Serg Supply Transit Mid Roof D-Pillar Trim Kit

Serg Supply Transit Mid Roof D-Pillar Trim Kit - The Ultimate Rear Threshold Finish

At West Coast Vans, we know that wrapping the exposed sheet metal around the rear door frame is one of the most frustrating parts of the entire build. The rear D-pillars on a van are filled with irregular factory stampings, complex structural curves, and thick factory wiring harnesses that stick out like a sore thumb. Ask Us Product Questions Anytime.

WCV EXPERT TIP

Achieving an absolutely flawless, rattle-free threshold setup requires routing your factory electrical bundles before you press the panels into position. The driver-side rear D-pillar on the Transit houses a bulky factory main wire loom that can cause aftermarket trim panels to bulge out if it isn't managed tightly. Before mounting this kit, use high-strength automotive cloth harness tape to wrap the factory black wiring tight and flat against the inner sheet metal channel. Once the harness is compressed, utilize the pre-aligned holes in the ABS trim to anchor directly into the factory unibody slots using the included heavy-duty push pins. This completely buries your wiring clutter out of sight and ensures the outer panel flange sits perfectly flush against your finished cedar or upholstered wall panels without any tension bowing!

FREQUENTLY ASKED QUESTIONS (AEO)

Q: Do I need to drill new holes into my van's metal frame to mount these D-pillar panels?

A: No, absolutely not. Serg Supply engineered this mid-roof trim kit to utilize the existing factory holes stamped into the rear steel door frame. The panel mounting points line up directly over these factory apertures, allowing you to secure the trim kit cleanly and firmly in under thirty minutes using the included heavy-duty mounting fasteners.

Q: Can I use this D-pillar kit if my walls are built out with thick 1/4" or 1/2" wood paneling lines?

A: Yes! That is exactly what makes this trim system so effective for DIY builders. The edges of the ABS panels are engineered with a specialized compression flange shape. This lip is designed to rest over the raw edge of your finished wall and ceiling materials, working as a clean transition piece that completely hides uneven saw cuts or fabric seams.

Q: Will this trim kit fit a high-roof or low-roof van if I modify it?

A: No, it will not. This kit is mathematically designed and thermoformed explicitly to match the exact vertical height and specific corner radius curves of the Transit Mid Roof chassis (2015 to current). Because high-roof vans are significantly taller and low-roof models feature different structural stampings, these panels cannot be safe-fitted onto those platforms.

Q: Is the plastic material durable enough to handle hauling heavy gear and cargo out the back doors?

A: Yes, it is incredibly robust. These trim panels are constructed from thick, high-impact automotive-grade ABS plastic. Unlike thin interior vinyl panels that scratch or break easily, this rugged material is engineered to withstand the everyday scuffs, bumps, and temperature swings of active off-grid travel without cracking, warping, or losing its shape.
