[More Info]
The Precision Glass Weatherstrip Lockstrip WLS 848/853 SP is a replacement lockstrip designed to secure and align window glass inside the door channel, holding the weatherstrip in place and maintaining a tight seal. Engineered for corrosion resistance and long service life, this low-profile lockstrip reduces rattles, wind noise, and water intrusion while restoring proper window operation. Ideal for restoration and maintenance projects, it delivers reliable performance and straightforward installation when replacing worn or damaged factory lockstrips. Verify vehicle fitment prior to purchase to ensure compatibility.
Features:
  • Corrosion-resistant metal construction for long-lasting durability.
  • Secures glass in the door channel to prevent rattling and misalignment.
  • Helps hold weatherstrip in position to maintain a watertight seal.
  • Low-profile design preserves factory glass movement and clearance.
  • Suitable for restoration and repair of worn or damaged lockstrips.
Installation / Application:
  • Difficulty: 3/5
  • Estimated time: 30–90 minutes per door (varies by vehicle and experience)
Suggested Tools:
  • Flat trim removal tool
  • Phillips screwdriver
  • Socket set or nut driver
  • Needle-nose pliers
  • Utility knife or razor
  • Cleaning solvent and rags
  • Gloves
  • Protective tape (to mask glass edges)
Instructions:
  1. Park the vehicle on a level surface and disconnect the battery if the door has power components.
  2. Lower or raise the window as needed to access the lockstrip ends, then remove the interior door panel and any vapor barrier or water shield to expose the inner door cavity.
  3. Carefully lower the glass (if necessary) and remove any clips, screws, or retainers securing the old lockstrip and inner weatherstrip to expose the glass channel.
  4. Gently pry and pull out the old lockstrip from the glass channel, noting the orientation and how it seated against the glass.
  5. Clean the glass channel and surrounding area thoroughly with solvent and a rag; remove corrosion, old adhesive, and debris to ensure a good fit for the new strip.
  6. Test-fit the new WLS 848/853 SP lockstrip to confirm length and orientation. Trim carefully if trimming is required (follow vehicle-specific guidance).
  7. Seat the new lockstrip into the glass channel: align the lip correctly, press firmly along the length, and use steady pressure to engage it fully. Raise or lower the glass slightly if needed to help the strip seat evenly.
  8. Reinstall the inner weatherstrip, any retainers or clips, and test the window operation several times to confirm smooth movement and proper sealing.
  9. Reassemble the door panel and any removed components. Verify final fitment and check for wind noise or leaks on a test drive or with a water check.
