Detailed Description

Dorman 25863 is a door window seal designed to replace worn original weather stripping around the door glass. The felt construction helps maintain contact with the window edge, supporting a tighter barrier against outside elements. This part is a specific-fit replacement, not a universal trim piece, and it is shaped for the rear right outer window application on the listed Chevrolet, GMC, and Cadillac vehicles.

Use part number 25863 when the original seal has hardened, split, or pulled away from the window channel. It is a practical replacement for owners searching for a rear right outer door window seal for a 2000-2006 Chevrolet Suburban 1500 or 2500, a 2001-2006 GMC Sierra 2500 HD, or a 2003-2006 Cadillac Escalade ESV.

What It Helps Fix

• Wind noise around the rear door glass
• Water intrusion past damaged window weather stripping
• Dust and road debris entering through worn seals
• Rattling or loose-feeling window sealing surfaces
• Visible cracking, tearing, or shrinkage in the original strip

Installation Notes

Install on the rear right outer door window location only. The snap-on, non-adhesive design is intended to replace the original strip without cutting to fit. Confirm vehicle year, make, model, and position before installation, especially on 2007 Classic body-style trucks and earlier GMT800 applications. Part number 25863 should be matched to the exact rear right outer fitment listed for your vehicle.

Quality Assurance

Dorman manufactures replacement body sealing components for direct-fit service applications. This door window seal is built to match the specified fitment and dimensions for the listed vehicles, helping restore the original sealing function at the window opening.
