The GoCode Overland ProMaster Rear Trim Kit (GCP0309) from Nomadic Supply Company® is a 3-piece kit that covers the rear D-Pillar interior areas of the Dodge Ram ProMaster in a clean, factory-finished look engineered to match the GoCode B-Pillar and C-Pillar trim lines. Without proper rear trim, the D-Pillar transition zones in a ProMaster build are some of the hardest areas to finish cleanly — the GCP0309 solves that with a precision drop-in kit.
The GoCode Overland ProMaster Rear Trim Kit (GCP0309) is flanged to receive finished wall and ceiling materials — paint, upholstery, or raw ABS — and designed to align precisely with the rest of the GoCode ProMaster trim ecosystem. At 15 lbs for the 3-piece set, it ships as a cohesive kit ready to complete the rear of your build. Pair with GCP0310 (Front Trim Kit) for complete front and rear coverage, or order GCP0391 (Full Interior Trim Kit) for everything in one bundle. Made in the USA by GoCode Overland.
