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.

Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.

No, parts from Mopar, ACDelco, and Motorcraft are typically designed for specific vehicle brands. It’s crucial to ensure compatibility with your vehicle’s make and model by checking part numbers and consulting with a knowledgeable expert.
Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.

Yes, many OEM auto parts come with a manufacturer’s warranty that covers defects or issues. Be sure to check the warranty details for each part at the time of purchase, and keep your receipt for any potential warranty claims.
