CURT 2" x 2" Receiver Extender 8" — 3,500 lb GTW, gloss black powder coat

CURT 45791 is a heavy-duty 2" x 2" receiver extender that adds 8" of clearance to your hitch and is rated for 3,500 lbs gross trailer weight and 350 lbs tongue weight.

If your bike rack, cargo carrier or trailer coupler needs more room from your vehicle's bumper, spare tire or rear sensors, this CURT receiver extender creates the space you need without altering your original hitch. Built from CNC-formed steel and robotically welded, the extender is finished in gloss black powder coat for long-term resistance to rust, chipping and UV exposure. It's meant to be a straightforward, durable solution for common spacing conflicts when towing or mounting accessories.

How much extra space does this receiver extender provide?

The CURT 45791 increases the distance between your hitch and accessory by 8 inches, giving additional clearance for rear-mounted gear or trailer coupler alignment. That 8" extension is measured from the original receiver opening to the extender's outer tube.

• Adds 8" of usable receiver length to a 2" x 2" hitch
• Makes room for spare tires, bumpers and rear-mounted accessories
• Helps prevent contact, scuffs and dents to vehicle finishes

What towing capacity and tongue weight can I expect?

This model carries a gross trailer weight (GTW) limit of 3,500 lbs and a tongue weight (TW) capacity of 350 lbs when used correctly. Those ratings are suitable for many light trailers, cargo carriers and multi-bike racks, but always confirm combined system capacities and vehicle limits before towing.

• Rated 3,500 lbs gross trailer weight
• Rated 350 lbs tongue weight for mounted accessories
• Match with vehicle and hitch manufacturer's limits for safe operation

What materials and finish protect the extender from wear?

The extender is CNC-formed and robotically welded for consistent geometry and strength, then mechanically descaled to remove weld spatter and improve fit. A durable gloss black powder coat shields the steel from corrosion, chipping and UV, extending service life in outdoor conditions.

• CNC-formed steel body for accurate dimensions
• Robot welding and mechanical descaling for reliability and fit
• Gloss black powder coat for rust and UV resistance

How do I install and secure the CURT receiver extender?

Installation is a simple slide-in process for any 2" x 2" receiver: insert the extender, align hitch pin holes and secure with a properly sized pin and clip or locking hitch pin (sold separately). Ensure you follow torque and installation recommendations and verify that added length does not interfere with lights, sensors or safety chains.

• Slides into a standard 2" x 2" receiver opening
• Requires a hitch pin or locking pin to secure (not included)
• Check vehicle clearance and accessory alignment after installation

Who this is for: The CURT 45791 is designed for drivers who need straightforward extra clearance for hitch-mounted gear or to properly space a ball mount and trailer coupler. It's a practical choice for weekend tow vehicles, SUVs with rear-mounted spare tires, owners of bike racks or cargo carriers, and small-trailer users who stay within the listed weight ratings. If you require more than 3,500 lbs GTW or intend to use the extender with heavy-duty towing, consult vehicle and hitch manufacturers for alternate solutions.
