Product Description
Buick Century CST/LTD 1997-2004 Lower Rocker Trim, 8 Pieces, 5.25" (TH37540)
TH37540 fits the 1997-2004 Buick Century sedan, and its fitment row sets a trim limit: "4-door, Sedan, CST/LTD." That tag is the first thing to check. The kit is eight pieces of polished stainless steel, a Rocker Panel Trim Lower Kit 5.25" wide.
The trim tag
The record names CST and LTD and nothing else. It doesn't say whether other Century trims share the same door shape, so we can't tell you this fits them. If your car carries a different badge, or none you can find, call 877-752-3811 with a side photo and we'll check.
Where the band goes
"Spans from the bottom of the door UP to the specified width." The steel starts at the lower edge of each door and climbs five and a quarter inches. A strip of painter's tape at that height on one door gives you a preview of the finished look before you buy.
Eight pieces on four doors
The data gives the count but not a layout. Use the product photos to sort the pieces and match each to its door. Labeling each liner with a bit of painter's tape saves confusion halfway through.
Nothing else linked
No sibling SKUs are attached to this record, so there's no alternate width or companion kit to compare here.
Steel and tape
Every Century piece is polished 26 gauge 304 stainless steel from the USA, mounted over the existing surface with 3M automotive-grade acrylic foam tape. QAA states the tape will hold for a lifetime without causing damage to the sedan.
Inspect the lower edge
A Lower Kit lives at the very bottom of the door, where stone chips and moisture collect. Check each door's lower edge for chips or rust bubbles and repair them before the trim goes on.
Fitting it
- Wash, dry and alcohol-wipe the lower doors.
- Dry-fit each piece, lower edge level with the door bottom.
- Mark both ends with painter's tape.
- Peel a little liner, set the front end, then press along as the liner comes free.
- Press the finished piece firmly from end to end.
Even Century spacing
Measure each piece from the door edges and keep the same figures for the rest.
Clearance check
Open each door all the way after its piece is down and watch the gap at the bottom and trailing edge.
Weather
Choose a dry, mild day and keep the car out of direct sun while you work.
Living with it
Wait a day before washing. Mild soap and a soft towel keep the polish bright.
Before you order
Confirm three things: the year falls between 1997 and 2004, the car is a four-door Century sedan, and it carries the CST or LTD trim the record names. If all three check out, this kit is the match the data gives. Any doubt, send a photo of the badge and the side of the car with your call.

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.
