

This evaporator core is designed for a range of Ram pickup trucks—verify your vehicle's OE number to confirm compatibility before ordering. It covers multiple model years for 1500, 1500 Classic, 2500, 3500, 4500 and 5500 trucks where the listed part numbers apply.

• Fits Ram 1500: 2012–2019 and 1500 Classic: 2019–2022
• Fits Ram 2500 and 3500: 2012–2018
• Fits Ram 4500 and 5500: 2012–2016
• Always check OE numbers 68138270AA / 68138270AB or EV939965PFC before purchase

How does this replacement improve A/C performance?

The evaporator is where refrigerant absorbs heat from cabin air; a properly functioning core supports stronger cooling and more consistent airflow. Replacing a corroded or internally fouled evaporator restores the system’s ability to exchange heat, which can reduce compressor load and improve overall comfort.

• Aluminum alloy construction for faster thermal transfer
• Corrosion-resistant surfaces to prolong service life
• Dimensional match to original part for correct airflow path
• Helps re-establish proper refrigerant flow and temperature drop

Does this part match original equipment numbers and fitment?

Yes—this GDUKOP evaporator is engineered to replace the factory items indicated by the listed OE and aftermarket reference numbers. It’s produced to align with the same mounting points and core dimensions so technicians can install it without modifying HVAC housings.

• Replaces OE: 68138270AA, 68138270AB
• Also referenced as EV939965PFC / EV-939965PFC
• Manufactured to match original fit, form, and function
• Recommended to verify part number against your vehicle before ordering

What should I know before installation?

Installation requires discharging and evacuating the A/C system by a qualified technician, followed by leak testing and proper refrigerant recharge. Because the evaporator sits inside the HVAC housing, plan for labor time and inspect related components—dryer/accumulator, expansion valve/orifice tube, and cabin air pathways—while replacing the core.

• Professional A/C service recommended for system evacuation and recharge
• Inspect and replace associated components if contaminated or worn
• Ensure correct refrigerant oil and charge after installation
• Verify airflow and temperature performance post-repair

Who is this for: This GDUKOP evaporator core is intended for owners, fleet managers, and technicians working on compatible Ram 1500, 1500 Classic, 2500, 3500, 4500 and 5500 trucks that require an OE-number-matching replacement. Choose this part when you need a direct-fit aluminum evaporator that mirrors original factory specifications and helps restore your truck’s air conditioning efficiency—just confirm the OE number before purchase to ensure exact compatibility.
