Product Description
GMC Sierra 1500 Xtra Cab 3-Door Short Bed, w/o Factory Flares (1999-2006): Upper Rocker Kit 5.5", 11 Pieces (TH39285)
TH39285 is tagged for the 1999-2006 GMC Sierra 1500 Xtra Cab with three doors and the short bed, without factory flares: "3-door, Pickup Truck, Xtra Cab, Short Bed, w/o Factory Flares, Sierra 1500." Eleven pieces of polished stainless steel, an Upper Kit 5.5" wide, set below the molding.
Count your doors
The Xtra Cab appears twice in this group with different door counts. Three-door versions have eleven pieces (this kit and TH39286 for the long bed). Four-door versions have twelve (TH39287 short bed, TH39289 long bed). The record doesn't explain the door arrangement beyond the count, so count yours and match it. If you're unsure, a side photo and a call to 877-752-3811 will settle it.
Regular cab kits
TH39281 and TH39282, ten pieces each, cover the regular cab short and long bed.
Flares
The tag says "w/o Factory Flares." A truck with factory flares isn't listed here.
Under the molding
The steel's top edge meets the molding and its lower edge sits five and a half inches below. Hold painter's tape at that depth on one door to preview.
Stainless steel
The eleven Sierra pieces are polished 26 gauge 304 stainless steel made in the USA, fixed over the existing surface with 3M automotive-grade acrylic foam tape. QAA says that tape will hold for a lifetime without damaging the truck's surface.
Eleven pieces
The odd count doesn't divide evenly between sides, and the record doesn't map it. Lay out the set with the product photos and settle every piece's spot before peeling.
Molding
Re-secure any loose molding before starting; it defines the top line.
Clean and inspect
Wash below the molding, dry thoroughly and wipe with isopropyl alcohol. Fix flaking paint in the band first.
Install
- Painter's-tape every Sierra piece up first.
- Free the liner's first few inches, then fix that end.
- Keep pressing as the backing pulls away.
- Then press hard over the full strip.
Third door
After each door piece, swing the door and inspect the edges.
Wheel openings
No flares here, so dry-fit end pieces near the openings carefully.
Care
Keep the Sierra dry overnight.
Sides
Keep every Sierra piece consistent with the photos.
Before ordering
Five checks: 1999-2006 Sierra 1500, Xtra Cab with three doors, the short bed, molding present, and no factory flares. All five match this record. If the door count or flares are uncertain, send a side photo and close-ups of the wheel openings with your call to 877-752-3811.
Tools
For the Xtra Cab: tape measure, painter's tape, a liner marker, car soap, isopropyl alcohol and lint-free towels, on a mild, dry, shaded day.
Molding preview
To preview the look, run painter's tape five and a half inches under the molding on the Sierra's front door; the paint below that line stays visible.
A final look
Before you peel the first liner, step back and view the whole side with every piece taped in place. Adjust anything that looks off.

Installation tips: Rocker Panel Trim, Upper Kit
- Unpack all 11 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.
