Customer Reviews

Rear, Driver Side, Lower Direct Fit Quarter Panel Extension
Will make it work
Panel came quickly and was reasonably priced. 4/5 as I had to order an off model year and improvise welding this in for a close enough match for a 2010 Avalanche. Didn't want or need to replace the whole quarter.

Beyond what I expected!
The service was great! Got my parts pretty quick so that helped me get started on my project sooner. I’m almost halfway done now and the truck is looking great! Thanks the parts exceeded my expectations!
