Weatherstrip Seals & Felts, 1966-77 Ford Broncos

The early Bronco uses weatherstripping and seals at the door openings, hard top perimeter, tailgate, windshield frame, and various body seams. These rubber seals deteriorate with age and UV exposure, allowing water, dust, and noise into the cabin. Tom's Offroad carries complete weatherstripping kits for the 1966–1977 Bronco covering all major sealing surfaces.

Replacing early Bronco weatherstripping involves removing the old rubber by peeling or scraping it from the channel, cleaning the mounting surface with adhesive remover, and pressing or gluing the new seal into place. Door seals typically use push pins for alignment, but require gluing for proper sealing. Some seals, like the door felt kit, is built into a metal channel, so simply installing the channel is all that's needed. Hard top and tailgate seals often use a contact cement or pushpins. Work one section at a time to maintain alignment.

Water leaks in an early Bronco most commonly stem from deteriorated door weatherstripping, cracked or missing hard top seals, a worn tailgate seal, or a compromised windshield gasket. Diagnosing the source requires a careful inspection with water or a helper spraying the exterior while you watch from inside. Tom's Offroad carries replacement seals for every major leak point on the early Bronco. Proper body alignment, door gaps and a square tub allow the seals to fit properly. If the seal does not fill the void, there is likely some body alignment issues to address.

Replacing the early Bronco tailgate weatherstrip involves removing the old seal from the tailgate channel, cleaning any adhesive residue, and pressing the new seal into the channel using contact cement for security. Most owners apply a thin bead of black weatherstrip adhesive along the full length for a watertight seal. Allow the adhesive to fully cure before closing the tailgate.

Original and reproduction early Bronco weatherstripping is made from EPDM rubber, which resists UV degradation, ozone cracking, and temperature extremes better than older natural rubber formulations. Quality reproduction seals from Tom's Offroad use EPDM material that closely matches the original profile dimensions, ensuring proper compression fit and a long service life.
