Product Description
Buick LaCrosse Sedan Pillar Post Trim, 4 Stainless Pieces, 2017-2019 (PP57520)
The Buick LaCrosse 4-door sedan is listed in QAA's catalog for 2017, 2018, and 2019, and three pillar post kits are cut for it. PP57520 is the four-piece version, the most compact of the three. It finishes the pillars between the side windows in polished stainless steel and leaves the rest of the car's styling as it is.
Three LaCrosse kits
QAA's LaCrosse pillar lineup is PP57520 with four pieces, PP57521 with six, and PP57522 with eight. Only the eight-piece kit carries a coverage note: it includes the front triangles. The four- and six-piece kits have no such note, and the catalog does not describe which post each of their pieces covers. Comparing the photos on each listing is the easiest way to see the difference. If you do not need the front triangles and want a restrained accent, four pieces is the place to start.
Why pillar trim works on a sedan
Pillars are the upright sections of the body that frame the windows and carry the roof. On the LaCrosse sedan, the pillars sit between and beside the side windows. Bare, they are easy to overlook. Polished steel over the pillars divides it into framed openings and gives the side of the car a more finished look.
Material
QAA makes these four pieces in the USA from 26-gauge 304 stainless steel, polished to a mirror shine. Because the material is solid stainless, the shine belongs to the metal and is not a plated surface that could lift.
Installation
Each piece mounts with 3M automotive-grade acrylic foam tape and installs directly over the existing pillar surface. There is nothing to remove. QAA states the tape will hold for a lifetime without causing damage to the vehicle surface. Wash and dry the pillars, wipe off any wax, test-fit every piece, and then peel and press one at a time. The Installation tab lays out the steps.
With only four pieces, this is the quickest of the three LaCrosse kits to put on, which makes it a good first project for owners who have not installed tape-on trim before.
Fitment
Listed for the Buick LaCrosse 4-door sedan, model years 2017 through 2019. The Fitment tab shows the application exactly as QAA catalogs it. Other years and body styles are not listed for this kit.
Deciding on coverage
Every LaCrosse kit is a complete set on its own, so it is worth deciding how much steel you want before ordering. If the front triangles matter to you, look at PP57522. If you simply want the main pillars brightened, this kit or the six-piece PP57521 will do it.

A finishing tip: polished steel shows fingerprints, so give each piece a gentle wipe with a soft cloth once the tape has been pressed down along its full length.

Installation tips: Pillar Post Trim
- Unpack all 4 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.
