Video Transcript for Curt Gooseneck and Fifth Wheel Adapters 16310 Review

Speaker 1: Today I'm going to take a look at the Curt X5 fifth wheel base rails adapter for the B&W turnover bulb gooseneck trailer hitches and this has a 20,000 pound weight capacity. Now this adapter is designed to mount in to your gooseneck trailer hitch to supply these above bed base rails, which are necessary for installing a fifth wheel hitch to your vehicle.This is designed to work with the B&W standard center turnover ball gooseneck hitches, and the rails are designed to work with the above bed fifth wheel hitches by Curt, B&W, Demco, Draw-Tite, Hidden Hitch, Husky, Reese and Valley. It is a very fast, easy installation. This adapter, if you look here, I'm going to turn it around. If you see in the very center is a square post. You just drop that square post end of the adapter into the square gooseneck ball hole, and then lock it into place, and then that will give you the rails right here in your truck bed.On the underside of the rails, they do have rubber pads, which will help prevent these rails from rattling and sliding in your truck bed.

This is made of a sturdy steel construction. It has a nice black carbide powder coat finish to it, for superior durability and rust resistance. This part is made in the USA.Specs on this again, the gross towing weight capacity is 20,000 pounds, vertical load limit is 4,000 pounds. But that should do it for the review on the Curt X5 fifth wheel base rail adapters for B&W turnover ball gooseneck trailer hitches.

I recently purchased a used '08 Ford F-350 with a B&S turnover gooseneck hitch. I wanted to use a Reese 16k hitch that I already own and put it in this truck without doing the typical bed rails to attach the fifth wheel hitch. I contacted Etrailer and they quickly identified the Curt X5 adapter to solve my issue. Ordered new adapter and in 3 days I had the unit and everything fit perfectly. This is the second time I have dealt with Etrailer in the last 6 months and I continue to be impressed with all aspects of this company. I'm glad I found Etrailer 6 months ago when I was looking for trailer hub and brake parts. I knew just who to turn to with my latest needs. Thanks Etrailer! 208661

Great. Works well to allow me to go from goose neck to fifth and back again with ease. Very satisfied!

Ordered Curt X5 Fifth Wheel Adapter for my B&W Square Shank Turnover Ball Hitch and received it in two days. Had it installed in my trucks in a matter of minutes. Just pulled out the ball and inserted the adapter, no holes to drill in my truck bed and simply unpin it and remove it to have full use of my bed. Love it! 192930


Comments

It is great! Just got back from a 4800 mile trip and unhooked my fifth wheel and pulled the pin and removed everything from my truck bed. The only way to go!

Received the Curt X5 B&W turnover ball adapter yesterday. Would have been easier to drop in with two people but I was able to do it myself. Dropped right in, and in less then 15 seconds it was dropped and locked. Saved me lots of install time on 5th wheel rails. Set my RBW lil' rocker hitch on and pulled my 10,000 lbs 32' 5th wheel across town without issue. I feel that this is probably the strongest way to go when running a 5th wheel to turnover ball adapter, and its only about $*** which is a fraction of the cost for those other weird complex adapters that side load or flex. Customer feedback was great with optimal response time on my questions. 266615

Nothing fancy, strictly utilitarian and simple. Built like a bomb shelter and shows no signs of wear. I pull a Keystone Laredo 298BH almost bi-monthly and this gives me the flexibility I need to switch hitch styles between trailers. If you need a completely flat bed for hauling then you still have it versus bolted on bed rails. Much safer than a 5er extension and doesn't void the warranty on your travel trailer if there is a failure. I shimmed mine off of the truck bed to take out the slop with 2 sections of round baler belting from a tractor supply store attached via industrial adhesive and it works beautifully. It weighs a lot so swap outs are a bit of a chore but i wouldn't want it to be built any lighter. Bravo on a great product 357271

After reading numerous favorable reviews on the goosseneck to 5th wheel adapter #16310 I decided to purchase one from etrailer.com. My entire experience has been truly outstanding. I ordered the adapter on Sunday night and Monday morning I received a phone call confirming my order and address. The order shipped on that same day and arrived on Thursday. I installed the adapter in my truck within minutes and installed my HUSKY slider hitch within minutes with absolutely no problems. I picked up my new 5th wheel and the adapter and hitch worked perfectly. I highly recommend etrailer.com and the Curt X5 Fith Wheel Adapter for B and W Square Shank Turner Ball Hitches-16310. 170741

I just wanted to say the people at etrailer are some of the best people to do business with. Me being someone who always seems to get broken or flawed items when i order online can with all honesty say i feel they went out of their way to make sure my adapter arrived in time for my trip and in excellent working order! I have looked thru their site and seen all the stuff they carry and if they have or can get it i will do business with nobody else. If you want a company that does business they way it's supposed to be done than you can't go wrong with these guys! Thank you so much and it's all my pleasure to give a 10star review.... 192401

Excellent product, well made and fits as it should on both sides. A device like this, to be worth making and selling, has to have certain assumptions as to fit and function. Curt has done a great job of giving the customer flexibility in fitting up. In my case the (turnover ball) pin went part way in and stuck tight. I thought that removing the rubber shims on the underside of the adapter would be too much downward movement, so, with 5th wheel hitch installed, I found some washboard road to drive on. Problem solved; pin works perfectly. By the way, I call this thing a "spider". After all it has 8 legs. 426799

This is just what I was looking for, already had Curt R5 slider hitch, put B&W hitch on new truck. Tried a gooseneck adapter, but too much flex. Went back to 5th wheel hitch. This adapter is built heavy, weighs over 100lbs by itself. I pull a 14,000lb toy hauler, with a F250 shortbed, needed the slider. I feel much safer with this product. Ordered from e.trailer, shipping was right on, only 3 days. 134542

I just purchased a used pickup that had a B&W square shank ball set up in it. I really was not looking forward to the headache of installing a rail kit, what with the drilling etc. that is required. I kept searching until I found this product. For a comparison: frame rail install with all drilling that's required, several hours; installing this, 30 seconds. It's definitely the way to go if you already have a gooseneck ball set up in your truck. I was also very impressed with how quickly the item arrived. I was expecting a week or so, instead it arrived in three days. I am very happy all the way around. 158746

Great product! Ive pulled a 42' to Hell and back not one problem. It is heavy, but it's very solid. My fifth wheel hitch fit straight in. Way cheaper than having to put rails in if you have a factory ball hitch in the bed. Its It's also nice that it's removable so you can haul furniture, or things that can't sit crooked ect. Great product, should last forever. Definitely would recommend 261579

Have a truck with a goose neck hitch but needed an adapter to haul a 5th wheel trailer. This hitch is very easy to use, fits well in my bed (truck bed is very banged up and uneven from years of demolition/ remodel work and fire wood hauling), and is quick to place and remove. The adapter lays flush enough in the truck bed that it wouldn't affect most loads or cargo (i.e. Lumber, mulch/bark, fire wood, etc.) My 5th wheel hitch (Reese) fits perfectly with the hitch. I am incredibly pleased with all aspects of this product. Worth the price for the ease of use. 262334

The X-5 is a heavy built, nicely finished adapter. It literally took me longer to open the box than to install it. I slipped it into the opening myself. I owned a Pro 15k which slipped right into the rails. I had assumed when I purchased this product (as it was advertised to fit a B&W turnover) that there was a built in offset to counter the typical 6" install towards the cab. After measuring my trailer it's appearant that a slider is now needed. It would be ausome if there was an option for an offset especially for the price. 336435

I cannot not say enough about trailer. Always have had my back with price,knowledge, and the best customer service. I have the Curt X5 Adapter and love it. I have it coupled to the Q24 her hitch My tow vehicle is a 2013 GMC 3500 Dually 4WD and tow a 40' 18k 2012 Keystone Raptor 372122

Heavy duty. But it does not drop into B & W under bed hitch far enough for the capture pin to engage the hole in the Curt adapter. I am not going to modify my spray in bed liner to solve this problem. Curt should make the hitch work without the need to modify a spray in liner. ( A larger hole in the Curt drop in shaft?) Maybe when I am able to drop the trailer onto the hitch it will engage the B & W under bed pin due to the extra weight. At this point I'm not satisfied . 345043

I recently purchased a 2015 Denali HD to pull our Rockwood 5th wheel. This truck had the B & W goose neck already installed. Instead of removing the hitch from the previous truck, I decided to try the B & W with the Curt X5 5th Wheel adapter. After reading the reviews, I was anxious to see if it fit as some said it did and others not. I ordered it on Wednesday and received it the following Monday. It was so easy to install and fit perfectly. Thanks etrailer. 424867

What a deal, much lower price then anybody else, extremely fast shipping! Just drop it in, set the hitch, good to go. When done, take out the hitch, take out the adapter and have a perfectly smooth bed for whatever. Appears to be heavily built, very solid and how much simpler can you get, drop it in the gooseneck hole, throw the lock lever and you're ready! Like everything else I've order from etrailer, top notch stuff at great prices! 420637

Managed to get my hands on a curt E16 5th wheel hitch and couldn’t be happier with the combination. The drop in weighs 100lbs and is honestly really easy to install. The hardest part is getting it from where it’s stored to the back of the truck. 460578



- 16310

by:


Excellent product, good build quality, it didn't work for me as a drop in and use it but etrailer was willing to make it right. My fifth wheel hitch bolted right in with no issues. Excellent how all pieces can be removed leaving a flat bed surface. Do not expect this to fit in 2017 F250 with B&W turnover ball (bwgnrk1117) as it will not lock in place since the ridges in the truck bed are different height than previous year trucks. 389696

Received product 4 days after ordering with free shipping. Seems really well made. No noises or clunks when towing. It dropped right in to my b&w gooseneck and my Reese 5th wheel dropped directly into it. Good product. 515924

Excellent product that solved my issue of needing both a gooseneck & fifth wheel hitch in the same truck. Drops right in & fits perfect even with a spray in bedliner. Just towed our 20,000 lb toy hauler with it this past weekend- it performed flawlessly. It actually felt no different than our other truck with the fifth wheel rails bolted in, plus it can be removed & you can be back to pulling a gooseneck in minutes. 494852

I ordered the curt adapter for my already installed B&W turnover ball and it works just as advertised. I had a spray in bedliner which didn't cause any issues. When I contacted etrailer Chris was very helpful and knowledgeable. Any question she wasn't sure about was directed to a technician who was able to answer. The item was packed very well and arrived in near perfect condition. Overall excellent experience. 351504

5th wheel adapter plate fits perfect in ball socket. The hitch which I'am mounting to the adapter has a solid bottom, it will not allow the hitch to mount to the rails. I was wondering if you sold a 2" spacer kit # 46250 for a ts3 Trailer saver hitch? If so how much is it. Rubber Pads were put on backwards so the stuck to the box instead of hitch. can I get 4 pads? Thanks Richard C.Holt 230749



- 16310

by:


I was so happy to discover this adapter. I had to have a gooseneck hitch and wanted it to be hidden. I was dreading the fifth wheel rails sticking up in the bed again (bed replacement). This does the trick. Only reason for 4 starts is that it is a bit tight with no bedliner. Not even a spray in. But, I guess the maker has to build to a certain spec and not everyone would have a bedliner... 438660

by:


Etrailer did a great job of shipping very very fast received in just three days. The X5 it's built very sturdy and it is very heavy it seems to be very strong. The only issue that could be with this product is when you use it with a B&W hitch it seems to set it a little deeper in the bed maybe about 6 inches behind Center axle. If you don't have a slider hitch this could be a problem 245646



- 16310

by:


Great product and easy to install. etrailer staff was great. Shipping was fast. One note: if your goose neck pin doesn't fully engage due to a spray in bedliner, connect up to your trailer and the weight of the trailer should allow the pin to fully engage. After my first trip the adapter settled enough and the pin engages easily without the trailer weight. 230906



- 16310

by:


Received product very quickly within 4 days with the free shipping option. The adapter dropped right in. The only issue I had is two of the small rubber pads came off the bottom of the adapter and we're stuck to the cardboard so in useable. I put the 5th wheel hitch on the rails and everything lined up except the two pins on the cab side will have to be hammered in. 209303



- 16310

by:


I think this is great very handy and easy to operate just drop it in and go. The one thing I found out when I first used mine was there is a only one way to put it in and pin it properly. I had to take it out and turn it 180 degrees and drop it in, then the pin went in all the way. It's a very tight fit and that's important to me. Great product! 475630

I shopped around looking for a better price but etrailer.com beat them all. Top it off with free shipping and I couldn't pass up the deal any longer. The item was delivered promptly for free at the lowest price on the net. I'm very happy with my etrailer.com purchase and I will shop them again if I need anything else for my truck. 242203



- 16310

by:


Shank was too long. It bottomed out in the gooseneck hole an inch and a half at least before the rails touched the linex. Some modification was needed to make it work. Can't just drop it in and go. Glad I wasn't going camping the week it was delivered! Looks well built and the idea is good. Just needs to fit as advertised! 200398



- 16310

by:


Great product, fits perfectly and performs well. I have the B&W turn over ball hitch and considered the B&W 3500 5th wheel. I bought this instead, about $500 less expensive and used my existing 5th wheel hitch. No issues and saved the money. Caution lifting this piece, it is over 100lbs, highly recommend using two people. 196913

Have not towed with it yet, but was very excited when I saw the quality of the adapter. Really pulled through for me on the two day shipping guaranteed. I just found out my Husky 5th wheel sliding hitch does not fit. Ouch! Can't knock the set up! I think, I will just get a different 5th wheel hitch. Thanks etrailer! 192704

This is so much better than having the rails permanently in my truck. The installation went well. Having to cut the heat shield is one of those moments on a brand new truck but it needs to be done. I recommend getting a plug for the turnover ball. Winter salt will not be kind to the ball in the turned down position. 290262

This rail system is great fits in awesome as long as you cut ur bed liner so it can sit on the bed flat it's a awesome product I would recommend this to anyone the has a B&W turn over hitch it would of been nice not have to cut the bed liner to make it fit wish I would of locked in with the plastic bed liner intacked 347495

Yeah it fit it into my B&W gooseneck hitch. I just had to grind down some of the sprayed in bedliner. and then the pen went in and my Reese's fifth wheel attached right to it. seems to be working good be taking a trip in June then I'll find out how good it really is. 368557

The X5 just arrived. I was very surprised that Curt spared nothing on building this. Talk about solid. Took 3 of us to set it in the back of the truck. I'm gonna love it. I can have my sturdy hitch and when not hauling, my clean truck bed. 230512

Great product, had it for about a year. I leave it in the truck all the time. It's very heavy. No complaints. I think if I used the turnover ball for gooseneck I would install rails. My B&W is a bit rusty and hard to switch out. 344745

  • I spoke with my contact at Valley and the Valley Gooseneck-to-Fifth-Wheel Adapter Plate, # V70881, will not work with the Curt slider rails. Instead, I would recommend using the Curt X5 Adapter Plate, # 16310. This adapter plate will work with your Curt fifth wheel hitch and slider rails and has a maximum weight capacity of 20,000 lbs. This adapter plate will work with the B and W square shank turnover ball hitch and retails at a lower price than the Valley adapter plate # V70881.

  • Installing a 5th Wheel Hitch in a 2004 Ford F-250 With a B and W Gooseneck Hitch
  • I have a few solutions for you, however, a gooseneck hitch and a fifth wheel hitch will not typically fit together on a truck. The frame brackets of the gooseneck hitch or fifth wheel hitch will interfere with the frame brackets from the other hitch. This would be the case on your truck if you tried to install the Reese Universal Fifth Wheel Install Kit, # RP30035, that you referenced. The frame brackets for your B and W gooseneck hitch will prevent the frame brackets from fifth wheel base...

  • If you want to equip a 2016 Chevrolet Silverado 2500 6-1/2-foot-bed pickup for both gooseneck and 5th wheel towing then I suggest you consider the B&W Turnoverball Underbed Gooseneck/5th Wheel Installation kit # BWGNRK1016. This kit by itself serves as a complete gooseneck hitch system. When you need the bed empty for cargo the entire hitch can be removed for full access. When you want to do 5th wheel towing all you need to do is insert the matching Companion 5th wheel hitch, either...

  • Does Demco 5th Wheel to Gooseneck Adapter Fit Better than the Curt X5 Adapter
  • The Demco adapter # DM6140 does have that draw down bolt similar to the one found on the Companion to make it good and tight. If your truck happens to be a certain year Ram, Toyota, or Ford truck then the exact problem you are describing is a known issue. There are actually several caveats surrounding the X5 adapter # 16310: Will not work with any 2013 - 2016 Dodge Ram 3500 or 2014 - 2016 Dodge Ram 2500 trucks that have a B&W Turnoverball gooseneck hitch installed. Will not work...

  • Fifth Wheel Adapter for a Draw Tite Hide-A-Goose Gooseneck Hitch
  • I have a solution that could work well for you, but there isn't an adapter exactly like the # 16310 that would fit a Draw Tite turn over Hide-a-Goose. Instead I would recommend the Hi-Rise Gooseneck-to-5th-Wheel Trailer Hitch Adapter # 9480. This will fit in your gooseneck hitch easily and will provide you with a fifth wheel hitch. I attached an install video for you to check out as well.

  • How is the Height Adjustment Measured on the Curt Q20 5th Wheel Trailer Hitch
  • When measuring the height of a 5th wheel hitch it would be from the top of the truck bed corrugations to the top of the head. The Q20, # C16130, is height adjustable from 13 to 17 inches. Since the X5, # 16310, sets in a gooseneck ball hole but the rails would be no higher than regular rails, it does not add height. To get the proper height setting you would need to know the distance from the top of the bed side rails to the bottom of the trailer overhang. You need 5 or 6 inches of space...

  • Installing Fifth Wheel Hardware Over Existing Gooseneck Plate on a 1997 Dodge Ram 2500 8 foot bed
  • According to my technical contact at Reese it is not recommended to have both a gooseneck and fifth wheel hitch installed at the same time and to have both useable. The reason for this is exactly as you have indicated that the mounting hardware that secures both of the hitches to the truck uses the exact location on the truck frame. If you were to drill through the existing hardware in order to mount the fifth wheel hitch it could compromise the integrity of the gooseneck hitch. These hitches...

  • Fifth Wheel Rail Adapter Recommendation for a B and W Turnover Ball Gooseneck Hitch
  • Since you have a B and W square shank turnover ball gooseneck hitch in your truck all you would need to convert this hitch to standard fifth wheel rails would be the Curt X5 Adapter part # 16310. This will fit right into your hitch and would work great. Check out the review video I attached for more info.

  • Dimensions of the Mounting Holes on the Curt X5 Gooseneck-to-5th-Wheel Adapter Plate
  • The Curt X5 Gooseneck-to-5th-Wheel Adapter Plate, part # 16310, has three sets of mounting slots for fifth wheel hitches. The slots are the same dimensions as the mounting slots on the industry standard base rails. I have attached a diagram that shows their dimensions. The Curt adapter plate works with Reese 15K, 16K, and 18K fifth wheel hitch. I spoke with my contact at Reese and he said the 14K should also work, because the Reese 14K hitch became the Reese 15K hitch. I am including...

  • Can the Curt X5 Adapter be Used with a Pullrite Superglide 5th Wheel Trailer Hitch
  • The Curt X5 Fifth Wheel Adapter for B and W Square Shank Turnover Ball Hitches, # 16310, is designed for use with B and W square shank turnover ball hitches. We spoke with Curt and they stated the Pullrite 5th wheel hitch is not compatible with the X5. The reason is because the rails that are required for use with the Pullrite 18k Hitch are of a completely design than what comes on this # 16310. The rails on the pull rite are more of a male connector style while the hitch is female....

  • What 5th Wheel Hitches Will Fit My B&W Turnover-Ball Gooseneck Hitch
  • Yes, the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter part # RP94622-61301 will work with any brand of gooseneck hitch as long as they have a 2-5/16" hitch ball like the B&W Turnoverball Underbed Gooseneck Trailer Hitch part # BWGNRK1057. Unfortunately, we do not carry the Andersen Ultimate 5th Wheel Hitch at this time. However, you can use the Curt X5 5th Wheel Base Rails Adapter for B&W Turnoverball Gooseneck Trailer Hitches part # 16310 that will allow you to use...

  • Gooseneck to Fifth Wheel Hitch Adapters Compatible with Round Shank Curt Receivers
  • We have a solution that will give you the ability to use a fifth wheel adapter with the Curt gooseneck hitch you have in your truck, but there is nothing that will allow your B&W Companion hitch to fit into the round ball hole on your gooseneck hitch. We do carry the Curt X-5 Hitch Adapter Plate, part # C16210, that is designed to work with your Curt hitch. This adapter comes with the round shank needed for the gooseneck hitch you have installed in your vehicle. Once this adapter I installed,...

  • Compatibility of Curt X5 Adapter # 16310 with Reese 16K Sliding Fifth Wheel Hitch
  • The bed rails used on the Curt X5 Fifth Wheel Adapter are indeed compatible with Reese standard and sliding hitches. This particular adapter is only compatible with B&W Turnover Ball Gooseneck Hitches using a square shank. I have linked you to the install details for the adapter, as well as an FAQ article on Fifth Wheel to Gooseneck adapters.

  • 5th Wheel Trailer Hitch Adapter for an Under Bed Mounted Gooseneck Trailer Hitch on a Ford F-250
  • I did some research on that part number as it might apply to a gooseneck hitch. One website I came across listed 62104 as a Draw-Tite Hide-A-Goose under bed gooseneck hitch. If it is a Draw-Tite Hide-A-Goose, then the Curt X-5, # 16310, will not fit. If you want to add a 5th wheel trailer hitch, you can use the Hi-Rise Gooseneck to Fifth Wheel Trailer Hitch, # 9480. This 5th wheel trailer hitch fits B and W Turnover Balls, Hide-A-Goose from Draw-Tite, Hidden Hitch, or Reese, and Bulldog...

  • What are the Differences Between Hitches 16310 and V70881
  • According to my contact at Curt, the X5 does not require a support kit because it has the rails and attachments needed as part of the assembly. It sits flush with the bed so it does not need a separate subkit because the subkit is already installed. Also the rails on the Curt X5 Fifth Wheel Adapter for B&W Square Shank Turnover Ball Hitches, # 16310, have more openings for more 5th wheel installation options than the Valley B&W Gooseneck to Fifth Wheel Hitch Adapter Plate, # V70881.

  • Gooseneck to 5th Wheel or 5th Wheel to Gooseneck Trailer Hitch Options for a Lifted Truck
  • With a lifted truck, it will be a tight fit, but I may have a couple of options for you. First, take a look at the Hi-Rise Gooseneck-to-5th-Wheel Trailer Hitch Adapter, # 9480. This will fit a B and W Turnover style gooseneck hitch. The hitch height is adjustable from 14-1/4 inches to 18 inches. You will need to measure from the bottom of the pin box (not the king pin) to the top of the bed to determine if this height is too much or not enough. Another option is a 5th wheel to gooseneck...

  • Will Curt X5 Adapter Plates Allow a Reese Fifth Wheel to Be used on a B&W Turnover Gooseneck
  • Yes, the Curt X5 Fifth Wheel Adapter for B&W Square Shank Turnover, will allow you to use your Reese 15K Fifth Wheel hitch. The Curt Adapter works with Curt 16K and 20K hitches as well as Reese Fifth Wheels up to 20k among other manufacturers.

  • Curt X5 used with Highjacker Sliding Fifth Wheel
  • The Curt X5 Fifth Wheel Adapter # 163140 that you referenced is designed to work with any fifth wheel hitch that can install into standard fifth wheel installation rails, I could not find any information on whether or not the Hijacker hitches utilize the standard fifth wheel rails so I cannot say for certain. I spoke to my contact at Curt and he did not have any information on the Hijacker hitches so he could not say for certain if the X5 would work with your hitch. I attached a...

  • 5th Wheel Trailer Hitch Mounting Slot Dimensions for Valley Gooseneck-to-5th-Wheel Adapter Plate
  • The slots on the Valley Gooseneck-to-5th-Wheel Adapter Plate, # V70881, measure approximately 20-1/2 inches apart on center from side to side. Front to back on center they are approximately 22 inches apart. This adapter plate has been discontinued since Valley went out of business, but I recommend looking at the Curt X5 Adapter Plate, # 16310. This adapter also works with the B&W gooseneck hitches and it will accommodate a Draw-Tite, Hidden Hitch or Reese hitch rated for 15K, 16K, or 18K,...

  • Will Trailer Side to Side Movement Raise the Rails on the CURT X5 Adapter and Damage the Truck Bed
  • It is unlikely that the movement of the 5th wheel trailer would be able to move the rails to such a degree as to damage the truck bed. The rails on the CURT X5 Fifth Wheel Adapter, # 16310, are not like regular rails. They have extra steel on the bottoms to create more surface area contact. This spreads the weight and pressure to a larger area. Combine that with the downward weight of the hitch and trailer and the fact that the adapter is pinned, and it is very improbable there will...

  • Will the Curt X5 Fit a Pro Series 5th Wheel Trailer Hitch and Fit Over a Bed Mat
  • Curt states that bed mats can affect the fit of the X5 # 16310. Basically if the Curt X5 can be pinned in like normal then it can be used with a bed mat. If it cannot then you would need to trim the mat in the shape of the X5 in order to get it to pin in and lock properly. Because every truck and bed mat combination is going to be slightly different there is no set list of vehicles and mat combinations available to determine if it will fit or not. The pin hole center for the X5 is approximately...

  • Recommended B&W Turnoverball Fifth Wheel And Installation Kit For 2017 Ford F-250 Short Bed
  • Since you have a B&W Turnoverball Underbed Gooseneck Trailer Hitch in the bed of your 2005 GMC truck, I recommend foregoing the puck system in the 2017 F-250. I would instead install part # BWGNRK1117 in the F-250 if it is a 4-wheel drive. for a 2-wheel drive you would need part # BWGNRK1116. I then recommend using the B&W Companion Slider Gooseneck-to-5th-Wheel Trailer Hitch Adapter, part # BWRVK3400. The Companion is one of the premier fifth wheel hitches we offer and with the slider...

  • Is the CURT X5 5th Wheel Adapter Compatible with a Pullrite Superglide 5th Wheel Trailer Hitch
  • I spoke with my contact at CURT about the X5, # 16310. He could not confirm a fit for the Pullrite Superglide 5th wheel hitch as they have not been tested together. However, he did provide me with the mounting tab spacing for you to compare to your hitch to determine fit. The mounting slots for the tabs on the 5th wheel measure 22 inches front to back on center. From left to right on each rail, the slots furthest out are 29 inches apart on center. The next set in are 21-1/2 inches...
