Product Description
TH50521 LaCrosse 2010-2016 Lower Kit with Cut Out for Factory Trim, 8 Pieces
TH50521 is the eight-piece Lower Kit in polished stainless steel for the 2010-2016 Buick LaCrosse sedan. It sits on the doors, spanning from the bottom of the door up, and its bullet says "with Cut Out for factory trim." The width entry needs checking before you order.
Width: read with care
The bullet reads "2.375" - 3 0.75" tapered Width." The width field on the same record shows only 0.75". The first figure, 2.375", is clear. What follows it isn't. We won't pick a number for you. Measure from the bottom of your door to where you'd expect the trim to end, compare with the product photos, and call 877-752-3811 so we can confirm the real width.
The cut out
The record says the kit has a cut out "for factory trim" and doesn't say where it is or what it clears. The product photos are the best guide. If the trim on your doors looks different from what the photos show, call before buying.
On the doors versus below
This is the only one of the three linked LaCrosse side kits that sits on the doors. TH50520 (four pieces, 1.625"-3") and TH50523 (two pieces, 1.25") both install below the door, on the rocker. The record doesn't say whether either is meant to be combined with this kit.
Steel and tape
QAA forms the eight LaCrosse pieces in the USA from polished 26 gauge 304 stainless steel, and they attach over the existing surface with 3M automotive-grade acrylic foam tape. Per QAA, the tape will hold for a lifetime without harming the Buick.

Pillar sets PP50520 and PP50521, the gas door cover GC50520, and wheel well accents WQ50520 ("Cut to fit with Rocker kit sold separately") and WQ50521 ("Full Length") are linked. Check each listing for its finish and ask us about the cut-to-fit pairing.
Arranging eight
No layout comes with the record. Line the pieces up against the photos, note any piece with an opening, and label each liner.
Prep
Wash the lower doors, dry, and finish with isopropyl alcohol.
Install
If a piece has the cut out, fit it first with painter's tape, checking the opening against your doors and the photos. Then position the rest around it. Peel and press each in turn.
Sides
Copy your LaCrosse measurements from one run to the next.
Contact
What to have ready when you call
Your LaCrosse's year, a photo of one full side taken square on, a close-up of the lower doors, and a measurement from the bottom of a door up to any trim there. With those we can check both the width and the cut out against your car.
Equipment
Car soap and a bucket, clean towels, isopropyl alcohol, painter's tape, a tape measure and a marker. Choose a mild, dry day in a garage or shade.
Under the trim
Check the lower doors for chips or lifting paint before cleaning, and fix them first.

Installation tips: Rocker Panel Trim, Lower Kit
- Unpack all 8 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.
