Product fit perfectly with no problems. The 5th wheel assembly I already had fit on the adapter plate. Saved me from having to buy a new and expensive 5th wheel hitch. Great product.

This adaptor is the reason I went with the under bed Kurt gooseneck. You can get the whole package at a reasonable price and trust that nothing is going to fail. Well made product. It's just light enough to manhandle, yet just heavy enough to trust.

Is an ok at best product in my opinion. I placed a brand new Reece 20,000 5th wheel hitch in the Curst Base Rail adapter to find that the holes for the pins did not line up the best. 3 of the 4 were close enough for the pins to go into, the last hole (front hole on right side) had to have approximately a 32nd and close to a 1/16th of an inch of metal removed for the pin to line up correctly and go through the hole. I have since purchased a different truck and installed a B & W gooseneck hitch and purchased a B & W rail system. The new B & W system is flawless and works great. I have attempted to sell the Curt X5 base rail adapter online with no success, currently it is simply taking up space in the corner of my shop.

Received my order in 3 business days, with free shipping and It was an exact fit! Plan on buying here from here on out!!

Heavy and doesn't fit flat on my truck bed, had to add some heavy duro rubber shims between this and the bed floor. I paired this with the C611-624 gooseneck hitch.

Everything arrived in perfect condition. With a little trim of the bed liner the adapter fit perfectly as described. My Curt A-16 hitch looks great paired up with the gooseneck adapter. Ready to hit the road!

Works great. The fifth wheel adapter has been used to tow my 19,000 gvw 5th wheel trailer from Wisconsin to Texas back and forth for 2 years.

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


I love this hitch adapter. I mostly pull gooseneck trailer, but occasionally I need to pull a fifth wheel. Easy to get in and I haven't had any problems getting it back out when I was done with it.

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


Fits perfectly into curt goose neck hitch. My reese 5th wheel hitch fits on the rails perfect. I haul dirt bikes in my truck so being able to take the rails out is perfect..... nothing in the way of loading or unloading


Comments
Will the Curt gooseneck to 5th wheel rails adapter work with a Pro Series Slider 5th wheel? That is, will the slots match up?
-- comment by: Mike - 05/11/2014

Yes. The tab slot spacing is pretty universal amongst most manufacturers including Curt and Pro Series. Your Pro Series slider will drop right in to the the Curt X-5 adapter.

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


The rails are well made. But on the heavy side I’m reluctant to pull it out. I would like them to stay put also, they tend to move around some with the B&W hitch.


Comments
As long as you do not have a B&W Patriot or a thick bed liner this should be compatible. I would just be sure that every fastener is tightened down and you should be good to go.

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


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

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


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.

Fit like a glove. Dropped right in and I installed the 5th wheel hitch in no time. Heavy and well built.
