Trektop NX is the next generation in modern soft tops for Jeep Wrangler. Fastback styling with a fresh, taut fit that doesn’t need traditional bows or frames to install. Premium factory-spec sailcloth fabric has best-in-class UV resistance for years of fade-free durability. Removeable, replaceable tinted windows are standard, as is the Sunrider-style fold back sunroof. Factory-style polymer door surrounds and tailgate bar included to complete the kit. Top Arch Bar (JK 4-door models get two) helps prevent water puddling and reduces any flapping. Choose the optional door style you want; use existing full steel doors, or any Bestop door kit (sold separately) including 2-Piece Doors, Upper Fabric Doors, Element Doors or Lower Fabric Half doors.
