Double-Eye Leaf Spring Basics

Leaf springs, as you probably know, make up an important part of your trailer's suspension. Their main purpose is to absorb road shock as you travel, as well as allow your axle(s) to move independently of the rest of the trailer.


Double-Eye Spring Parts

To mount this leaf spring, you'll need hangers welded onto your trailer frame - which you probably already have in place - as well as shackle straps and a suspension bolt. It's a good idea to replace your existing straps and bolt while you're under there working on things because they tend to wear out quickly. One thing that could help keep them from wearing out too fast would be upgrading to galvanized or zinc-plated hardware. Doing so will boost the corrosion resistance and, therefore, the longevity of your trailer.


We also always recommend replacing both of your springs at the same time because it's not unusual for leaf springs to sag and elongate over time. If you replace just the one, there's a good chance that it won't match your existing spring on the opposite side of your trailer, and that can mess up your alignment.

  • Need New Leaf Springs For 2021 Grand Design Momentum 397
    Hello Steve, thanks for reaching out. In my honest opinion, leaf springs are leaf springs. There is not going to be a noticeable difference in quality or longevity between the different brands. As long as the length of the spring is correct and the weight rating is correct, you will be just fine. I see you were looking at a 24-7/8" long double eye spring for an 8,000 lb axle. Our most cost effective replacement for that is the following: - 7-Leaf Double-Eye Spring for 8,000-lb Trailer...

  • Will 8k Leaf Springs Lift Trailer With 7k Axles
    Hi Greg; leaf springs aren't typically used to raise a trailer. However, if the # EM28AJ matches your current leaf spring measurements, and your current leaf springs are 3-leaf, and the leaf springs are sitting on top of the axle, that would push you up by 1" with the 1/4" leaf thickness. Assuming this is a tandem axle trailer the other option would be to add the Correct Track # RR55QX. This kit extends your hangers so you don't have to cut them off and weld on new ones for a lift.

  • Recommended Double-Eye Leaf Spring for 8,000 lbs Axles
    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 of use. The 24-7/8" Long 7-Leaf Double-Eye Spring for 8,000-lb Trailer Axles item # EM28AJ will shorten up your suspension if you actually need 25-1/2" leaf springs so I would not recommend using these. We do not have the Hydrastar E7K-T9 kit...

  • How Tall is the Leaf Stack on the 7-Leaf Double-Eye Spring for 8,000-lb Trailer Axles EM28AJ?
    Hey Richard! I went out to the warehouse and measured the leaf stack on the 7-Leaf Double-Eye Spring for 8,000-lb Trailer Axles - 24-7/8" Long item # EM28AJ. It measures 2-1/2" tall. If you have any additional questions feel free to throw them into the comment box below.

  • Is There a Torque Spec for Install of Trailer Leaf Springs
    Hey Henry, with leaf springs like the part # EM28AJ there isn't a torque spec for the shackle bolts that secure them as they need to be able to move freely. So the trick is to use lock nuts so they won't back off. So using them snug them up by hand with a wrench and then back off 1/4 turn to allow the needed movement.

  • Are the Spring Eyes of the Double Eye Spring # EM28AJ Misshaped
    Hey Dean, that was a one time issue that most likely was damage that occurred on the spring in shipping. The eyes of the Double Eye Spring # EM28AJ that you would order would be solid and there won't be any issues.

  • Replacement Leaf Spring for Momentum 350G Fifth Wheel
    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 replacement since it's correct size and also for an 8k axle like you are wanting to give you more suspension support.
