Product Description
2005-2009 Buick LaCrosse Wide Lower Door Trim, 6", 8 Pieces (TH45521)
TH45521 is the wide Lower Kit for the 2005-2009 Buick LaCrosse four-door sedan: eight polished stainless steel pieces at 6", spanning "from the bottom of the door UP to the specified width."
Six inches is a lot of door
This kit covers the bottom six inches of each door. Before ordering, put a strip of painter's tape at that height across a front door and a rear door and look at where it lands. If it runs into molding, a handle area, or a body line, the narrower kit is the one to consider. Measure carefully.
The narrower twin
TH45520 is the same kind of kit for the same car and years, also eight pieces, at 3.5". The record doesn't say what decides between them other than width. If both are possible on your LaCrosse, call 877-752-3811 and describe your measurement.
Bottom edge as reference
The lower edge of each door sets the line for the whole kit, so it needs to be straight and in good shape. Check underneath with the door open; repair chips or rust first.
Eight pieces
The data gives no layout for the eight. Match each to the product photos and number the liners by door and side.
Steel and tape
The eight 2005-2009 LaCrosse pieces are polished 26 gauge 304 stainless steel from the USA. They go on over the existing door surface with 3M automotive-grade acrylic foam tape, which QAA states will hold for a lifetime without damage to the Buick.
Clean a tall band
A 6" kit means more surface to prep. Wash, rinse and dry the lower doors, then wipe the full band with isopropyl alcohol, working the cloth in overlapping passes.
Mounting
Hold each piece with painter's tape and close the door to check the gaps. Open it, peel a short length of liner, set the end flush with the bottom edge, and press upward and along as the liner comes away. Firm pressure over every inch at the end.
Matching doors
The top edges should meet at the same height across each door gap. Check from a few feet back.
Linked accessories
DS45520 door sills, PP45520 / PP45521 / PP45522 pillar post kits, RD45520 rear deck accent, RI45520 roof insert, and WZ45520 wheel well fender trim.
Clearance
Open and shut every door after installing to make sure nothing rubs.
Care
A day before the first wash; mild soap and a soft mitt afterward.
Conditions
Garage or dry, mild weather.
A helper
Wide pieces are easier to align with someone holding the far end.
Before ordering
Measure up from the bottom edge of the front and rear doors. If you have six inches of clear, flat door before you reach molding or a body line, this kit fits that space. If you have less, look at TH45520 or send the measurements and a photo to 877-752-3811.
Bottom edge tip
Sight along each door from the end with it open; smooth any lip or ding first.

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.
