Product Description
41" Stretch Cadillac Limousine: Six-Piece Rocker Trim Under the Doors, 2.25" (TH40255)
TH40255 is for a Cadillac limousine with a 41" stretch, listed for the DeVille (2000-2005) or the DTS (2006-2011). It's six pieces of polished stainless steel, 2.25" wide, filed "On the rocker," with the note "Installs below the door." The width line also carries "41" extension." The title and the fitment row name both Cadillacs.
Pairs on the sheet with a door kit
This record links to one sibling, TH40238: a ten-piece Lower Kit, 4.5" wide, tagged for the same 41" limousine, with the note "41" Between the wheel wells" and a placement that starts at the bottom of the door and rises. So the two records describe different zones of the same car: TH40238 on the doors, TH40255 beneath them. The data doesn't say the two are designed to be installed together, so if you want both, call 877-752-3811 and we'll go through how they sit relative to each other.
Which stretch do you have?
The figure that matters is 41". Other DeVille and DTS limousine records in the catalog carry different stretch figures, and some name a coachbuilder. This one doesn't name a builder. Check your conversion paperwork for the stretch length before ordering. If the paperwork is missing, a photo of the full side and a measurement help us confirm by phone.
Build and attachment
For the 41" extension DeVille and DTS limousine, six 2.25" strips cut in the USA from polished 26 gauge 304 stainless steel go below the doors with 3M automotive-grade acrylic foam tape over the existing surface. Per QAA, that tape will hold for a lifetime with no damage.
The rocker band
Kneel by the car with the doors shut and study the panel under them. You need a flat stretch about two and a quarter inches tall for the steel. Any chips or bubbles there should be repaired and cured first.
Sorting six pieces
No layout comes with the record. Match the pieces to the product photos and label each liner. Dry-fit a run with painter's tape so you can see the whole line before committing.
Applying, step by step
- Wash, rinse, and dry the rockers; wipe with isopropyl alcohol.
- Mark a line a consistent distance below the door bottoms with painter's tape.
- Peel a few inches of liner, set the piece on the line, and press as you peel the rest.
- Finish each limousine piece with firm pressure along its length.
Clearance and spacing
Open every door to be sure its bottom edge clears. Then measure from a door gap to the end of the nearest piece and check it against the photos.
Living with it
Let it sit a day before the first wash. After that, regular washing with mild soap keeps the polish clear of road film.
Weather
Dry, mild conditions or a garage. Cold tape and cold paint don't bond as quickly, so let both warm up before you start.

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.
