Product Description
Cadillac Limousine 64" Stretch, DeVille 2000-2005 / DTS 2006-2011: Under-Door Rocker Trim, 6 Pieces, 2.25" (TH40258)
For a 64" stretch Cadillac limousine, TH40258 puts six pieces of polished stainless steel under the doors. Each is 2.25" wide; the record files them "On the rocker" with the note "Installs below the door," and the width line includes "64" extension." The fitment row and the title cover the DeVille 2000-2005 and the DTS 2006-2011.
Where the 64" figure appears
It appears in the fitment row ("64" Stretch") and the width line ("64" extension"). The trim tag itself simply reads "Limousine." Nothing names a coachbuilder. Confirm the stretch from your paperwork before ordering; if you can't, send photos to 877-752-3811.
Nothing linked
This sheet has no siblings, so no door-mounted kit is paired with it here. If you'd like steel on the doors as well, ask us what exists for your stretch.
Steel and adhesive
Cut in the USA from polished 26 gauge 304 stainless, the six pieces for the 64" stretch DeVille and DTS limousine attach below the doors with 3M automotive-grade acrylic foam tape over the existing surface. QAA says the tape will hold for a lifetime without harm.
How the pieces divide
The record gives a count of six and nothing about lengths or positions. Treat the product photos as the plan, sort the pieces, and label the liners.
Look before you start
Close every door and look along the rocker. A clean, flat band about two and a quarter inches tall is what the steel needs. Repair any chips and let the paint cure before installing.
Preparing the rocker
Soap and water, a thorough rinse, and complete drying come first. Isopropyl alcohol on a clean cloth removes what's left. Change cloths as they pick up grime.
Marking
Measure down a fixed distance from the door bottoms and place painter's tape marks every couple of feet. On a long car that's the easiest way to keep the line straight.
Installing
- Dry-fit the 64-inch stretch pieces with painter's tape first.
- Peel a few inches of liner, set the piece on the marks, and press.
- Keep peeling and pressing to the end, then go back with firm pressure.
Wrapping up
Check that every door opens and closes freely without touching the steel. Check the line from a few steps back. Give it a day before washing.
When to call
Unsure of the stretch, the base car, or whether the panels match the photos? Year, nameplate, stretch figure and a side photo are all we need.
Weather and pacing
Install on a dry, mild day or in a garage, and let cold parts warm up before peeling liner. Finish one full side, step back to check it, then move to the other.
Care
Wash the trim with the rest of the car using a soft mitt and mild soap, and dry it so water doesn't spot the polish. Avoid scraping ice or packed snow off the steel with anything hard.

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.
