Glass Weatherstrip Lockstrip | Chevy GMC 1973-1991

$82.27

Glass weatherstrip lockstrip for 1973–91 Chevy and GMC Suburban and crew cab pickups, a black ozone-resistant insert that locks the glass into the weatherstrip.

  • Locks the glass down - driving the strip into the groove spreads the weatherstrip hard against the pinchweld.
  • Ozone resistant - the failure mode of the original strip was brittle rubber; this material resists it.
  • Black to disappear - reads as trim rather than as a repair on a Suburban or Crew Cab body.
  • Correct profile - cut for the Chevrolet and GMC groove rather than trimmed from universal stock.
  • Finishes the job right - the one part a glass install stalls without.

Install Level: Advanced

Lockstrip only. Weatherstrip and glass are separate.
For 4-door Suburban and crew cab bodies only.
Install during glass replacement. Professional installation is recommended.

SKU: WLS 5351/52 B
