Frequently Asked Questions
Do I need new fasteners to install these, or will OEM bolts work?
Factory bolts will work fine. These mount at the original attachment points — no special hardware required. Grab your socket set and you're good.
Can I install one side at a time, or do both doors need to come apart together?
One at a time, no problem. Each assembly is independent. Do the driver side, test it, then move to the passenger side whenever you're ready.
What if the window doesn't move smoothly after installation?
Check that the regulator tracks are clean and aligned inside the door panel — debris can bind the mechanism. If tracks are clear and it still binds, the assembly may have shipped with a defect. Contact us with photos and we'll make it right.
