Product Description
Chevrolet Impala 2014-2020 Lower Kit, 3"-4.375" Tapered, 8 Pieces - Not for the Limited (TH54135)
TH54135 is an eight-piece polished stainless steel Lower Kit for the 2014-2020 Chevrolet Impala sedan. It spans from the bottom of each door up and tapers from 3" to 4.375". The fitment row ends with "Does not fit the Limited."
The Limited exclusion
That exclusion appears on this kit and on every linked Impala part. The record doesn't say why. Check your badges or paperwork. If your Impala is a Limited, or you're unsure, call 877-752-3811 before ordering.
A tall band
At up to 4.375", this is substantial door coverage, and the inch-and-three-eighths taper changes its height clearly along the door. The record doesn't say which end is taller. Tape a piece up and compare it with the photos.
Linked Impala parts
Fourteen other listings are linked. Among them are pillar sets PP54135 and PP54136, a 2.5" rear bumper accent (RB54135), a 0.875" deck accent (RD54135), headlight accents (HL54135), a gas door cover (GC54135) and a license plate bezel (LP54135). Two wheel well kits carry notes: WQ54135 is "Cut to fit with Rocker kit sold separately," and WQ54136 is "Full Length, rear trim pieces are segmented into two." The mirror covers (MC54135, "Snap on replacement set," and MC54136) and DH54135 are listed as Chrome Plated ABS plastic. DH54135B and DH54137B are gloss black plated, and DH54137B is tagged "w/4 smart key." Check each listing for its finish, and ask us before pairing WQ54135 with this kit.
Material
The 2014-2020 Impala kit tapers across eight pieces of polished 26 gauge 304 stainless from a USA shop, and 3M automotive-grade acrylic foam tape holds them on the doors. QAA states that tape will hold for a lifetime with no harm to the sedan.
Previewing
Mark three inches up at one end of a door and about four and three-eighths at the other with painter's tape, join them, and look from the front corner.
Eight pieces
No layout is given. Match the pieces to the photos and label each liner.
Prep and install
Wash, dry and alcohol-wipe the lower doors. Tape each piece up, swing the door, then peel and press.
Door swing
With each piece taped up, open the door slowly and watch its bottom edge and the hinge side. Nothing should rub the steel at any point in the swing.
Contact
What to send when you call
The year, the trim badge, a side photo taken square on, and a close-up of the lower doors. Those answer the Limited question and the fit question together.
Bottom edges
Check the lower edge of each door for chips or flaking paint and repair them first, since the tape needs sound paint.
Help, weather and care
A helper keeps the taller pieces level. Work on a mild, dry day in shade, and wait a day before washing.
Mirroring the taper
A taper this tall makes small mismatches obvious, so measure both ends of each piece and keep the figures exact.
Impala owners can ring 877-752-3811 about the eight pieces under TH54135, UPC 691821737734.

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.
