Frequently Asked Questions
Do I need to buy bolts and fasteners separately?
This assembly mounts at factory attachment points—fasteners are not included. Use your existing OEM hardware or pick up replacement bolts at any hardware store if yours are stripped.
Will this assembly work if my regulator tracks are bent or damaged?
The assembly installs into existing door tracks. If your tracks are bent or dirty, clean them out and straighten minor bends before installation—the new regulator won't compensate for damaged guideways.
Can I return this if it doesn't fit after I receive it?
Test-fit before fully committing to installation. If there's an issue, contact support with photos—returns are handled case-by-case within the standard return window.
