Product Description
Six-Door Cadillac DeVille Limousine, 60" Stretch (2000-2005): Full Length Lower Kit, 14 Pieces, 4.5" (TH40257)
TH40257 is the biggest kit in this DeVille group by piece count: fourteen pieces of polished stainless steel, 4.5" wide, for a six-door limousine with a 60" stretch on the 2000-2005 Cadillac DeVille. The width line reads "Full Length, Includes coverage from the wheel well to the bumper on the front and rear, 60" extension," and the kit "Spans from the bottom of the door UP to the specified width."
Six doors, fourteen pieces
The tag says six-door. The record doesn't break down which pieces go on which doors or panels, so the product photos are the reference. Before buying, count the doors on your car and confirm the 60" stretch from your conversion paperwork. Different door counts or stretch figures mean a different record.
DeVille only
Unlike several limousine kits nearby that list both DeVille and DTS, this row lists only the DeVille 2000-2005. If your limousine is DTS-based, call 877-752-3811 rather than ordering this one.

Material
QAA makes the fourteen pieces for the 60" stretch DeVille limousine in the USA from polished 26 gauge 304 stainless steel; they go over the existing surface with 3M automotive-grade acrylic foam tape. Per QAA, the tape will hold for a lifetime without causing damage.
Plan the whole side
Fourteen pieces on a long body is a job for some floor space. Lay the pieces out in order next to the car, compare with the photos, and number the liners. Keep them in that order until each one goes on.
Clean the full length
The coverage note reaches from wheel well to bumper at both ends, so prep the lower body from front to back. Wash, dry, alcohol-wipe, and repair any chips first.
Fitting
Hold every piece in place with painter's tape before peeling anything. When the line looks continuous across all the door gaps, start at one end: peel a few inches, set the bottom edge, press along, finish with firm pressure.
Final checks
Open all six DeVille doors, sight down the rockers, and wait a day to wash.
A two-person job
Long pieces on a long car are easier with a helper: one person holds the far end off the paint while the other sets the bottom edge and presses along. It keeps the liner clean and the line straight.
Fourteen pieces in line
As each piece goes on, measure from the nearest door gap to its end and keep those distances in step, so the car looks even from either curb.
What to send if you're unsure
A photo of each full side, the door count, the stretch figure from the paperwork, and the model year. With those, we can confirm this kit quickly by phone or email.

Installation tips: Rocker Panel Trim, Lower Kit
- Unpack all 14 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.
