2011 Chevy Impala OEM Factory Sunroof Glass.   The sunroof is in good used condition. Measurements are 33 3/8" long and 21 3/8" wide. This sunroof came on Impala model year 2011 but please double check your measurements and compare to ours.  Aftermarket sunroofs have become very popular over the last 10 years, this is why it is so important to double check your measurements. If you have a sunroof switch that looks like any in our last picture, you have an aftermarket, contact us we can help.Be wary of sellers stating this sunroof will fit other years and models, it will not, this glass was specific to the 2011 model.   This glass panel was removed from a 2011 Impala that had a blown engine so there is no unseen damage on this panel as is found with a majority of sunroof glass panels that are removed from wrecked vehicles. Often times on a wrecked vehicle, the metal trim around the glass, under the seal, will incur slight bends which will make the panel leak soon after. We have been dealing in sunroof glass panels for 20 years now and only sell the panels that come through our shop that are off of vehicles that have not been in major accidents. We also 100% inspect the panels, especially the seals, for any imperfections that may cause issues down the road. The sunroof comes read to bolt in.  Please contact us with any questions that you may have.
