Built to raise and lower the front right door glass by hand crank, the Dorman window regulator 740-518 is a manual replacement regulator supplied as the regulator only. It fits many vehicles, among them the 1999-2006 Chevrolet Silverado 1500, 1999-2007 Chevrolet Silverado 2500 and 1999-2006 GMC Sierra 1500. See the "Vehicles it fits" section for the full list.
This Dorman OE Solutions window regulator is precision-engineered and put through extensive testing so it matches the stock regulator's fit, function and performance on the listed applications.
- Trustworthy replacement: Engineered and tested against the original window regulator's fit, function and performance for the vehicles it is cataloged for.
- Quality assured: Cycled thousands of times inside an actual vehicle door during testing.
- Reliable design: Engineered in the USA and backed by Dorman's long history in the automotive aftermarket.
- Easy installation: Reverse-engineered to the original equipment shape and dimensions for a direct, seamless fit.
Signs a window regulator may need replacing include glass that moves slowly, sits crooked or drops into the door, grinding or clicking as you crank, or a handle that turns without moving the window. Diagnose the cause first. If a failed front right regulator is behind the problem, 740-518 replaces it.
