StarknightMT RZR Cup Holder is a bolt-on dual drink mount that fits square passenger grab bars on many RZR UTVs, holding two 18–40oz bottles securely.

Keep beverages within easy reach on off-road rides with a rugged, no-drill cup holder engineered for Polaris RZR square passenger grab bars. Built from heavy-duty steel with a protective powder coat and vibration-reducing rubber inserts, this dual holder fastens to the existing grab bar using a bolt-on system for a clean, secure install.

Which RZR models and grab bars will this cup holder fit?

This holder is designed specifically for square-profile passenger grab bars used on many Polaris RZR variants. It fits a broad range of RZR models that use the square grab bar; it is not compatible with circular or tubular bars.

• Compatible with multiple RZR XP, S, Turbo, Trail, and 570/900/1000 series models using a square passenger grab bar.
• Not suitable for round or aftermarket tubular grab bars.
• Verify your machine’s grab bar cross-section matches a square profile before purchase.

How much and what size cups or bottles can it hold?

The holder accepts common drink containers used on the trail by fitting most 18–40 ounce bottles and tumblers. The opening and depth combine to secure taller drinkware while keeping it accessible for passengers.

• Opening diameter approximately 95 mm to fit popular insulated bottles and tumblers.
• Depth about 86 mm to support taller containers and reduce tipping.
• Dual positions accommodate two drinks at once for convenience on longer rides.

What materials and features make it durable and quiet on rough trails?

Constructed from heavy gauge steel with a black powder-coat finish, the mount resists impacts and corrosion common in off-road environments. Rubber padding at the contact points cushions cups and cuts down on rattle so beverages stay in place during bumpy sections.

• Heavy-duty steel body for structural strength and impact resistance.
• Powder-coated finish for corrosion and abrasion protection.
• Rubber-lined openings reduce noise and protect drink surfaces from scratches.

How simple is installation and what tools are required?

Installation uses a bolt-on clamp design that attaches to the square grab bar without cutting or welding. It includes two mounting positions and should be tightened with proper tools to prevent forward tilt or slipping.

• No drilling or permanent modification to the grab bar required.
• Requires basic hand tools—wrenches or sockets—to torque mounting bolts securely.
• Two possible mounting orientations for user preference and fitment.

Who is this for: Riders who want a durable, easy-to-install drink solution for passengers on Polaris RZR vehicles with square grab bars. It’s ideal for owners who carry insulated bottles or tumblers, need a stable dual-holder for two drinks, and prefer a bolt-on accessory that minimizes noise and protects drinkware during rough off-road use.
