Product Description
TH55150: 8-Piece Lower Door Trim for the 2015-2022 Chevrolet Colorado Crew Cab Long Bed
TH55150 is an eight-piece polished stainless steel Lower Kit for the 2015-2022 Chevrolet Colorado, listed for the 4-door Crew Cab pickup with the long bed (6.2'). The record gives a tapered width of 3.125" to 4.625" and one detail that shapes the whole job: the pieces come "with cut out for factory trim."
What "cut out for factory trim" tells you
The record says each kit is shaped to leave room for trim already on the truck, but it doesn't describe that trim or show where the openings fall. Before you order, look at the product photos and compare the shape of the cut-outs with the lower doors of your Colorado.
Placement on the door
This is a door kit, not a rocker strip. The listing says it "Spans from the bottom of the door UP to the specified width," so the steel starts at each door's lower edge and climbs to somewhere between 3.125" and 4.625", depending on where along the taper you measure. Which end of each piece is the taller one isn't spelled out, so the photos are the reference for orientation.
The bed length matters
The fitment line names the long bed (6.2') specifically. The record doesn't list a short-bed Colorado for this kit, so if your truck has a different bed, call us before you buy rather than assuming it carries over.
Material and adhesive
Colorado Crew Cab long bed owners get eight tapered pieces, cut out for the factory trim, of USA-made polished 26 gauge 304 stainless, all carried on 3M automotive-grade acrylic foam tape. QAA states the tape will hold for a lifetime with no harm to the truck.
Laying out eight pieces
The record doesn't map the eight pieces to doors. Unpack them on a towel, sort them by shape, and use the photos to decide where each one sits.
Clean lower doors first
Wash the bottom of each door, rinse well, and let it dry. Then wipe the area with isopropyl alcohol so the tape meets bare, clean paint rather than wax or grime.
A trial fit around the cut-outs
Hold every piece in place with painter's tape before peeling anything. Check that each cut-out lines up with the trim it is meant to clear and that the bottom edge follows the door. Open and close the doors to confirm nothing rubs.
Setting the steel
Start at one end, peel a short length of liner, set the piece on your marks and press. Keep peeling and pressing in small steps, then go back over the full length with firm hand pressure.

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.
