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

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

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

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

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

  • 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.

  • 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.
