Video Transcript for Review of Curt Hitch Adapters - Hitch Reducer - C45770

Today we're going to take a look at the Curt trailer hitch receiver adapter. Now this is going to reduce your two-inch hitch down to an inch and a quarter to work with your inch and a quarter accessories. This is going to fit class three hitches only. With that two inch by two inch receiver and then again unless you use the other side for your inch and a quarter accessories like a bike rack or cargo carrier. Now one thing to keep in mind with this is that it is going to reduce your hitch's weight capacity by 50% or by half, so you don't want to use this in a towing application or for new snow plow attachments.Our receiver adapter is going to be made of a steel construction with that solid two inch shank. It has a nice gloss black powder coat finish, helps to resist any rust or corrosion.

It does not come with a hitch pin or clip, so you will have to use the accessories that you already have or pick one up here at etrailer.com. It's going to have a little bit of an extended length to allow your accessory to be mounted a little bit further from your hitch. Overall, it's nine inches from end to end, and the distance between our hitch pinholes is going to be four and a half inches center to center. That's going to do it for our look at the Curt trailer hitch receiver adapter.

The adapter is pretty straight forward. I am writing this review because I wish I had called and spoken to someone when I first bought the hitch. I bought the hitch (no shipping charges), then realized I need an adapter. I paid shipping charges for the adapter and then realized I really wanted anti-vibration, locking pins (more shipping charges). This is no reflection on etrailer, they're great. But there is a lesson to be learned from my lack of forethought. 662940

This is a simple product that allows you to use 1 1/4 inch receiver mount in a 2 inch receiver. I'm using it for mounting a ATV winch receiver mount in the front receiver on my pickup truck. As with all steel Curt products it is very well made and seem to have powered coating to make it last a long time; time will tell. 652502

Not much to say - it is as advertised and fits 2" to 1 1/4. Seems well made. 640955

I used this to attach hitch-mounted bike rack to a newly-installed front hitch. It takes the bike rack out beyond the bumper and grill, leaving plenty of clearance. 669807

Bike rack is 1 1/4 inch and I needed this adapter to put it into my 2" hitch receiver. Adds a little distance to keep the bikes away from the back of my Jeep. 707399

The hitch pin and clip didn’t fit the 2” receiver part to small. It needs a 5/8” x 3” to 31/2” long hitch pin. The other pin sent fits the 11/4” receiver but still to short for clip to go in. Tried to call two different days after receiving order could never get through. 877947

This is exactly what it appears to be. None were available locally, but Etrailer delivered within about a week of my buying. 862852

I wish it were an inch or two shorter. I also had to buy a hitch clamp so the bike rack wouldn't sway. 851605

Excellent Adapter for extending and attaching a Thule bike rack to a 2" receiver. More solid than a Thule sleeve, and the extensions provide ample clearance to open the SUV Rear Door. 820417

Purchased this when I got a new hitch from etrailer for my new car. Made sure I'm ready for any possible hitch situation, and this fit the bill perfectly. Great price, great product. 786516

The 4" adapter is about right for length.......not too short and not too long. Heavy duty construction should bring longevity of use. I don't like the "slop" fit ......but imagine it has to be that way. Ordered bracket to tighten this up to stop movement of the bike rack and for other uses. Would suggest the sales force mention these brackets to make it one purchase, instead of two, if people want to tighten up the fit. The adaption from 2" to 1 1/4" for bike rack is perfect. Company sells several options for stopping the rattles and sway. 776913

Ask the Experts about this Curt Hitch Adapters

  • Hitch Pins for Use with Curt Trailer Hitch Receiver Adapter # C45770
    Hitch pins are not included with the Curt Trailer Hitch Receiver Adapter # C45770. The reason they aren't is that not everyone needs a hitch pin so instead of forcing people to pay extra for a part they may not need it's offered separately. For the 1-1/4 inch portion of the adapter the pin and clip you'd need is the part # F-4 and then for the 2 inch portion you'd want the part # PC3.

  • Anti-Rattle Device for 2 Inch to 1-1/4 Inch Receiver Adapter Carrying Bike Rack
    Because using an adapter like the # C45770 adds another piece to the connection between the hitch receiver tube and the hitch mounted accessory (bike rack in this instance), you will tend to get some more movement than you normally would. If you were to use a Roadmaster Quiet Hitch, part # RM-061 where the adapter connects to the receiver hitch, it would prevent movement there. If your bike rack already has an anti-rattle threaded hitch pin, you won't need to do anything about the connection...

  • Recommended Trailer Hitch Adapter Compatible with Thule T2 9045 Bike Rack and 2 Inch Receiver
    For your Thule T2 Classic 2 Bike Platform Rack - 1-1/4" Hitches # TH9045 there is not a an adapter compatible for a 2 inch hitch from Thule and they also don't have the replaceable shank to upgrade to the 2 inch receiver. The best adapter to fit your truck is the Curt Trailer Hitch Receiver Adapter - 2" to 1-1/4" - 4" Long # C45770. This will allow you to use the hitch lock that came with your bike rack and then you will use a separate hitch lock like # 63232 to secure and lock the...

  • Trailer Hitch for 2020 Ford Escape Hybrid
    I am happy to help you find a hitch for your 2020 Ford Escape Hybrid. I contacted Draw-Tite to discuss the # DT92RR hitch, and they are currently researching its compatibility with the Hybrid model after discovering issues with fitment near the exhaust. I recommend you go with the Curt # C23FR hitch. It is a confirmed fit for the Hybrid and there are some helpful customer reviews showing it installs and works well on your vehicle. The Curt hitch is a 2 inch instead of a 1-1/4 which...
