These longer U bolts allowed us to attach the trailer guides that our new BEAR trailer did not come with. The trailer guides are a game changer when putting our Bennington Tri-toon on the trailer, especially in the wind with the bimini tops up.

@Jeffrey Thanks for sharing!

The Post Guide-Ons arrived quickly and have been installed.
They have not been water tested yet, but look like they will do the trick. Loading the boat on the trailer has been challenging when you can’t tell where you are side to side.
A couple things to consider: The width of the boat relative to the frame of the trailer make the bottom tubes of the guides just barely long enough. I believe it will work, but another inch of tube would be good for my setup. When installing, if you have a deep socket, you won’t have to switch to an open wrench. Other than that, I am very happy with these!



by:

I have a welded aluminum boat with extended transom. I really needed some Guide-Ons mounted at the rear of the trailer to ensure that the extended transom centered up on the trailer bunks, as cross currents at the haul out would often skew the boat to one side, and I would need to back down in to the water and re-center. Frustrating when people are waiting in line!!
I got the CE Smith Guide-Ons, but was dismayed when I opened the box and found that the included U-Bolts were not long enough for my 5 inch EZ Loader trailer frame. A quick search of etrailer and I found the solution with the Extra Long Bolt Kit.
Worked perfectly. Now my boat stays centered when I haul out on the first try.



by:

I have now had 5 orders with etrailer and i can say that anything i need in the future will be made with them. In stock , fast delivery ,quality products



by:

U bolts were perfect for the frame on our trailer. Appreciate the aircraft nuts to keep everything secure.



by:

Stacie was fantastic in helping me order the right product for my boat trailer. It was delivered when promised. I have not yet had the chance to install the 60” guide-ons on my trailer but expect no problems . This is at least the 3rd time
I have ordered from etrailer. They are great to deal with. Customer service is outstanding



by:

Great price. Excellent side bunks for my boat trailer. Extra long U bolts made everything perfect. Will use e trailer again!!



by:

I updated my trailer by adding a set of guide-ons and its been a real plus especially on breezy days or loading /unloading by myself.



by:

Excellent product. Just as advertised. Easy to install solo and made of solid materials. Haven’t used to pull boat out yet, but can’t imagine it won’t guide me in great. I used the extra long U-bolt kit because of my trailer being 6 inches. Not sure why they wouldn’t just include them from the beginning as they are only a 1/2 “ longer, but that’s the way it goes. Very satisfied



by:

Unfortunately, the guideons i purchased did not fair well in the sun, and bent from the heat, to a point they were unusable. One side, not in the sun was usable, the other bent so far from sides of boat it was unusable in about 3 months time and 3 trips to the water. Bought a different set from a different vendor.



by:

Once i received my 6" ubolts i was able to install my guides on my trailer.
parts arrived on times very satisfied with the service i will buy from e-trailer again



by:

Arrived as promissed. Appears to be qulity material.The only site that offered larger u-bolts which I needed. Instructions could be better for an open bow boat but I may need to experiment. Overall pleased so far.

I am sorry to hear that you are missing your items. Let me get you over to our customer service department for them to look into this for you.



by:

These bolts are perfect for our trailer.



by:

Received my order. Only to find out it had missing washers.Also spent more money buying your extra long bolt kit only to find out that I needed to purchase more hardware [video] company doesn’t include to actually finish project. Bought the finishing hardware from someone else. I will not be buying from e trailer in future.



by:

Product sturdier than i imagined. Installed so easily. had to get the longer u bolts for my frame. 60" was perfect for my 21' boat. Very happy with delivery and tracking ability. I am a new and satisfied customer.



by:

I would have given 5 stars if you used any other delivery service other than USPS. My stuff came three days late for me. Pulled my boat out the day o was told it would be delivered. Cost me time and money.



by:

These worked for standard 5" Trailer r ails.



by:

The bunks worked great. Boat went on the trailer nice.... fixed my issues 100 percent.



by:

Perfect, just what was needed. installation took 20-minutes, and back in the water !



by:

I purchased guide-on bunks to facilitate the loading of my pontoon from the lake onto my trailer. The hardware included two kinds of u-bolts. One kind is a standard u-bolt The other kind has an indentation in the center of the crossbar. The instructions showed that the u-bolts should be crossed when installed on the frame of the trailer.
But crossing the u-bolts is impossible if the frame is three inches wide. I learned that for frames that are three inches wide, the u-bolts should NOT be crossed. I learned this only by finding on U-Tube a demonstration of the installation. The instructions should have made this point clear.

On a separate matter, the representative who took my order, Bryan, provided excellent service.

I have spoken with my contacts at CE Smith and these should work for their guide ons, and they do need to be crossed for a correct install. The flat u-bolt should be mounted closest to trailer frame then the indented/formed on should be installed over the flat one.

    Yes, the CE Smith post style guide-ons # CE27620 will work on a Karavan jet ski trailer. The u-bolts will fit frames up to 3" wide and 4-1/4" tall.
