TOPTOW 1-1/4" to 2" Trailer Hitch Receiver Adapter — 6-1/4" Extension, 350 lb Tongue Capacity

TOPTOW's 1-1/4" to 2" hitch receiver adapter converts a smaller Class I/II receiver into a 2" receiver and provides a 6-1/4" extension for easier use of 2" accessories.

This heavy-duty adapter solves a common compatibility problem for owners of compact trucks, SUVs and utility vehicles that come with 1-1/4" receivers but need to use standard 2" accessories like ball mounts, bike racks or cargo carriers. Built from welded steel with a corrosion-resistant powder coat, the adapter is sized and rated for tongue loads (350 lb limit) and is intended for accessory mounting — not for towing trailers.

How does this adapter let me use 2" hitches on a 1-1/4" receiver?

The adapter slides into your existing 1-1/4" receiver and accepts a 2" shank, effectively converting the smaller opening into a standard 2" receiver. It provides a solid, all-welded connection that aligns accessory pin holes for secure attachment.

• Accepts standard 2" shank accessories like ball mounts and cargo carriers
• Fits a 1-1/4" vehicle receiver tube for quick installation
• Uses standard hitch pin holes for secure fastening

What are the size and strength limits I need to know?

The adapter's key dimension is a 6-1/4" center-to-center distance from the vehicle receiver pin hole to the accessory shank pin hole. Construction is heavy-duty steel with a powder coat finish, but the adapter is not designed for towing — only for carrying accessory tongue loads up to 350 pounds.

• 6-1/4" extension length from receiver pin center to shank pin center
• Rated for trailer tongue weight up to 350 lb — do not use for towing trailers
• All-welded steel body with rust-resistant powder coating

Will installation be straightforward and safe?

Yes — installation is simple and requires no special tools beyond a hitch pin or locking pin (sold separately). Make sure to confirm the adapter dimensions match your intended accessory and always observe the tongue weight limit to maintain safe operation.

• Slide adapter into 1-1/4" receiver, align pin holes and secure with hitch pin
• Verify accessory shank size and pin alignment before loading
• Inspect mounting and finish periodically for corrosion or wear

Can I use this for bike racks, cargo carriers, or ball mounts?

This adapter is ideal for non-towing accessories sized for 2" receivers: bike racks, cargo trays, and ball mounts used with bike carriers or cargo platforms. Because it increases reach by 6-1/4", consider clearance and loading angles to avoid interference with vehicle bumpers or lights.

• Recommended for bike racks, cargo carriers, and accessory mounts
• Not for towing trailers; observe the 350 lb tongue weight limit
• Check vehicle and accessory clearances after installation

Who is this for: TOPTOW's 1-1/4" to 2" 6-1/4" adapter is best for drivers who own vehicles with Class I/II 1-1/4" receivers but want to use widely available 2" accessories. It fits DIYers, weekend adventurers, bike owners and small utility users who need a rugged, simple converter for non-towing loads. Always measure your receiver, confirm accessory dimensions, and respect the tongue weight rating when choosing this adapter.
