You likely have 1/2 inch studs on the trailer hub based on your tire size. For 1/2 inch you will want to torque the lug nuts to 75 - 85 foot pounds.

For 9/16 inch lug nuts torque them to 135 - 145 foot pounds.

And for 5/8 inch lug nuts torque them to 175 - 225 foot pounds.

You want leaf spring shackles to be at a slight angle as that prevents the springs from flipping around to the other side of the equalizer over uneven terrain. I attached a picture that shows what the angle is typically like.

Answer 7

The hub, such as the Dexter #8-219-13UC3 doesn't care which lug nut you use, as long as it's compatible with the 9/16 inch wheel stud diameter. The wheel itself is what dictates whether a coned lug nut is needed and what angle the cone needs…

You most likely will have a 60 degree cone. That is the most common. I included a picture that shows where the 60 and 90 degrees are being measured. It can be hard to tell with the naked eye unless you have one of each next to each other to compare.…
