Product Description
GMC Sierra 1500 Xtra Cab 4-Door Short Bed, 1999-2006, w/o Factory Flares: 12-Piece Upper Rocker Kit, 5.5" (TH39287)
The record tags TH39287 as "4-door, Pickup Truck, Xtra Cab, Short Bed, w/o Factory Flares, Sierra 1500," model years 1999-2006. It's the twelve-piece short bed kit for the four-door Xtra Cab: polished stainless steel, an Upper Kit 5.5" wide, set below the molding.
Twelve, eleven or ten
Piece count tracks the cab in this group. Four-door Xtra Cab: twelve (this kit, and TH39289 for the long bed). Three-door Xtra Cab: eleven (TH39285, TH39286). Regular Cab: ten (TH39281, TH39282). The record doesn't describe where the further pieces go; call to ask.
A four-door Xtra Cab
The group lists the Xtra Cab with both three and four doors. Count rather than assume. Four doors and a short bed point here.
Molding to steel
Each piece's top edge tucks under the molding, and the steel reaches five and a half inches down. On your truck, confirm there's at least that much painted surface below the molding. A quick strip of painter's tape at that depth shows you the finished band.
Factory flares
Every kit in the group is tagged without them. If your truck has factory flares, call 877-752-3811 before ordering any of these.
Made from
Sierra trim: polished 304 stainless, 26 gauge, USA-made.
Mounted with
The Xtra Cab pieces bond with 3M automotive-grade acrylic foam tape. Per QAA, the tape will hold for a lifetime without damaging the Sierra.
Planning twelve pieces
Lay all twelve on a clean towel beside the truck in the order the photos suggest. Sort them by shape. Mark each liner with its position. Only then start peeling.
Molding condition
The molding is the straight edge for the whole job. Loose or lifting sections need re-securing beforehand.
Prep sequence
- Wash the band below the molding.
- Rinse the Sierra; dry it fully.
- Isopropyl alcohol wipe.
- Fix flaking paint first.
Applying
Test-fit with painter's tape. Start a few inches of liner at one end, set it, and press steadily toward the other end as the liner comes off. Firm pressure across the face to finish.
All four doors
Open each door fully after its piece is down and look at the gaps.
Bare wheel openings
No flares means end pieces near the openings sit on plain body; dry-fit them carefully.
Afterward
Wash after a day, with mild soap.
What we'd ask if you called
How many doors, which bed, whether there are flares at the wheel openings, and whether the molding is the original. With those four answers and a photo of the whole side, we can confirm the kit or point you to its neighbor in the group in a couple of minutes.
Gear
Painter's tape, a marker, a tape measure, car soap, isopropyl alcohol and a stack of clean microfiber towels. Work in shade on a mild, dry day.
One line along the truck
Once the first pieces are on, measure where each starts and ends relative to the door edges and keep later numbers consistent, so the band reads as one line.

Installation tips: Rocker Panel Trim, Upper Kit
- Unpack all 12 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.
