Bestop Trektop Soft Top

2004–2006 Jeep Wrangler TJ Unlimited 4.0L I6

Part #: 56821-35

Overview

The Bestop Trektop Soft Top in Black Diamond is a versatile and stylish replacement soft top designed specifically for the 2004 to 2006 Jeep Wrangler TJ Unlimited with the 4.0L inline-six engine. Renowned for its distinctive fastback styling, the Trektop offers a sleek, aerodynamic profile that enhances the classic Jeep look while providing excellent weather protection. This soft top is perfect for Jeep enthusiasts who want a combination of style, convenience, and functionality without the bulk of traditional frame-supported tops.

Unlike conventional soft tops that require multiple bows and frames, the Trektop utilizes the Wrangler’s existing sport bars for structural support and shape, simplifying installation and reducing clutter. Its innovative design allows you to remove the rear and side windows easily, transforming the top into a Safari Bikini style for open-air driving enjoyment. This dual-functionality makes the Trektop a practical choice for drivers who want flexibility in their Jeep’s configuration.

Construction & Design

The Trektop Soft Top is crafted from Bestop’s signature Black Diamond fabric, known for its rugged durability and resistance to UV rays, water, and mildew. The material maintains its rich black color and structural integrity even after extended exposure to harsh outdoor conditions. Reinforced stitching and heavy-duty zippers ensure the top withstands daily use and off-road adventures alike.

The design eliminates the need for cumbersome top bows by relying on the Jeep’s sport bars for support, which not only simplifies installation but also reduces weight and wind noise. The fastback profile improves airflow over the vehicle, contributing to a quieter ride compared to traditional soft tops with bulky frames.

Installation & Fitment

Installation of the Bestop Trektop Soft Top is straightforward and requires no modifications to the vehicle. The top is engineered to fit perfectly on 2004 to 2006 Jeep Wrangler TJ Unlimited models equipped with the 4.0L I6 engine. It attaches securely to the factory sport bars, eliminating the need for additional bows or frames. The pre-attached windows and reinforced mounting points make the process quick and hassle-free, allowing you to upgrade your Jeep’s top in just a few hours with basic hand tools.
