Replacement Shackle Links For Boat Trailer

Question

Question:

Greetings, I am looking for shackle links or a one pice shackle for my boat trailer. I have 1-3/4inch wide double eye springs with 3-1/8inch center to center shackle links. I need to get tires a little further away from fender brackets. Im wanting to find a shackle that has a 4inch to 4-1/2inch center to center distance. Any suggestions? Thank you

The longest shackle straps we offer are part # TRSL350, and those measure 3-1/2 inches hole center to hole center.

For more clearance you may want to install longer hangers. Although these may be a lot more work because you would have to remove the old hangers and then weld new hangers in place, they may give you the length you need to move the wheels away from the fenders. I have attached a link to out product page of the hangers we offer. You can use the menu at the left of the page to filter the hangers we have available by length.

You might also want to see if there is a way to move the fenders higher on the trailer by relocating the brackets.

Answer 1

It really just depends on what you are looking to get out of the bushings. Bronze bushings, like part #K71-291-00, will last longer but are more noisy and it is recommended to use wet bolts like part #126B2 to keep them lubricated. Nylon bushings,…

Longer hangers will not prevent the shackles from flipping. If this has always happened or if the springs are new then they are too short. If it happens only when your trailer is empty then not enough weight/tension to keep shackles in place so they…

There is no set angle, but you want to leave enough room for the suspension to articulate. By looking at the photo, you will indeed need to move the rear hanger back a bit. The shackle strap be much closer to vertical, as shown in the diagram…

The Shackle Strap part #TRSL350 comes as a single strap. There should be 2 shackle straps per spring on a single axle trailer. You would need to order 4 of the part #TRSL350 for a single axle.

I contacted MORryde and this does happen from time to time as the weight of the trailer can spread out the axles due to downward pressure on the springs/suspension. Odds are the 35" wheel base #MR27ZR will be the correct one for you, but they…

Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are…

To correctly measure a leaf spring, you'll want to jack the trailer up on jack stands so the axle is hanging freely, then measure directly across from the center of one spring eye to the other, as shown in the provided diagram. The height of the…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

Answer 9

Yes, axle spread and wheel base by definition are the same measurements. You will measure from the center of one axle to the center of the 2nd axle to determine what you axle spread is. This may be difficult as some wheels and covers will make this…

Answer 10

Well shackle length is mainly based on the height difference between the front and rear hangers. The rear hanger normally doesn't hang as low as the front so that the shackle can offset the difference and add the ability to move. What is the…

The absolute best cushioned equalizer that fits the dimensions you mentioned having would be the MORryde ALLTREK 4000 part #MR89DR as this is only option to provide vertical and horizontal cushioning. This would make a big difference and you'd be…

Answer 12

For a single axle trailer, you want the shackle strap to be able to move so that you have the spring deflection needed for your suspension. Angled like the photo or even almost vertical is fine you just don't want the shackle strap to bind and…
