Frequently Asked Questions
Q: Do these doors come with a windshield and back panel?
A: No, the windshield and back panel are sold separately, but they are required to achieve a fully sealed cab enclosure[cite: 1].
Q: Can I roll down or store the windows while out on the trail?
A: Yes, the crystal-clear vinyl windows feature zippered openings and integrated storage provisions for easy open-cab riding[cite: 1].
Expert Pro-Tip: When installing soft canvas doors, let the material sit out in the warm sun for an hour prior to installation. This relaxes the UV-protected nylon canvas and vinyl, making it much easier to stretch over the steel frame for a tight, wrinkle-free fit.
