Do Trailer Leaf Springs Have to Face a Certain Direction

Question

Question:

I have a trailer with brakes. Does it matter if the spring leaf clip is forward or aft of the Axel? I suspect the clip is there only for spring assembly, stacking of the leafs, but wonder if it might also have something to contribute when braking and torsion is added to the spring.

The clip that goes around 3 of the leaves of the 5-Leaf Spring part # e34SR that you referenced can go either in front of the axle or behind it. Either way would be perfectly fine.

I attached an FAQ on trailer suspension for you to check out as well.

Can you purchase the clips for leaf springs and install on both ends? Does the installed direction of the spring clip really matter? What is the purpose of the spring clip?

Leaf spring clips are not sold. If the are damaged, the entire leaf spring is replaced. Additional clips are not to be installed. Most sources say there is not a front or back, However, one of our suspension suppliers says that the clip side goes to the front, and every trailer I have ever seen has the clip to the front. My wild guess is that this is the beneficial orientation where the leaves are being held as a wheel is entering a pot hole or hitting an obstruction.

@LesD they are to hold your spring pack together when the trailer brakes are applied. Otherwise the axle wrap would want to separate them and cause extra wear and tear on numerous suspension components. Additionally the springs tend to get out of line with each other as they cycle

Since trailer leaf springs tend to stretch over time the key to picking out the correct replacement is to go with one slightly shorter than what your current one measures. So a 26 inch long spring would most likely be what you need. For a 2,000 lb…

There are no U-bolts to attach the slipper part, I recommend replacing your slipper springs with double eye springs. In order to do this you need to know the weight rating of your axle as well as the length from center eye to center eye so you can…

Excellent question. I had to think about this one for a bit and consult another person familiar with trailer assembly. Normally the band is placed forward of the axle on the trailer but it really does not matter which way the band is oriented.…

Both trailer tire sizes you reference, ST205/65-15 and ST205/75-15 share the same width (8-inches) but have different overall diameters. So you will want to insure that your trailer wheel wells/fenders have enough clearance for the larger tire. At…

I believe the hubs are for 2,000 or 2,200 pound agricultural axles which is why the springs look so different. These hubs are designed for very low speed applications (5 to 10 miles per hour according to HADCO) so if you plan on going faster than…

When using the 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles part #e27SR with the Single-Axle Trailer Hanger Kit for Double-Eye Springs part #APS4 you will need to space the leaf spring hangers 25-3/4" apart.
