Galvanized Steel

Galvanized steel parts are hot-dipped in zinc after being stamped. This creates a coating that is typically 3 mil to 5 mil thick. This thick, all-around coating allows galvanized steel products to provide years of use without rusting or corroding.

Great, quality and easy to use and inst all.

I bought a 2007 16' Carolina Skiff for $3500 back in December. The dealer said there was nothing at all wrong with it and he went over it and winterized it. I finally got around to putting it in the water and saw that the bunk boards were in terrible shape, with one side rail guide-on falling off. I took it to a marina repair shop and was told it would be cheaper to buy a new trailer instead of replacing the bunk boards. I contacted Ashley at etrailer about buying a set of bunk boards and all of the brackets and hardware for it. $370.00 later I had a full set of bunk boards and guide-ons being shipped to me. I don't think I could find a new trailer for that price. It took longer to remove the old ones than it did to put the new ones on. About 3 hrs later I had a new trailer. These bunk boards and guide-ons fit my boat and trailer perfectly.
Thank you Ashley and etrailer for great customer service and a very good product at a really decent price.

every thing has been great on all that i ordered from you and your service was fantastic thank you for everything.



by:

perfect fit matches the original The U bolts were a little long but made them work as well could have used a couple more.



by:

What I loved: VERY solid construction. Never have to worry about this part giving out. Recommended u-bolts were a perfect match. Installation was relatively quick (counting removal of old roller parts and installation of new bunk hardware and bunks: just under two hours). Adjustable height of bracket and ability to change angle of bunk made it easy to match the fit of the new bunks to the hull.
Absolutely, would use this part and company again.



by:

These are good quality U-Bolts however I missed the fact they only have about 1.25 inches of thread. Trailer rails 1.5" and you have a whole lot of space to make up when mounting bunk rails. 5-flat washers and a lock washer bridged the gap. Just plan on an additional $3/bracket for the flat washers.



by:

Etrailer had by far the best prices when delivery was factored in. The entire order was packed well arrived quickly. I haven't installed any of the items but they look like great quality parts & will be a direct fit.
I highly recommend Etrailer.

Bunk board brackets, were made of quality and fit trailer frame well. Service and shipping was extremely good and fast, very happy with the customer service.



by:

GREAT Customer Service!! Seth worked with me to get the exact size and type of bolts needed for the job. Prompt delivery and up to date tracking. This is how a business should handle their customers. Bolts are heady duty galvanized. Will easily replace the rusted bolts that hold the bunk board brackets.



by:

Just received all of the brackets needed to rebuild my trailer bunks. Cost half of what the local marine shop charges for same parts. This is second order for boat trailer parts. Allways correct and shipped quickly.



by:

Always great service dealing with you guys, not a problem with any of my multiple orders. Keep up the good work. George J. always follows up with me to see if everything is good. Am using these u-bolts to mount motorcycle ramp to jet ski trailer, to allow more versatility.



by:

This product was as advertised and worked great with the bunk brackets I ordered. I could not have ask for a better fit.

etrailer’s service and product helped make a somewhat difficult task very manageable and satisfying when I finished. This will be my go-to site from now on!

  • Replacement Rollers For Wobble Rollers To Eliminate Marks and Gauging In The Boat Hull
    Since your main concern is the marks on the hull of your boat I recommend going to the Yates TPR Ribbed Wobble Roller. These rollers are constructed of thermal-plasticized rubber which is a non-marking, non-scratching material. It is stronger and more durable than traditional rubber while being softer and more pliant than polyurethane. You will need to find your shaft size to find the correct 5" Rollers. If you have a different size roller let me know what size it is and I can help you...

  • Maximum Height of Bunks On CE Smith Multi Sport Plus Boat and Kayak Trailer
    The taller of the two sets of bolster brackets that come with the # CE48870 are 12" tall. With the swivel bracket on top that is going to put you at 13". Add the height of the board on there which is 2" so that puts you up to 15". Now considering the crossmember and the slight bit of the bolster bracket that hangs down you'll be at around 11-1/2" just shy of the 12" you're looking for. To be safe, I would go ahead and get the CE Smith Double U-Bolt Bolster and Swivel Bracket Assemblies...

  • Switching From Rollers to Bunks on Boat Trailer for 1979 Mako 20

  • Recommended U-Bolts for Bracket Replacement on Boat Trailer With 3x3 Frame
    For U-bolts for your 3" x 3" frame you will want something that is slightly larger. If the measurements were listed as exactly 3" it isn't going to fit. What you need is the CE Smith U-Bolts - Galvanized - 3-13/16" Long x 3-1/16" Wide x 1/2" Diameter # CE15283GA. These U-bolts are the right size for your frame with a 3-1/16" width.

  • Will CE Smith Double U-Bolt Bolster and Swivel Bracket Assemblies - 10-1/4" Work on a 3,500 Lb Boat
    The CE Smith Bolster and Swivel Bracket Assemblies part # CE10191GA-4 do not have a specified weight capacity as it can vary by the strength of the u-bolts used in conjunctions with these brackets as well as how many brackets are used per board. I know this is frustrating to not have a specific weight capacity but unfortunately the manufacturer just does not provide this. If you feel you'll be exceeding the limits of the swivel brackets, you can always double up using multiple sets per...

    The diameter of the U-bolts that need to be used with the CE Smith Double U-Bolt Bolster and Swivel Bracket Assemblies # CE10190GA-4 is 1/2 an inch. If you do not have enough U-bolts, you can purchase 8 of them with the washers and nuts included with part # CE15283GA-8.

  • Tallest Bunk Bolster Brackets to Clear Trailer Tires on a Boat Trailer
    Your best option is going to be bolster bracket set # CE10196G-4 which is a quantity of 4 so if you wanted 6 you would need 2 sets and you would have a couple of spares should they be needed. These are 16-1/4 inches long with some adjustability due to the slotted holes. For u-bolts use # CE15283GA-8 (which is a set of 8 because each needs 2 u-bolts).

  • What are Benefits of Bracket Assemblies on Boat Trailer?
    Even if the boards can bear the weight of the boat, by concentrating the weight on a smaller, 3 inch surface, there is a greater risk to denting or deforming the hull of your boat compared to having the boat's weight spread out over a larger surface. To install your bunk boards, the assemblies you mentioned, the Bolster and Swivel Bracket Assemblies # CE10190GA-4 are the best overall option. They attach with a pair of U-bolts # CE15283GA-8 each for connection security, and both the brackets...

  • Torque for Installing Nuts of U-Bolt Kit # CE15283GA-8
    The correct torque spec for trailer suspension u-bolts will depend on the the diameter of the bolt. You will want to use the following depending on bolt size: 1/2" bolts: 45 ft/lbs - 70 ft/lbs 9/16" bolts: 65 ft/lbs - 95 ft/lbs 5/8" bolts: 100 ft/lbs - 120 ft/lbs 3/4" bolts: 140 ft/lbs - 160 ft/lbs Since the # CE15283GA-8 is a 1/2 inch diameter you'd want to go with 45-70 and you'd be good.
