CURT 2" Receiver Extender 8" Length – 2x2 Heavy-Duty Hitch Extension, 3,500 lb GTW, Gloss Black

The CURT 45791 is an 8-inch, 2"x2" receiver extender that increases clearance for hitch-mounted accessories while carrying up to 3,500 lb gross trailer weight and 350 lb tongue weight.

If a bike rack, cargo carrier, spare tire or trailer coupler sits too close to your bumper, the CURT 45791 receiver extender creates the space you need without permanent modification. Built from CNC-formed steel and robotically welded for consistent fit, this 8" extender slips into any standard 2" receiver to move your accessory rearward. A gloss black powder coat protects the tube from corrosion and chips for long-term use on road, trail or worksite.

How does this extender solve clearance problems?

By inserting the CURT 45791 into your existing 2" receiver, you gain an additional 8 inches of horizontal clearance between the hitch-mounted accessory and your vehicle. That extra distance reduces contact risk with bumpers, spare tires, and rear sensors, and it helps keep cargo carriers and bike racks level.

• Adds 8" of spacing for rear-mounted accessories
• Prevents bumper scuffs, dents and interference with spare tires
• Makes attaching trailers or accessories easier and more secure

Will this extender handle the weight of my trailer or rack?

The CURT 45791 is rated for a gross trailer weight of 3,500 lb and a tongue weight of 350 lb, matching many light-duty towing and accessory needs. Always verify your vehicle, hitch receiver and accessory capacities before use to ensure safe towing and load distribution.

• 3,500 lb gross trailer weight rating
• 350 lb tongue weight rating
• Matches common bike racks, cargo trays, and small trailers when within rated limits

How is this extender built to last in outdoor conditions?

CURT manufactures this extender with precision processes—CNC forming, robotic welding and mechanical descaling—to ensure a precise fit and consistent strength. A gloss black powder coat finish resists rust, chipping and UV damage so the extender remains functional and presentable season after season.

• CNC-formed steel for accurate dimensions
• Robotically welded seams for uniform strength
• Durable powder coat to protect against corrosion and abrasion

How do I install and secure the 45791 extender?

Installation is straightforward: slide the extender into a standard 2" x 2" receiver and align the hitch pin holes, then insert a hitch pin or locking pin (sold separately) to secure it. Double-check pin tightness and perform a quick walk-around to confirm clearance and alignment before towing or loading accessories.

• Insert into standard 2" x 2" receiver tube
• Align holes and secure with hitch pin or lock (not included)
• Inspect fit and clearance before each trip

Who is this for? The CURT 45791 2" receiver extender is ideal for drivers who need a reliable way to increase rear clearance for bike racks, cargo carriers, or light trailers—particularly owners of SUVs, trucks and vans with spare tires or rear bumpers that limit accessory placement. It's also a practical choice for DIYers and small-business owners who value precision-built towing accessories and want a corrosion-resistant extender backed by CURT's limited lifetime warranty for parts and an initial finish warranty.
