Keystone CH1390115 Front Door Opening Weatherstrip Seal RH=LH Standard Cab Ram 1500 2500 3500

The Keystone CH1390115 is an OEM-replacement front door opening weatherstrip designed for full-size Ram pickup trucks. Mounted on the body at the door opening, this seal creates a weather-tight barrier between the door and the cab, blocking wind, water, dust, and road noise from entering the cabin. It replaces OEM Mopar part number 55369282AB.

This weatherstrip installs on both the right-hand and left-hand door openings (RH=LH), making a single part number applicable to either side of the vehicle. It is designed specifically for Standard Cab configurations and includes coverage for the 2019–2023 Ram 1500 Classic in addition to the broader 2009–2024 Ram full-size pickup truck lineup.

Key Features:

• Direct OEM-style replacement for Mopar 55369282AB
• Mounts on the body at the front door opening (not on the door itself)
• RH=LH fitment — one part fits both driver and passenger sides
• Includes integrated strip for a complete, secure seal
• Designed for Standard Cab body style
• Compatible with 2019–2023 Ram 1500 Classic
• Restores factory-quality noise, water, and dust protection
• Precision-molded to match original equipment geometry for easy installation

Over time, door weatherstrips can harden, crack, or compress permanently, leading to wind noise, water leaks, and reduced cabin comfort. Replacing a worn seal with the Keystone CH1390115 restores the factory fit and function at an OEM-comparable quality level.
