by:

This unit fits the hitch on my 2022 F250 perfectly. It's nice the holes line up and the adapter sleeves have stop tabs that keep them from sliding inward as you install your receiver hitch.



by:

This was exactly what I needed to adapt my F250 trailer hitch (3”) to the bike rack (2”) that I also bought through etrailer. The sales reps were great to deal with, they were knowledgeable, efficient, polite and personable. Both items arrived earlier than the predicted arrival date. I’m very impressed with eTrailer, this won’t be my last order with this company.



by:

The item is exactly what we needed. It arrived safely and on time. Your service is outstanding and you are my first "go to" when I need parts and accessories for our trailer. Thank you for all your hard work keeping this business going.



by:

Had to reduce my hitch receiver from 3” to 2”. This worked perfect. Shipping was super fast. Great people to work with. Keep in mind if you’re using an old 2” receiver hitch pin you need to buy a longer one that will accommodate the 3” receiver.



by:

Serves its purpose.


Comments
Cant haul or fly my FREEDOM flags without it.
Princess K - 04/30/2022

by:

Works as advertised. E-trailer found this as an alternative to a different sleeve I had purchased that would ship mush later. This gives more functionality at a cheaper price than what I had been looking at.



by:

Quality product to fit the needs of a 2" hitch in a 3" receiver for the new F350s. Good service and prompt delivery.



by:

This adapter was exactly what I needed. My 2019 F350 has a 3" receiver. I only own 2" hitches. This solved the problem. I had originally bought a similar sleeve at a Ford dealership. It did not work because of a design flaw which was an unnecessary lip that blocked the hitch from fulling seating in the sleeve. Etrailer has solved another issue for me that included the exact part for the job. Thank you.



by:

Bought this for my 2020 Ford 350 XLT. It fit like a glove. The nipple on the 2" reducer makes hooking my hitch SO much better than the one I was currently using. It is very frustrating to line up 2 or more moving parts. I highly recommend this for anybody with a Ford Superduty truck.


Comments
Still 5 stars
John M - 04/30/2021

by:

New F350 came with a 3" hitch and almost all my hauling stuff 2" draw bars, so this seems to be solution. Heavy duty and well made. Had shipping nightmare that was not etrailers fault. Took over a month to receive product.



by:

Very nice fit in my 2019 F250 with a 3" receiver. Can't say enough good about the customer service I received from eTrailer, their help finding the right product was superb!



by:

So far so good. The real test will be when we hook up the trailer to tow.



by:

I just received these but haven't used them yet. They appear to be heavy duty and are solidly built. I expect they will work well.



by:

Worked great, my Ford 2020 F350 came with a 3" receiver hitch. This adapter provided exactly what I was looking for for both a 2 1/2" and 2" hitch hookup. I could not get this type of adapter from Ford, not available.



by:

I got this reducer to attach my 2 inch rock tamer mud flaps to the 3 inch receiver on a truck. The adapter does reduce from 3" to 2.5 " to 2". However, the reducers from on size to the next are not anywhere near snug. The rock tamers wobble a lot.

The adapter will work, but realize there will be considerable slop.



by:

This product works exactly as described and intended for. Makes the three inch receiver on the F350 much more compatible with the various hitches around the garage. No issues and can definitely put it into the recommended column.



by:

It fit my F450’s 3” hitch perfectly and the shipping was fast!



by:

The inserts fit into the receiver and line up well when setting up. The stops on the inserts are spot-on. The inserts would perform better, however, if they extended the length of the receiver tube. Being so short, they allow some play in the hitch assembly.



by:

This was a much-needed accessory for my 3-inch receiver hitch. I have been looking everywhere and finally found this setup on etrailer. The fit is perfect and the price is very reasonable. Plus you really get two adapters in one. The larger one reduces from 3 in to 2 1/2 in and the smaller insert slides in to take it down to a 2 in. This one adapter will allow you to use virtually all your hitch accessories with your 3 in receiver.



by:

It fit great, easy to install



by:

Delivered as promised. Works like it's supposed to.



by:

This hitch adapter works great on my 2020 F-250. I have seen forums where people complain about the fitment of other adapters. This one doesn't move around and gets the job done. Great product.



by:

Tried out the reducers this morning and they fit perfectly. They are of good quality and good appearance. The reducers are needed so I can pull several sizes of trailers .


Comments
The reducers are working real well. They are of good quality and holding up well. I would recommend the reducers if they are required. I dont let them in all the time to help preserve the finish on them. Good quality good product.

etrailer was very helpful ups lost item co replaced it very quickly used on 2014 ram 2500 with a 3” receiver item is made very well pull a large dump trailer and a 30’ cabin cruiser 700 miles round trip thanks very much mike



by:

If you are tired of your adapters falling back in your hitch every time you attempt to insert your hitch PIN then this is the right solution for you. I bought this for my 2020 F250 so I could use my 2 inch hitches and it works perfectly. The hitch pin lines up better and these adapters will not slide and disappear back in the hitch. Highly recommend.

  • 3 Inch to 2 Inch Hitch Receiver Adapter
    We have what you need. It is the Curt Reducer Sleeve # C45408. This adapter reduces a 3 inch hitch receiver to a 2-1/2 or 2 inch receiver opening. I've linked a video for you.

  • Trailer Hitch Receiver Adapter from 3 Inch to 2 Inch Opening
    Yes, the Curt Hitch Receiver Reducer Sleeves part # C45408 will allow you to use a 2" shank inside a 3" trailer hitch receiver opening. This reducer has a carbide black powder coat finish which will reduce the chance of rust and it has a limited lifetime warranty. I have attached a review video on the above adapter for you as well.

  • Why Do Curt Hitch Receiver Reducer Sleeves # C45408 Only Have One Hitch Pin Hole
    The Curt Hitch Receiver Reducer Sleeves # C45408 only has one hitch pin hole per sleeve as it is not designed to be a hitch extender and protrude out of the hitch opening. The sleeves are designed to fit flush in the hitch they are installed in.

    The distance from the front face of the Curt # C45408 Reducer Sleeve to the center of the hitch pin hole is 2-1/2 inches, as indicated int he photo I've provided.

  • Pin Hole Size for the Curt Hitch Receiver Reducer Sleeves # C45408
    Both of the pin hole diameters for the Curt Hitch Receiver Reducer Sleeves # C45408 that you referenced are 3/4 inch. Since your hitch's pin hole is larger at 5/8 inch you could just go with a 3/4 inch pin like what this fits like part # 58388 and you'd be set.

  • How To Use Weight Distribution Hitch With A 3" Hitch Receiver On 2021 Ford F-250 Super Duty
    I do have a solution for you, however, there currently is not a 3" shank available for a weight distribution system. You will need to use a reducer sleeve such as Curt Hitch Receiver Reducer Sleeves # C45408, which will reduce a 3" receiver to 2-1/2" or 2". This has been confirmed to work with weight distribution systems and will NOT reduce your towing capacity. This is your best route if you want to use your current weight distribution hitch with your 2021 Ford F-250 3" hitch receiver....

  • Can You Use a 5/8" Hitch Pin On 3" Hitch with 3/4" Hitch Pin Hole
    If the trailer hitch has a 3/4" diameter hitch pin hole then that is what you'll need to use when towing with said hitch even when using an adapter such as the Curt Hitch Receiver Reducer Sleeves part # C45408. If you don't have a 3/4" diameter hitch pin we do offer the Super Titan Trailer Hitch Pin and Clip part # 58388. There would be too much slop with the smaller pin to be safely used inside the larger opening.

  • Reducer Sleeve to Install Weight Distribution System in 3-Inch Hitch
    Weight distribution shanks like Curt part # C17123 are available in 2-inch and 2-1/2-inch hitch sizes but not 3-inch. But to use your system in a 3-inch hitch all you need to do is use a reducer sleeve # C45408. This reducer will allow 2-inch and 2-1/2-inch shanks to fit your 3-inch hitch.

  • Sleeve Adapter Recommendation for Converting 2 inch Hitch Size to 1-1/4 inch
    We have the sleeve adapter part # HT02 which is designed for allowing a 1-1/4 inch hitch accessory to fit in a 2 inch trailer hitch. Some bike racks have specific adapers made for them but this adapter works for most. Feel free to email me back with what bike rack you have and I can see if we have an adapter specific for it.

    The MaxxTow Hydraulic Pickup Truck Crane for 2inch Hitches - 1,000 lbs Item # MT70238 that you referenced is designed to fit a 2 inch hitch opening. If you wanted it to fit a 3 inch trailer hitch you'll want the part # C45408. This will fit your 3 inch hitch and give you a 2 inch hitch for the Crane to install in.

  • Can Hitch Reducer Sleeve Be Used with Weight Distribution Shank Without Loss of Capacity
    We offer weight distribution shanks for 2-inch and 2-1/2-inch hitches, shown on the linked page, but not one for a 3-inch hitch. We can still help you. Adding Curt reducer sleeve # C45408 allows dropping a 3-inch receiver down to either the 2-1/2-inch size to allow use of a Reese shank like # RP54977 or to a 2-inch size, which would allow you to continue using your existing 2-inch shank. This reducer does NOT cause a loss of hitch capacity the way other types of adapters do. Hitch extenders...

  • Reducer Sleeve Needed for Diversi-Tech 2
    If you have a 3 inch receiver opening on your 2017 Ford F-350 and you want to utilize both a 2-1/2 inch receiver and 2 inch receiver then the perfect solution for you is the Curt Reducer # C45408. This is compatible with a 3 inch receiver and reduces it to 2 inches for your application. This will allow you to use your Diversi-Tech 2 inch ball mount with the hitch receiver on your F-350.

  • Recommended Trailer Hitch Adapter for 3 Inch Hitch Receiver Opening
    To convert a 3 inch receiver opening to a 2 inch receiver accessory you will need a hitch adapter. If you are just using a ball mount I recommend the Curt Hitch Receiver Reducer Sleeves - 3" to 2-1/2" or 2" # C45408. If you are going to be using an anti-rattle device like you'd want on a ball mount I recommend instead using the Reducer Sleeve for Super Titan Hitch Receivers - 3" to 2" # 38735. This will allow you to use an anti-rattle lock on the 3 inch receiver and then use the anti-rattle...

  • Recommended Trailer Hitch Adapters And Lock For Super Titan 3" Trailer Hitch Receiver
    For your Super Titan 4000 Weld-On Trailer Hitch with 3" Receiver # 38124 I recommend using the Curt Hitch Receiver Reducer Sleeves # C45408. These sleeves can both be used at the same time to reduce your 3" receiver to a 2" receiver. And if you ever find the need for a 2-1/2" receiver you can use just the one large sleeve for that hitch. Both sleeves have a 3/4" pin hole for accepting your larger pin. The Draw-Tite Trailer Hitch Receiver Lock # 63259 is designed for 3" receivers and has...

    The pin in the Anti-Rattle Hitch Lock and Cable for Swagman Bike Racks # S64030 measures 4-1/2" from the lock piece to the head of the bolt which should be enough room for a 3" receiver and the cable lock but it would be best for you to double check on your end. Please note that you do need to use a reducer sleeve for this rack because if you were to use it as-is you would have about 1/2" of gap all around the shank. For your application I recommend using the Curt Hitch Receiver Reducer...

  • Adapter Needed to Use 1-1/4 Inch Bike Rack in 2 Inch Receiver Hitch
    It sounds like you're needing a reducer sleeve. A reducer sleeve like # HT02 will allow you to use your bike rack that's designed for a 1-1/4 inch receiver in the 2 inch hitch on your vehicle. The # C45408 that you'd looked at is a similar item, but it's not designed to reduce a 2 inch receiver to a 1-1/4. If you click the provided link, you can see a product demonstration video.

  • How to Use Blue Ox Weight Distribution in 3 Inch Hitch
    While there is not a 3 inch shank available for a Blue Ox weight distribution system like the Blue Ox SwayPro # BXW1500, a reducer is definitely a viable option that is just as safe and will work really well. The best option for this is a reducer sleeve that fits inside your 3 inch receiver as opposed to an adapter that sticks out of the hitch, and for that you will need the Curt Hitch Receiver Reducer Sleeves - 3" to 2-1/2" or 2" # C45408. This will just slide into your hitch so there...

  • How to Use Roadmaster RoadWing on 2015 Chevy Silverado 3500 with 3 Inch Receiver
    As long as the ball mount that you're using is a 2" then you can use the Roadmaster RoadWing Removable, Expandable Mud Flap System for RVs, Buses and Dual-Tire Trucks # RM-4400-102 without any issues. These mudflaps do not connect directly to the receiver so you should be able to make this work on your 2015 Chevy Silverado 3500. If you don't have a 3" to 2" reducer sleeve you can use the Curt Hitch Receiver Reducer Sleeves - 3" to 2-1/2" or 2" # C45408. I've linked our entire selection...

  • Can I Use the Reese Steadi-Flex # RP66560 with the Curt Shank # C17132 on My Ford F-350's 3" Hitch?
    Yes, the Reese Steadi-Flex Weight Distribution System w/ Sway Control # RP66560 will work with the Curt Weight Distribution Shank # C17132 on your 2020 Ford F-350. However, in order to use the Curt shank, you will need a hitch reduced on your 3-inch hitch in order to fit the 2-1/2 shank into your receiver. For a reducer, I recommend the Curt Hitch Receiver Reducer Sleeves - 3" to 2-1/2" or 2" # C45408. The installation is easy to use and slides directly into your hitch or onto the Curt shank.

    I do have a solution for you but unfortunately we don't have any hitch extenders that fit the 3" receiver on your 2017 Ford F-350 and are at least 24" long. What you could do is use the Curt Hitch Receiver Reducer Sleeves # C45408 to go from 3" to 2-1/2" and then utilize the Curt Hitch Extension and Reducer # C45048 which goes from 2-1/2" to 2". This extension can be used in either the 34" or 24" length by cutting the shank itself. At the 24" length it has a max gross trailer weight (GTW)...

  • Recommended Hitch Receiver Reducer for 2017 Ford F-250 with 3 Inch Hitch to Blue Ox Sway Pro System
    For the traditional Blue Ox Sway Pro, you will need the Curt Hitch Receiver Reducer Sleeves - 3" to 2-1/2" or 2" # C45408 to reduce a 3 inch receiver down to 2 inches. This is not rated for a specific weight rating because it does not protrude from the hitch opening. Another option is to use the Buyers products # 337RTA302 which has one less moving part and are rated for tongue weights up to 1,200 lbs.

  • Availability of 3 Receiver to 2 Weight Distribution Shank Adapter with Anti-Rattle
    Since you want to avoid an adapter that uses 2 sleeves to get you from your 3" receiver down to the 2" shank size of your weight distribution (WD) system you can potentially use either the 12K Reese Titan # 38735 or the 12K Buyers Products # 337RTA302. The Reese Titan is not compatible with Ford OEM 3" receivers though so if that's what you have then you can't go with this product. It's only designed to work with the Reese Super Titan hitches.

  • Is There A Weight Distribution System Shank That Can Work In A 3" Receiver?
    There are no weight distribution shanks that fit into a 3" receiver, however I do have a workaround. I recommend using a reducer sleeve, like the Curt Hitch Receiver Reducer Sleeves # C45408, which will allow you to use a 2" or 2-1/2" WDS shank in your 3" receiver. From here, you can use the Equal-i-zer Weight Dist Shank # EQ90-02-4600. This shank is 18" long, has 8" of rise, and 4" of drop. This shank has a maximum tongue weight capacity range, of 600-lbs-1,400-lbs.
