Product Description
Cadillac DeVille / DTS Limousine, 46" Stretch: Rocker Panel Trim Below the Doors, 6 Pieces (TH40256)
The number to check on TH40256 is 46. The record is tagged "Limousine, 46" Stretch," the width line reads "2.25" Width, 46" extension," and the fitment row and the title cover the Cadillac DeVille 2000-2005 and the DTS 2006-2011. It's six polished stainless steel pieces filed "On the rocker" that install below the door.
Measure the stretch before anything else
There are several limousine records in this Cadillac group and they look much alike. The stretch figure is what separates them, so pull your conversion paperwork and confirm 46" before you order. If you can't find it, call 877-752-3811 with photos of the full side.
The linked door kit
TH40239 is the one sibling on this sheet: ten pieces, 4.5" wide, a Lower Kit tagged for the 46" stretch, with "46" Between the wheel wells" in its note. It starts at the bottom of the door and rises, while TH40256 sits underneath the doors. The record doesn't say whether they're meant as a pair; ask us if you're considering both.
What you're getting
- Six USA-made limo pieces in high-quality polished 304 stainless, 26 gauge.
- Each 2.25" wide.
- They go on the limo as it is, using 3M automotive-grade acrylic foam tape.
On the 46" stretch DTS limousine, QAA says the tape will hold the six strips for a lifetime without harming the paint.
Placement unknowns
The data doesn't describe where each of the six pieces begins or ends along the stretched body. Use the product photos as your map and lay the pieces next to the car in order before peeling any liner.
Low-down prep
Rockers catch spray from the tires, so they need more than a quick wipe. Wash with soap, scrub the lower edge, rinse, and dry fully. Then go over the band with isopropyl alcohol. Touch up chips and allow them to cure.
Laying the line
Painter's tape marks at even intervals, all the same distance below the door bottoms, give you a straight reference along a long body. Sight down the marks from the bumper before you start.
Installing
Peel a short length of liner from one end, set it on your marks, press, and keep peeling and pressing to the far end. Go over each finished piece with firm pressure.
Afterward
Open and close each door. Look over the car from front and rear. No washing for a day.
Handy to have
Kneeling pad, work light, long tape measure, microfiber cloths, painter's tape.
Before ordering
Three things to confirm: the base car is a DeVille or DTS in the listed years, the stretch is 46", and you want trim beneath the doors rather than on them. If all three check out, this is the record. If one doesn't, call before you buy so we can point you to the right one.
Conditions
Work out of direct sun on a dry, mild day, or indoors. A long body means a long job, so give yourself time and don't rush the later pieces.

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