Product Description
Cadillac DeVille 2000-2005 & DTS 2006-2011 Sedan Lower Rocker Kit, 6.5", 8 Pieces (TH40243)
TH40243 is the taller of two sedan Lower Kits QAA links for the Cadillac DeVille (2000-2005) and DTS (2006-2011). Both appear in the title, each with its own span. It's eight pieces of polished stainless steel, 6.5" tall, set "from the bottom of the door UP to the specified width."
6.5" or 4.5"
TH40245 is the other sedan Lower Kit: same eight pieces, same tag, same placement, but 4.5". The record doesn't say why two heights exist for the same car. It's a choice of look, and only you can make it. Run painter's tape at six and a half inches on one door and four and a half on another, then step back. If neither looks right or your doors differ from the photos, call 877-752-3811.
Below the door
TH40248 is a four-piece "On the rocker" kit, 2.25", that "Installs below the door." Whether it's meant to pair with either Lower Kit isn't stated; ask before ordering both.
Accessories
Pillar post trim: PP40245 (four pieces) and PP40246 (six pieces), plus PP40246-OL ("OUTLINE TRIM only, 1/2" Surround"). PP40243 is also linked but tagged "Federal Hearse," not sedan. Wheel well fender trim moldings WZ40245 and WZ40245-AP are four pieces at 1.25" with matching tags. Check each listing.
Material
The DeVille and DTS sedan takes eight 6.5" strips cut in the USA from polished 26 gauge 304 stainless steel, set on 3M automotive-grade acrylic foam tape from the door bottom up over the existing surface. QAA states the tape will hold for a lifetime without causing any harm to the Cadillac.
Eight pieces
The record doesn't map them. Match each piece with the photos and label the liners.
Door bottoms
The steel starts right at the lower edge. Repair chips or bubbles there first.
A taller band to place
Six and a half inches is a fair amount of steel. Hold each piece with painter's tape, check the bottom edge against the door and the top edge for level, then peel a few inches and set it. Work across with steady pressure, pushing air toward the open end.
Prep
Clean, dry and alcohol-wipe the DTS lower doors.
Doors
Open each fully after its piece goes on.
Supplies
Tape measure, painter's tape, marker, car soap, isopropyl alcohol, towels and a plastic squeegee.
Care
Keep the DTS unwashed for a day.
Matching
Keep positions consistent from piece to piece.
What to send when you call
The nameplate and year, a side photo, and which height you're leaning toward. If you're also considering the rocker kit or pillar trim, mention it and we'll confirm everything together.
Line check
Sight along the car from the front bumper after each piece so the top edges read as one line across the door gaps.
Choosing between heights
The taller band covers more of each lower door; the shorter one leaves more paint showing above it. Neither record calls one better. Your preview with painter's tape is the honest test, and we're happy to talk it through.

Installation tips: Rocker Panel Trim, Lower Kit
- Unpack all 8 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.
