Product Description
Buick LaCrosse 2010-2016 Rocker Trim, 4 Pieces, 1.625"-3" Tapered, Below the Door (TH50520)
TH50520 is a four-piece set of polished stainless steel for the 2010-2016 Buick LaCrosse sedan. It goes on the rocker, and the note reads "Installs below the door." The width tapers from 1.625" to 3".
Three LaCrosse kits, three placements
QAA links three side kits for this sedan, and they aren't interchangeable:
- TH50520 (this kit): four pieces on the rocker, below the door, 1.625"-3" tapered
- TH50523: two pieces on the rocker, below the door, a straight 1.25"
- TH50521: an eight-piece Lower Kit that sits on the doors and lists a cut out for factory trim
The two rocker kits share the same placement note but differ in count and width. The record doesn't explain how their coverage differs, so compare the photos side by side. If they look alike to you, call 877-752-3811 before ordering.
A wide taper
From 1.625" at one end to 3" at the other, this piece nearly doubles in height along its length. The record doesn't say which end is which. Hold a piece in place with painter's tape and compare it with the photos to see how it follows the body line.
Wheel well trim note
WQ50520 is a four-piece wheel well accent noted "Cut to fit with Rocker kit sold separately," and WQ50521 is the "Full Length" version. The record doesn't say which rocker kit WQ50520 means. Ask us before pairing it with this one.

What it's made of
All four LaCrosse pieces are USA-made, polished 26 gauge 304 stainless steel, and bond onto the existing rocker surface with 3M automotive-grade acrylic foam tape. QAA says the tape will hold for a lifetime and won't harm the finish.
Rocker prep
The rocker sits low and collects road film. Wash it with a soft brush, rinse, dry, and wipe with isopropyl alcohol until the cloth stays white.
Placement
Tape each piece up, then open each door and check that its bottom edge clears the trim as it swings. Peel and press only once that's confirmed.
Following the taper
Measure from the LaCrosse's wheel openings to each piece end, then reuse those distances so the taper runs evenly.
First wash
Give the tape a day. After that, rinse salt off the rocker regularly in winter.
Questions
Choosing with a tape measure
Measure the height of the rocker area below your doors at the front and at the rear. Then compare those numbers with this kit's 1.625" and 3" and with the straight 1.25" of TH50523. That comparison, together with the photos, is the quickest way to narrow down the choice before you call.
Tools on hand
Painter's tape, isopropyl alcohol, a soft brush, towels and a measuring tape cover the job. A second person makes the longer pieces easier.
Day and place
Pick a mild, dry day and work in shade or a garage.

Installation tips: Rocker Panel Trim, On the rocker
- 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.
