Question

Question:

In the attached picture from your website, the rear shackle right side is sitting at an angle. Does the direction of this angle matter leaning forward, backwards, or vertical?

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 have issue as you go over bumps. If it is completely vertical or angled back toward the axle, then your leaf spring is not long enough and your suspension components will not move as intended giving you a rough ride at best and at worst failure of components. I've attached a suspension article to assist, but let me know if you have further questions.

I've attached a single axle hanger kit # APS4 that gives you compatible spring options for capacity and hanger distances.

I have a small trailer, but also another set of leaf springs. Can I mount them adjacent to the existing leaf springs (obviously adding another 2 supports for them, but on the same axle) to increase the carrying capacity?

I don't recommend installing an additional set of leaf springs on the trailer. This won't actually increase the trailer capacity (since you'll still be limited by the axle rating) but WILL create an extremely rough ride during travel.

I would avoid using vehicle leaf springs if at all possible because they are designed for the driving and load shifts that come with a vehicle as opposed to that of a trailer. Leaf springs are something that get replaced regularly so it's best to keep it as standard as possible so that it's easier to replace further along down the road.

Answer 3

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.

The Dexter 072-078-00 is a 2,200 lb capacity leaf spring. You can use a higher capacity leaf spring, however it won't increase the capacity of your trailer as the axle is still rated for that max capacity of 4,400 lbs. My recommendation for a…
