Construction & Design

Bestop’s replacement quarter window is engineered using premium black vinyl fabric paired with a clear, flexible window material that resists cracking and yellowing over time. The vinyl is designed to match the factory soft top’s texture and color, ensuring a consistent appearance. The window is precision-cut and heat-sealed to provide a tight, weatherproof seal against the elements.

Special attention is given to the corner stiffener, a critical structural component that must be transferred from the original window to the replacement. This design consideration helps maintain the window’s shape and fitment, preventing sagging or distortion during use.

Installation & Fitment

Installation is straightforward for anyone familiar with soft top maintenance. The replacement window is designed to fit perfectly into the existing soft top frame of 4-door Jeep Wrangler JL models from 2018 to 2025. When replacing the window, it is essential to remove the factory corner stiffener from the original window and reuse it in the new one. Bestop includes clear, step-by-step instructions to guide you through this process, ensuring a secure and professional installation without the need for additional tools or modifications.
