Bestop 50723-17 Supertop Ultra Soft Goods Box Black Twill JK 4-Door

The Bestop 50723-17 is the Softgoods/Door component box of the Supertop Ultra soft top system for the 2007–2018 Jeep Wrangler JK 4-Door Unlimited. This box contains the premium fabric elements of the Supertop Ultra — including the top deck, side curtains, and windows — and is sold separately from the hardware frame assembly (50722-01). It is the ideal replacement for owners who already have the Supertop Ultra hardware installed and need to refresh or replace the fabric components only.

The Supertop Ultra soft goods are crafted from Bestop's premium Black Twill fabric, the highest-grade material Bestop produces. This triple-layered 30-oz. twill maintains its shape across all temperatures, resists mildew, and includes UV inhibitors to protect against sun damage and fading over time.

Key Features:

• Premium Black Twill fabric — mildew-resistant, UV-inhibiting, and shape-retaining in all climates
• Four operating configurations — fully enclosed, Sunrider open, Safari-style bikini, or fully retracted
• Combination zipper and zipperless channel window system — seamless window installation and removal
• Traditional square-back profile — consistent with the classic Jeep Wrangler silhouette
• Enhanced Sunrider sunroof panel — opens to bathe all passengers in fresh air without removing the full top
• Top fabric folds smoothly and neatly behind the rear seats when fully retracted
• Compatible with Bestop's patented Guide-Track and Lift Assist hardware system (sold separately as 50722-01)

This softgoods-only box pairs with the Bestop Supertop Ultra hardware box (MPN: 50722-01) to form the complete Supertop Ultra kit (MPN: 54724-17). Installation difficulty is rated Moderately Difficult (Level 3) with an estimated installation time of approximately 4 hours. The Supertop Ultra carries a Limited Lifetime Warranty.
