Overview

The Bestop Trektop NX Slantback Soft Top (Black Twill) is the best-selling premium soft top engineered exclusively for the 2018–2026 Jeep Wrangler JL 2-Door — and the first fastback-style aftermarket top ever made for the JL platform. Built for Jeep enthusiasts who demand year-round versatility, this all-season soft top delivers a sleek, wrinkle-free fastback silhouette combined with the open-air freedom of a Sunrider flip-back sunroof and full bikini top capability. Whether you're daily-driving or hitting the trails, the Bestop Trektop NX Black Twill is the definitive premium soft top upgrade for your JL.

Key Features & Benefits

• First Fastback Top for the Wrangler JL — Exclusive slantback silhouette delivers a factory-inspired, aerodynamic look no other aftermarket soft top offers for the JL 2-door.
• 30-oz Triple-Layer Black Twill Fabric — Heavier and more flexible than sailcloth, the premium twill delivers superior cold-weather performance, a softer feel, and a smooth, elegant, wrinkle-free appearance for year-round use.
• Sunrider™ Flip-Back Sunroof — Easily open the front panel from inside the vehicle without removing the entire top. The top arch bar spans the driver seat to keep the top secure even in snow and heavy rain.
• 3-in-1 Versatility: Enclosed / Sunrider / Bikini — Run it fully enclosed as an all-season soft top, flip open the Sunrider for a sunroof experience, or remove all side and rear windows for a classic open-air bikini top configuration.
• Hybrid Zipper / Zipperless Window System — Patented zipperless C-channel technology in key areas allows tool-free window removal, while traditional YKK zippers on the rear panel provide security and a weather-tight seal when closed.
• 40-Mil DOT-Approved Tinted Vinyl Windows — Thick, 18% tinted windows block interior heat, reduce glare, and provide privacy — fully D.O.T.-compliant for legal road use in all 50 states.
• UV & Mildew Resistant Construction — Multi-layer fabric construction resists mildew, maintains its shape across all temperatures, and includes built-in UV inhibitors to prevent fading and premature aging.
• Zippered Interior Storage Pockets — Convenient zippered pockets above the driver and front passenger seats keep small gear, phone, and trail essentials organized and off the floor.
• Works with Factory Doors — Compatible with all factory full and half steel doors, as well as Bestop door kits (sold separately) for a weather-tight seal in any configuration.
• No-Drill Installation — Comes complete with all mounting hardware. No drilling into your Jeep's body panels required.

Fitment & Compatibility

The Bestop Trektop NX Black Twill Soft Top (56862-17) is designed to fit all 2018–2026 Jeep Wrangler JL 2-Door models, including the Sport, Sahara, Rubicon, and Willys trim levels. This top is specifically engineered for the JL platform and is not compatible with JK, TJ, or YJ models. If you have a 2018 model year Jeep, please confirm you have a JL and not a JK before ordering. This top does not fold completely down — it must be fully removed to go completely topless. For full convertible/fold-back capability, see the Bestop Trektop Glide for the JL 2-Door.

Installation

The Trektop NX is designed for a no-drill, bolt-on installation and includes all necessary hardware. Light-to-moderate mechanical skill is required; most owners report an installation time of approximately 2.5–4 hours. Important: For best results, install at an ambient temperature of 72°F or above — colder temperatures can cause the fabric to temporarily contract by an inch or more. Any wrinkling that occurs during storage or transit will naturally smooth out within a few days after installation. Bestop recommends using Bestop Cleaner and Bestop Twill Protectant (sold separately) to maintain fabric performance and longevity.
