Product Description
Six-Piece Stainless Pillar Trim Kit for the 2017-2023 GMC Acadia SUV (PP57426)
For Acadia owners who want more of the window frame in steel, PP57426 is the larger of the two pillar kits QAA catalogs for the 2017-2023 GMC Acadia. It has six pieces of polished 304 stainless steel, cut to the pillars of the 4-door SUV.
The case for six
The Acadia's sibling kit, PP57425, has four pieces. Two additional pieces in this kit extend the bright finish across more of the pillar area, leaving less of the existing finish showing. QAA's catalog does not state which post each piece fits, so look at both listings' photos to see how far the steel goes. If you want the fuller look in one order, this is the kit to choose.
Fitment
QAA lists this kit for the GMC Acadia 4-door SUV in model years 2017, 2018, 2019, 2020, 2021, 2022, and 2023. No other body style is listed. Match your vehicle to the Fitment tab, which shows the application exactly as cataloged.
What pillar trim is
Pillars are the vertical body sections that frame the side glass and hold up the roof. Pillar trim is a thin cover that goes over them. It replaces nothing and changes no function. What it does change is the look: a dark, blended window line becomes a series of crisp, bright openings.
Material and finish
All six pieces are made in the USA from 26-gauge 304 stainless steel, polished to a mirror shine. Because there is no plating, the finish is part of the steel itself. The six pieces match each other exactly.
Installation
On the Acadia, the six covers stick to the existing pillars using 3M automotive-grade acrylic foam tape, and you will not take off any trim. According to QAA, the tape holds for a lifetime without harming the GMC's surface.
Start with clean, dry pillars. Lay the six pieces out by position and test-fit each one before you peel the backing. Dry-fit each Acadia cover and compare it with the photos before any liner comes off. A soft cloth wipe at the end takes care of fingerprints on the polished steel. The Installation tab lists the steps in order.
Also for the Acadia
QAA catalogs a 2-piece mirror cover replacement set (MC57425) for this SUV, noted as top only and for mirrors with no turn signal. Check your mirrors before ordering it.
Choosing between the two kits
Check the other Acadia pillar kit's listing for its finish; this sheet covers only this one. The only difference is coverage. If you want a subtle accent, the four-piece kit does that. If you want the window frame more fully finished, choose this six-piece set.

Part number PP57426 has UPC 691821592753. Both are on the Specs tab along with the material and piece count. For help, call Quality Automotive Trims at 877-752-3811.
Paint color plays a part in the final effect. On a dark Acadia, six polished pieces stand out strongly against the paint and glass. On a lighter color, they read more like a refined factory accent.

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.
