This adapter increased my revenue by 25% as now I can haul gooseneck trailers. Highly recommend for simi's that do power only with long slide fifth wheel. I really give it a 10 star
by: Tom 10/06/2023
Functionality it's fine. However it was not pri.ed or painted. Also the pin holes were not drilled at a 90 degree with the foot. Foot is angled on the fifth. This is an authentic thing but never ltheless it shows the lack of detail in the manufacture.
Welds are all good and is functional as was meant to be.
by: Korey11/12/2022
Quality control kinda sucks with this one. I'm not happy with the crooked set screws primarily. Also not happy with the crooked load bearing pin holes that so many others mentioned. I bought this combo because it was only $[XX] more than the inner shaft by itself. Tried to get a partial refund or send it back but they want me to pay for shipping, so it's not worth it. I would recommend buying the Bulldog brand, might have better quality design.
by: Loren 03/19/2023
I'm giving this five stars because it's a well-built robust unit for a good price, exactly what was pictured, and arrived before the promised date.
It needed to be better packed, as the heavy piece with sharp edges had torn the box up and the UPS driver was having to take special care to keep it from falling out.
by: Chad03/24/2022
Easy to install. I have my fifth wheel hitch in all summer for my RV so its great to have 1 hitch
by: RB Barnby.07/06/2021
A great way to make your trailer more secure to your tow vehicle. No josseling around from a loose ball connection. Easy hook up, less jacking. Lower your Jack’s to the ground and snug it up. Unlatch and pull out.
by: Rodney07/25/2019
Excellent product easy to install. No more switching between 5th wheel and gooseneck hitch ball.
by: Kris George 09/04/2019
Had to place holes for adjustable neck 90 to length of trailer, made pad catch on a corner when backing in. otherwise I've enjoyed the coupler

See what our Experts say about this etrailer Gooseneck and Fifth Wheel Adapters
- Does Ram Gooseneck to 5th Wheel Adapter KPG5-R30 Require Professional WeldingYes, when it comes to round gooseneck couplers, the industry standard is a 4 inch OD inner tube and 4.5 inch OD outer tube. The Ram Gooseneck to 5th Wheel Trailer Coupler Adapter # KPG5-R30 you referenced includes both the inner and the outer tubes, ideal for people needing to replace a damaged coupler or for someone looking to fabricate a trailer without an existing coupler. It sound like all you actually need is the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter # KPG5-R30IP, which...
view full answer... - Replacement Inner Tube for 30K Gooseneck to 5th Wheel Trailer Coupler AdapterIf the outer tube you have on your trailer now measures to be 4-1/2" diameter then you will not need a new outer tube and you can use the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter part # KPG5-R30IP. However, if the outer tube on your trailer is not 4-1/2" diameter then you will need both, the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter part # KPG5-R30.
view full answer... - Gooseneck to 5th Wheel Adapter for Big Tex 14GNSince you have a 4" round tube you need the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter # KPG5-R30IP. This will replace the inner tube on your Big Tex 14GN. The # KPG5-R30 you were looking at comes with the same inner tube along with the outer tube.
view full answer... - How to Determine Fit of Gooseneck to 5th Wheel Trailer Coupler AdapterThe Ram Gooseneck to 5th Wheel Trailer Coupler Adapter # KPG5-R30 is simply a replacement for the gooseneck coupler currently on your trailer; it will replace both the inner and outer tubes of your current coupler. This adapter has a 4 inch inner tube and 4-1/2 inch outer tube and you will need to have a qualified professional install the brand new coupler.
view full answer... - Solution for Gooseneck Trailer to Connect to Fifth Wheel HitchYou could cut off your gooseneck coupler/tube and have the # KPG5-R30 that you mentioned welded in place of it.
view full answer... - Weight Capacity of Ram Gooseneck to 5th Wheel Trailer Coupler AdapterThe Ram Gooseneck to 5th Wheel Trailer Coupler Adapter # KPG5-R30 that you referenced does not have a stated pin weight capacity. As long as the trailer you tow with it weighs less than 30,000 lbs this would be safe to use.
view full answer... - Plate Thickness of Ram Gooseneck to 5th Wheel Trailer Coupler # KPG5-R30The plate and wall thickness of the Ram Gooseneck to Fifth Wheel adapter part # KPG5-R30 that you referenced is .275 inch.
view full answer... - Towing a Gooseneck Trailer with a 5th Wheel Hitch and Availability of Adapter for 3-3/4 Inner TubeWhile we do not have an adapter that is 3-3/4 inches in diameter I do have a couple of possible solutions for you. First, you could replace both the inner and outer tubes using # KPG5-R30. A certified professional welder would have to perform this installation. This is a viable solution if you will be towing the trailer with a 5th wheel hitch all the time. Second, if your truck has industry standard 5th wheel rails you could use a gooseneck plate instead, such as # 16055.
view full answer... - Availability of Inner Tube Portion of Ram Gooseneck to 5th Wheel Trailer Coupler # KPG5-R30The part # KPG5-R25-IP is just the inner tube of the part # KPG5-R30 that you referenced.
view full answer... - Will Ram Gooseneck to 5th Wheel Trailer Coupler Adapter Fit 1998 SundownerYou will need the safety pin hole to use the # KPG5-R30IP. It should be pretty easy to drill a hole to make this work and then get a replacement pin # GCPN-PIN. Alternatively, you could get the # KPG5-R30 which includes the outer tube with the hole for the safety pin and replace what you have now.
view full answer... - Best Gooseneck Trailer to Fifth Wheel Adapter Solution for Towing with Short Bed TruckYou are definitely on the right track to coming up with the best solution to allow you to tow your fifth wheel trailer and gooseneck trailer. Since you have a short bed truck it is important that you have turning clearance which converting the gooseneck to a king pin does allow you to still use the slider hitch and have the clearance you need. Since you have the standard 4 inch tube on your trailer the king pin adapter part # KPG5-R30IP is the way to go. This will fit in place of what...
view full answer... - Dimensions of the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter The overall length of the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter - Round - 30K item # KPG5-R30IP is 29". It is 14" from the top of the tube to the first adjustment hole. I have attached a diagram detailing these measurements.

- Will Ram Gooseneck to Fifth Wheel Adapter Use Same Connection as Tractor TrailerTractor trailers do use fifth wheel hitches for connection so yes, the Ram Gooseneck to 5th Wheel adapter part # KPG5-R30IP would provide the connection needed for a gooseneck trailer as it will convert it to a fifth wheel king pin.
view full answer... - Dimensions of the Pin Holes and the Pin Hole Diameter on the Ram Gooseneck to 5th Wheel CouplerThe Ram Gooseneck to 5th Wheel Trailer Coupler Adapter, part # KPG5-R30IP, fits most standard round gooseneck outer tubes. The Pin Hole Diameter is 7/8 inches and the Adjustment Holes, center to center, are 2-11/16 inches apart, giving it a Range of 8 inches for Vertical Adjustment. The Tube Diameter is 4 inches and the Plate Dimensions are 9-7/8 inches long and 9-7/8 inches wide.
view full answer... - Diameter of the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter # KPG5-R30IPYes, the outer diameter of the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter # KPG5-R30IP is 4 inch.
view full answer... - Base Plate Size And Capacity Differences On The Ram Gooseneck To 5th Wheel Coupler AdapterI contacted the manufacturer on your behalf regarding your question. Per Ram, the plate is the same 10"x10" size on the # KPG5-R25-IP and the # KPG5-R30IP. Our review video also had it measured the same. The capacity difference increase for the 30k comes by way of the welded belly band around the bottom of the outer tube. The 30k capacity also comes from the .275" inner tube wall thickness vs the .24" inner tube wall thickness on the 25K. Included are video resources for more information...
view full answer... - Recommended Adapters to Tow Gooseneck Trailer With 5th Wheel HitchSo you're wanting a king pin adapter that would take the place of your gooseneck coupler, is that correct? If that's the case, the best way to do that wouldn't be to add a pin box. You'd want to use a king pin adapter instead. Attempting to use an actual pin box would require lots of fabrication and engineering work to ensure the assembly would have the proper weight rating, as well as achieving the proper height so the trailer is towed level. The coupler adapter you need will depend...
view full answer... - 5th Wheel Slider Hitch Adapter For Gooseneck Trailer You will need to lock out the sliding function on your Pull Right 5th wheel hitch to use the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter item # KPG5-R30IP. If you can not lock out your slider than I recommend the Curt Spyder Gooseneck Trailer Hitch for Fifth Wheel Rails Item # 16085. This adapter mounts to industry standard 5th wheel rails, has a 2-5/16" trailer ball, comes with safety chain attachments, and also includes pins and clips for rail attachment. I have attached a picture...

- Can Lube Plate Be Used with Ram Gooseneck Coupler Adapter # KPG5-R30IPYou can absolutely use a 10" lube plate such as the Curt # 16721 with the Ram Gooseneck Coupler Adapter # KPG5-R30IP to keep the hitch head lubricated and scratch free. You may just want to take a look at the manual for your particular 5th wheel hitch, as some will note a maximum thickness on a lube plate like this. If you can tell me what model hitch you have I can also check this for you.
view full answer... - How Does the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter WorkI am not sure I understand what you are asking. The Ram Gooseneck to 5th Wheel Trailer Coupler Adapter part # KPG5-R30 installs on the trailer, not the tow vehicle. It is designed to replace the gooseneck coupler on the trailer and allow for connection to a 5th wheel hitch as opposed to connection with a gooseneck hitch ball. The old coupler will need to be cut off and the new outer tube will need to be welded on the trailer by a professional welder. The inner tube will then slide in the...
view full answer... - How to Tow 5th Wheel Trailer With Gooseneck Trailer HitchWhile we do have a way for you to tow your 5th wheel trailer with your truck that has a gooseneck trailer hitch, the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter # KPG5-R30 only fits gooseneck trailers so it wouldn't work for you. The best way to tow a 5th wheel trailer with the gooseneck ball in your truck is with the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter # DM8550045. This is a 5th wheel hitch that attaches directly to your truck's gooseneck ball, allowing you...

- Solution to Convert Gooseneck Trailer Coupler to Fifth Wheel King PinWe don't have an inner tube replacement king pin adapter that you can replace yours with but you could use the Ram Gooseneck to 5th Wheel Adapter part # KPG5-R30 which would require you to cut off the outer tube you have now and weld this in place if it. Regardless of if you could find an inner tube setup that would fit it wouldn't work since the king pins sit up a lot higher than gooseneck couplers. This is due to fifth wheel hitches being typically about 12 inches taller than gooseneck...

As long as the overall trailer capacity figure is not exceed of either you'd be safe. The part # KPG5-R30IP has a 30k capacity and the # KPG5-Q25-IP is rated for a 25k trailer.
