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.

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.

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.

My RV came equipped with an 3" received that had to be reduced to 2". Works perfectly, it does require a little patience to get all the holes lined up.

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.

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.

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 .

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.

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.

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.

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.

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.

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.

See what our Experts say about this CURT Hitch Adapter
- Recommended 3 Inch to 2 Inch Hitch Reducer with 5/8 Inch Pin HoleThere is a solution for you, the Buyers Products 3" to 2" Receiver Tube Adapter # 337RTA302 which has a 5/8" hitch pin hole and would give you the security you need. Using the Curt Hitch Receiver Reducer Sleeves - 3" to 2-1/2" or 2" # C45408 with its 3/4" hitch pin hole would not be ideal because the conflicting hitch pin diameters would mean your tow bar would be loose inside the receiver. I have added a link to a video review of the Buyers Products adapter for you to check out as well.
view full answer... - What Size Hitch Pin Fits The Curt Hitch Receiver Reducer Sleeve part # C45408?Hi Steve, The Curt Hitch Receiver Reducer Sleeves - 3inch to 2-1/2inch or 2-inch part # C45408 has a pin hole diameter of 3/4". However, since this is adapting all the way down to a 2 inch, you'll need to use a 5/8" pin because the pin hole diameter of a ball mount you want to tow with will be 5/8" in diameter for an accessory that fits a 2 1/2" or 2" hitch. You'll have a small amount of room around the pin hole for the 3 in sleeve, but it will be flush to the pin hole for the 2 1/2"...
view full answer... - Recommended Multipurpose Ball Mount with Receiver for 3 Inch Trailer Hitch Receiver CompatibilityThe Curt Multipurpose Ball Mount with 2" Receiver for Bike Racks and Cargo Carriers - 7,500 lbs # D210 will work with a 3 inch receiver when you use the Curt Reducer # C45408. If you need more adjustability to tow level, then the best option is the Gen-Y Adjustable 2-Ball Mount w/ Stacked Receivers for 3" Hitch - 12" Drop/Rise - 32K # 325-GH-1725 or the 9 inch drop/rise # 325-GH-1724. These assemblies offer stacked receivers that you can use bike racks or other accessories in. This will...
view full answer... - Weight Distribution Hitch for Trailer With 11,495 lb GVWRGreetings Tim; when you choose a WDH you want to go off of the tongue weight of your loaded setup. The best way to find this is to measure with a scale like the # BTBRV44FR. Since you provided the specs for your trailer we can take a guess to help find the right system. Tongue weight is typically 10-15% of the loaded trailer weight. We know your dry tongue weight is 890 lbs. Factor in batteries and propane and you're already adding about 100 lbs so close to 1,000 lbs unloaded. At the high...
view full answer... - Can RHS2 Hitch Stair Be Used With 3" To 2" Hitch Reducer Sleeve?Hello Mike, thanks for reaching out. Yes, the # RHS2 Hitch Stair can indeed be used with a 3" to 2" reducer like the Curt # C45408. As long as your hitch reducer is not an extension, they will work together fine. Hitch extensions will lower your tongue weight capacity. The # C45408 is a reducer sleeve that inserts fully inside the hitch, so no tongue weight capacity reduction. Those sleeve adapters can create a bit more play at the hitch, but that is the only thing you would need to keep...
view full answer... - Recommended Hitch Reducer For A 3" Trailer Hitch ReceiverHey Gerry, The Buyers Products 3" to 2" Receiver Tube Adapter # 337RTA302 uses a 5/8" hitch pin, but I'm assuming you probably have a 3/4" hitch pin hole on your 3" receiver? If so then the Curt Hitch Receiver Reducer Sleeves - 3" to 2-1/2" or 2" # C45408 would be a better option for you help eliminate play.
view full answer... - Recommended Hitch Extender for Towing/Hitch Accessories With Truck Bed CamperBoth the Curt # C45048 and the Reese # RP45292 hitch extensions would require using a 3 inch to 2-1/2 inch reducer sleeve # BWRHXA2183. This would work pretty well for towing but it would allow a hitch mounted accessory like a bike rack to bounce about quite a bit which would concern me. The bouncing force would increase the leverage applied to the extender and the hitch installed on the truck, so I'm not thrilled with either of those two solutions. I'd prefer to see you use an extender...
view full answer... - Can You Use a 5/8" Hitch Pin On 3" Hitch with 3/4" Hitch Pin HoleIf 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.
view full answer... - How To Use Weight Distribution Hitch With A 3" Hitch Receiver On 2021 Ford F-250 Super DutyI 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....
view full answer... - Recommended 12k Winch And Mounting Plate For A Trailer Hitch Receiver For a 12k winch I recommend the Bulldog Winch Trailer Winch # BDW10039. Bulldog is a well-known name in the winch community and this specific model comes with a wireless remote that you can use to easily activate the winch from anywhere within a 100' radius. To get this winch mounted to your trailer hitch you'll need the Bulldog Winch Hitch Mounted Winch Mounting Plate # BDW20011 and a reducer. You should have at most a 3" receiver tube opening so I recommend double checking the opening...
view full answer... - Recommended Trailer Hitch Adapter for 3 Inch Hitch Receiver OpeningTo 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 Buyers Products 3" to 2" Receiver Tube Adapter # 337RTA302. This will allow you to use an anti-rattle lock on the 3 inch receiver and then use the anti-rattle...
view full answer... - Are The Rock Tamers 2.5" Compatible With Stow & Go Hitch and Anti Rattle Quiet Hitch?If you have a 3 inch hitch on your 2020 Ford F-350 and you're using the B&W Tow & Stow 3-Ball Mount # BWTS20049B with an adapter sleeve # C45408. You will be able to use the Rock Tamer Mud Flaps # ERT00110. All you need to use these flaps is at least 1 inch from the hitch to the end of the shank of the ball mount. The Tow & Stow has two holes. The front hitch pin hole is 3 inches to the end of the shank and the last hole is 4 inches. So you should have plenty of room to put the Rock Tamers...
view full answer... - Hitch Cover for a 3-Inch Hitch Receiver?We do not have any hitch covers made for 3" hitches. In fact there is only one hitch cover made for 2-1/2" hitch receivers which is the Curt Hitch Cover # C22277. Having a 3" hitch receiver limits your options whenever you want to use it for non-towing purposes. If ever you want to carry around a bike rack or use a non-towing accessory, I recommend having the Curt Hitch Reducer Sleeve # C45408. It's a small adapter that fits inside your hitch so that you can use normal 2" hitch accessories...
view full answer... - Ball Mount Recommendation for 3" Hitch Receiver on Ford F-450The only way to avoid using a reducer sleeve like the Curt # C45408 is to get a ball mount with a 3" shank and for that I recommend checking out the B&W Tow & Stow 3-Ball Mount # BWTS30049B which comes with the 3 common hitch ball sizes (1-7/8", 2", and 2-5/16") and has an adjustable height so you get a max rise of 7" and a max drop of 7-1/2". The idea behind this ball mount is that it will be the last one that you need to buy since it has so much versatility. I also recommend picking...
view full answer... - 3 inch to 2 inch Hitch Adapter that Has 3/4 inch Diameter Hitch Pin HoleHey Tim, what you would want is the Curt hitch reducer part # C45408 which will convert your 3 inch hitch to a 2 inch hitch and has a hitch pin hole diameter of 3/4 inches like you have. The Buyers Products adapter does have the smaller diameter hitch pin hole for the 3 inch hitch side so you'd have to use a smaller hitch pin with it.

This ball mount will use the larger 3/4" hitch pin # 58388 that you mentioned you have, however this ball mount is designed to fit into 3" x 3" trailer hitch receivers. If your receiver opening is smaller, you can use the Curt Hitch Receiver Reducer Sleeves # C45408. This reducer sleeve will allow you to adapt the ball mount to your 2-1/2" or 2" receiver opening.

view full answer... - How to Use Blue Ox Weight Distribution in 3 Inch HitchWhile 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...
view full answer... - Recommended 2-Tang Clevis for 3 Inch Trailer HitchIt sounds like you are looking for a 2-Tang clevis hitch for the 3" receiver on your vehicle. Since there is no 3" option I recommend the Gen-Y 2-Tang Clevis for 2-1/2" Hitch Receivers - 21,000 lbs # 325-GH-069. Along with this clevis hitch you will need the Curt Hitch Receiver Reducer Sleeves - 3" to 2-1/2" or 2" # C45408. This adapter will allow you to use the clevis hitch with your 3" receiver.
view full answer... - 3 Inch to 2 Inch Hitch Receiver AdapterWe 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.

Per the manufacturer it is not designed to be stacked together and it would not work properly. The Curt Hitch Receiver Reducer Sleeves # C45408 is what you will need.

To attach it to your 2019 Ford F-250 you will need a Shank # RP69FR and Reducer Sleeve # C45408 to go from the 3" receiver to the 2" hitch shank.

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)...
view full answer... - Can Hitch Reducer Sleeve Be Used with Weight Distribution Shank Without Loss of CapacityWe 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...

The Yakima BackSwing Swing Away Hitch Extender # Y02483 will allow you to add the etrailer Hitch Mounted Spare Tire Carrier # e98ZR to the receiver on your 2017 Ford F-350. You will likely need a Reducer # C45408 to go from the larger 3" receiver to a 2" receiver. If you are doing hardcore off-roading you may consider using an aftermarket bumper with swing away tire carrier as they are more robust and will sit higher not affecting your ground clearance.
