TOPTOW Dual Hitch Extension 2 in Receiver Adjustable Length - Durable

In this review of the TOPTOW 64131 dual hitch extension, the bottom line is simple: it is best for drivers who need a heavy-duty, multi-use receiver extender to add clearance and mounting options without modifying the vehicle. The product stands out because it pairs a full-strength bottom receiver rated for towing with a convenient top receiver for accessories, making it a practical choice for towing small trailers or adding a bike rack or cargo carrier. The construction and anti-rattle hardware are the single biggest reasons to consider it.

Key Features

• Dual-use design: The lower receiver accepts a ball mount for towing while the upper receiver provides a dedicated mounting point for a bike rack or cargo carrier, expanding utility without extra fabrication.
• Tow rating: The bottom receiver is rated for up to 4,000 lbs GTW and 400 lbs TW, giving confidence for towing light trailers and small campers within that limit.
• Adjustable length: With a total length of 15 in and three pin-hole positions on the shank, the extender can be set for additional clearance or to fine-tune accessory position.
• Anti-rattle hardware: Anti-rattle nuts and bolts on both receivers reduce movement and noise when mounting racks, carriers, or a ball mount for a smoother ride.
• Corrosion resistance: Built from strong steel and finished in a durable black powder coat, the extender resists rust and stands up to road use.

Who It's For

The TOPTOW dual hitch extension is ideal for owners of Class 3 or Class 4 hitch-equipped trucks, SUVs, and utility vehicles who need extra clearance for trailers, off-road vehicles, or to keep accessories away from the rear bumper. It also suits users who want a dedicated upper receiver for a bike rack or cargo carrier while maintaining a tow-ready lower receiver.

This is not intended for someone who needs maximum towing capacity beyond the listed limits, or for those who expect the top receiver to be used for towing, as the top is explicitly not rated for tow loads. Buyers seeking a one-piece drop or specialized weight distribution solution should look elsewhere.

Pros & Cons

Pros

• Heavy-duty feel and build quality that customers note fits factory hitches without extra modification.
• Good value for adding both towing capability and an accessory mounting point in a single unit.
• Anti-rattle bolts reduce noise and movement, improving ride comfort when hauling accessories.
• Adjustable insertion length provides useful flexibility for clearance and fitment.

Cons

• The top receiver is not intended for towing, which limits some dual-towing configurations.
• The unit does not include a hitch pin, so buyers must provide their own or purchase one separately.

Our Verdict

The TOPTOW dual hitch extension is a practical, cost-effective upgrade for owners who need extra clearance and a dedicated accessory mounting point while retaining a tow-capable lower receiver.

Frequently Asked Questions

Can both receivers be used for towing at the same time?
No. The bottom receiver is rated for towing up to 4,000 lbs GTW and 400 lbs TW; the top receiver is intended only for racks and carriers and is not rated for towing.

Will this fit my Class 3 hitch?
Yes. The extender is compatible with most Class 3 and Class 4 2 in receivers, but confirm vehicle tongue ratings before towing.

Does the product include a hitch pin?
The unit includes anti-rattle nuts and bolts but does not include a hitch pin, so plan to use your own pin or purchase one separately.
