Does it Matter Which Way a Double-Eye Trailer Leaf Spring Faces

Question

Question:

Are leaf springs directional. I am changing from single leaf to 4 leaf springs. There is a strap on one end of the leaf springs about the 2nd leaf and I see that also the manufacture has painted that eye on that end also. I am putting these on a tandam trailer.Which way should they hang.

If they are double-eye leaf springs, it should not matter which way they are facing. But if they are slipper springs, the eye end is at the front and the slipper is at the back. The springs that we carry are not marked as to which end is front and I have seen them either way on a trailer. I have included some links to suspension FAQs for you.

@DavidR Hello David, Great question. Install the double-eye leaf springs with the curve facing up. One end attaches to a solid mount, and the other connects to a moving shackle so it can flex. Line up the center bolt with the axle, and if one side is longer, it usually goes toward the back. The shackle should swing backward when the spring flattens. Check that the bushings are in place and not worn out. What kind of trailer are you working on?

Hey Henry, that's a great question but the answer is that it depends...it depends on if your axle is above the leaf spring or below it. If your axle is above the leaf spring it wouldn't affect the trailer height. If below it would raise it.…

Hey Richard! How did you measure your current leaf springs to get the 25-1/2" eye to eye measurement? We recommend jacking one side of the trailer up to get the weight off of them before measuring because they stretch out quite a bit over years…

Hey Mark, I looked up the specs of the spring you have now and found that it is a 24-3/4 inch long spring from eye center to eye center and for a 7k axle. So that means that the replacement spring part #EM28AJ that you referenced will work great as a…

You do want to measure the springs with the weight off of them because they will flatten out with the weight added. Over time, springs can flatten a bit and that is why you are getting the 26 inch measurement. Based on the measurements you provided,…

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,…

Comfort wise you'll be ok adding the 4-leaf spring item #TRU25FR over the 3-leaf spring item #e57SR just be aware it will slightly affect the ride height of your trailer. If your springs are above your axles it'll sit a little bit higher…

Answer 9

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.

The 4-Leaf Double-Eye Spring part #e44SR is what I recommend using to replace your Dexter Leaf Spring 072-078-00. It's the same length but a slightly higher capacity, 4,400 lbs vs. 5,000 lbs which is not much so it won't really affect the…

Hey Phil! Thanks for getting back to me with those measurements! We have a leaf spring that is an exact replacement but I am guessing it's the pricey one you referenced. It is the 4-Leaf Double-Eye Spring for 4,400-lb Trailer Axles - 25-1/4"…

I definitely understand how safety chain capacities and determining exactly what chain rating you need for your trailer can be a bit confusing. To keep it as simple as possible, safety chain requirements state that the breaking strength of EACH…
