Windshield header and soft tops
A windshield header ties the soft top to the front of the vehicle, so it carries wind load and keeps the top in shape at the windshield. Bikini and Brief style tops rely on the header to stay tight, which makes the attachment points worth checking before every trip.
A quick detach design is useful when the top comes off for summer use, but the header should still be stored clean and dry. Check the channel for debris before reattaching it, and inspect the fasteners for wear or corrosion. A header that sits loose can rattle, let in water or allow the top to flap. Keep the top’s fabric clear of the header’s edges so it does not wear.
- Clean the windshield channel before reattaching
- Inspect fasteners for wear
- Store the header clean and dry
- Check top seals after installation
