4th Gen Ram Complete Repair Kit (09-19) Single Zone only – Blend Door USA

Your heat works sometimes. Your A/C cuts out. The temperature swings on its own. On 4th Gen Ram trucks, the plastic HVAC doors are the root cause — they crack, warp, and fail over time. This kit replaces all of them permanently with solid CNC-machined aluminum.

Kit Includes:

• aluminum Blend Door
• aluminum Mode 1 Door
• aluminum Mode 2 Door
• Aluminum bracket to repair the original Recirculation Door

All parts manufactured in Michigan. Lifetime guarantee on everything we produce.

Fits (Single Zone):

• 2009–2018 Ram 1500
• 2010–2019 Ram 2500, 3500, 4500

Single Zone vs. Dual Zone — which do you have?
Single Zone trucks control driver and passenger temperature together from one dial.

 Dual Zone is a factory upgrade that allows independent driver/passenger temperature control. You cannot upgrade from Single to Dual Zone by swapping doors — the HVAC box is different. If you have rear vents, the only difference between kits is the ductwork, not the doors.

Why replace it?

• Inconsistent heat or A/C that comes and goes
• Temperature stuck or drifting without input
• Clicking or grinding from behind the dash
• Previous plastic door repair that failed again

OEM plastic fails. Aluminum doesn’t. One repair, done for life.
