Product Description
2016-2020 Cadillac CT6 Six-Piece Stainless Steel Pillar Trim (PP56231)
PP56231 is the fuller of QAA's two pillar post kits for the Cadillac CT6. Six pieces of polished stainless steel cover more of the window frame than the four-piece PP56230, and the kit is listed for the 4-door CT6 sedan in every model year from 2016 to 2020.
Why owners choose six
A sedan's side carries a fair amount of pillar area. With six pieces, more of that area ends up in polished steel and less of the original black remains. QAA's data identifies the two CT6 kits by piece count only; it does not say which post each piece fits. The listing photos are the best way to see what the two further pieces cover. If you want the most complete frame QAA offers for this sedan, this is it.
What pillar trim is
Pillars are the vertical body sections between and beside the windows that support the roof. Pillar trim is a thin cover that sits over them. It does not replace anything; it changes the finish from a dark surface to a bright one. On a luxury sedan like the CT6, that bright outline around the glass gives a crisp, tailored detail.
304 stainless, made in the USA
Each of the six pieces is made in the USA from 26-gauge 304 stainless steel. QAA polishes it to a mirror shine. Since the material is solid stainless, there is no plated coating to peel away, and all six pieces share the same color and brightness.
How it attaches
The pieces use 3M automotive-grade acrylic foam tape and install directly over the existing pillar surface. No trim removal. QAA states the tape will hold for a lifetime without causing damage to the surface of the vehicle. Start with a clean, dry surface in a shaded spot, sort the six pieces by position, and test-fit before peeling. Press each CT6 cover only after the dry fit shows an even gap at the glass. The Installation tab spells out the steps.
Matching CT6 trim
If you plan to go further, QAA lists more parts for the 2016-2020 CT6. There is TH56230, an 8-piece lower rocker panel kit spanning 3.125 to 3.875 inches up from the bottom of the door. WQ56231 is a 6-piece wheel well accent cut full length, with the rear trim pieces segmented into two. WQ56230 is a 4-piece wheel well set cut to fit alongside the rocker kit. GC56230 is a gas door cover, and RW56230 is a rear window trim with a parallel span to the top edge.
Fitment
The listed application is the Cadillac CT6 4-door sedan for 2016, 2017, 2018, 2019, and 2020. The Fitment tab shows it exactly as cataloged.

Installation tips: Pillar Post Trim
- Unpack all 6 pieces and match each one to its position on the vehicle, using the product photos, before fitting any of them.
- Each piece mounts with 3M automotive-grade acrylic foam tape, so clean and dry the mounting surface first; the tape needs paint or trim free of dirt and wax.
- Align the piece and press it firmly into place directly over the existing surface, working along its full length so the tape bonds evenly.
- Fit one piece at a time and compare each with the product photos and the pieces already in place.
These are general tips. Follow any instructions packed with your kit if they differ.
