CURT 2" Receiver Extender — 8" Length (2x2) Black, 3,500 lb GTW & 350 lb TW

The CURT 45791 is a 2" x 2" receiver extender that adds 8" of clearance to your hitch while supporting up to 3,500 lb gross trailer weight and 350 lb tongue weight.

If your bumper, spare tire, or a hitch-mounted accessory is too close to a trailer or cargo carrier, the CURT 45791 gives you reliable extra room so you can tow and carry gear without contact or interference. Built from CNC-formed steel with robotic welds and a gloss black powder coat, this extender is engineered to resist rust and deliver a consistent fit in 2" receiver openings.

How does this extender create the clearance I need?

The CURT 45791 slides into a standard 2" receiver and lengthens the hitch opening by 8", moving accessories and trailer couplers farther from the vehicle. That extra distance reduces the chance of bumping into bumpers, spare tires, or rear-mounted racks during hookup and while driving.

• 8" added length for more space behind vehicle
• Fits 2" x 2" receiver tubes for broad compatibility
• Prevents contact between cargo/tow gear and vehicle surfaces

Will this affect towing capacity or safety?

When used properly, the extender maintains a gross trailer weight rating of 3,500 lb and a tongue weight rating of 350 lb. Always follow vehicle and trailer manufacturer's guidance: extenders can change leverage on the hitch, so confirm capacity and use correct hitch pins and safety chains for safe towing.

• 3,500 lb gross trailer weight (GTW) rating specified by manufacturer
• 350 lb tongue weight (TW) rating for mounted accessories or trailers
• Use with appropriate hitch hardware and safety chains for compliance

What makes the CURT 45791 durable and corrosion resistant?

This extender is CNC-formed for precise dimensions, mechanically descaled to prepare the steel, then robotically welded for consistent strength. A glossy black powder coat finish shields the steel from rust, chips, and UV exposure for long-lasting appearance and performance.

• CNC-formed and mechanically descaled for accurate fit
• Robotically welded joints for consistent structural strength
• Gloss black powder coat to resist corrosion and surface wear

How easy is it to install and remove?

Installation is a simple insert-and-pin process: slide the extender into the 2" receiver, align the hitch pin holes, and secure with a pin and clip (or locking pin). Removal follows the same straightforward steps, making it convenient to add clearance only when needed.

• Simple insert-into-receiver design for quick mounting
• Compatible with standard 2" hitch pins and locking pins
• Portable and reusable across compatible vehicles and racks

Who is this for: The CURT 45791 2" receiver extender is aimed at drivers who need reliable extra clearance for trailers, bike racks, cargo carriers, or vehicles with rear-mounted spare tires. It's suited to DIYers, weekend boaters, and anyone who wants a durable, precise-fitting steel extender that resists weathering while preserving rated towing limits when used correctly.
