Technical Features
- Billet aluminum shank construction: Reduces overall hitch weight compared to steel alternatives, improving handling during installation and removal.
- 5-1/2″ maximum drop with 1″ adjustment intervals: Allows precise height calibration to achieve a level trailer connection across a wide range of trailer heights.
- Dual ball compatibility (2″ and 2-5/16″): Supports towing capacities of 8,000 lb and 12,500 lb respectively, accommodating a variety of trailer coupler specifications.
- Universal 2″ x 2″ receiver fitment with 5/8″ hitch pin holes: Ensures broad compatibility with standard receiver hitch systems without requiring additional adapters.
- Polished aluminum finish: Provides a corrosion-resistant surface treatment that maintains appearance over extended use.
- Stringent safety testing by CURT: Each unit is tested to rated towing and tongue weight specifications to confirm load-bearing integrity before distribution.
Applications
- Towing trailers that sit at a different height than the tow vehicle’s hitch receiver, requiring a drop to achieve a level connection.
- Correcting improper weight distribution caused by an unlevel vehicle-to-trailer connection, which can contribute to trailer sway.
- Use with any standard 2″ x 2″ receiver hitch equipped with 5/8″ hitch pin holes across trucks, SUVs, and full-size passenger vehicles.
- Applications requiring up to 8,000 lb gross towing weight with a 2″ ball, or up to 12,500 lb with a 2-5/16″ ball.
