Product Description
2005-2011 Cadillac STS Lower Door Trim, 1.125", 6 Pieces (TH45237)
TH45237 runs a narrow 1.125" line of polished stainless steel along the bottom of the doors on a 2005-2011 Cadillac STS four-door sedan. The record has two notes: "On the bottom of the doors" and "Spans from the bottom of the door UP to the specified width." Six pieces make up the kit.
A thin band on the doors
At just over an inch, this is a slim accent along the lower door edge. The steel's bottom follows the door's bottom edge, so that edge is the reference for the whole install. If you want a wider look lower down, the linked TH45236 is a four-piece, 2" kit that installs below the door on the rocker. Whether the two are meant to be combined isn't stated; ask at 877-752-3811.
Six pieces, four doors
The data doesn't explain why there are six pieces for four doors or which door gets more than one. Call to confirm. Match each piece to the product photos, lay them out by door, and number the liners.
Door edge check
Open each door and run a finger along the bottom. It should be straight, clean and free of chips. Since the trim sits flush with that edge, any flaw there shows. Fix it first.
Material and adhesive
The six 1.125" STS strips sit on the bottom of the doors; they are USA-made polished 26 gauge 304 stainless steel set with 3M automotive-grade acrylic foam tape over the existing surface. According to QAA, the tape will hold for a lifetime with no damage to the 2005-2011 Cadillac.
Surface prep
Wash, rinse and dry the lower door skins, then wipe a band a little wider than 1.125" with isopropyl alcohol. Get right down to the edge.
Setting each piece
Painter's tape holds a piece while you check it with the door closed. Look at the gaps front and rear. Then open the door, peel a short bit of liner, set the end flush with the bottom edge, and press along while the liner comes out. Press the whole piece firmly once it's down.
Across the door gaps
The front and rear door pieces should line up at the same height across each gap. Check from a few feet back before committing the second door.
Linked STS accessories
PP45236 and PP45237 pillar posts, GC45236 gas door cover, LP45236 license plate bezel, RD45236 rear deck accent, and WZ45236 wheel well molding are on this record.
Afterward
Open and close every door a few times and watch for rubbing. Leave the tape a day before washing.
Care
Mild soap, water and a soft cloth. No abrasive pads or polishing compound.
Conditions
STS install: garage or a dry, mild day.
Before you order
Confirm it's an STS sedan from the listed years, that you want the trim on the doors rather than the rocker, and that the lower door edges are in good shape. Photos to 877-752-3811 help if you're unsure.
Tip on the bottom edge
Sight along each door from the end with the door open. If the lower edge has a lip or a ding, smooth that first so the steel sits flush.

Installation tips: Rocker Panel Trim, Lower Kit
- 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.
