Hey Cody,
The amount of leafs in the spring isn't as big as factor as you'd think. The more leafs the softer the progression will be when the spring is compressing. Less leafs will give you a stiff progression as the spring compresses. When you measured from center to center on your eyelets did you lift the trailer and allow the axle to hang to take the weight of the springs? If not, you'll need to so that you can get an accurate measurement.
Once we have that measurement we'll also... view full answer...
Grand Design does a great job listing the parts for their trailers but the one thing they don't list individually is the leaf springs. I can see that you have 7k axles on your Momentum 320G but you will have to measure the length to see if it matches. When replacing leaf springs you typically want the same capacity and the definitely the same length.
The # DX74XR is a little higher in capacity at 8k which is what you're looking for but we don't know if the length works. These leaf springs... view full answer...
The length Dexter posts for their leaf springs is the flattened length, so with the 072-042 having a length of 26" you would want to compare that to our 25-1/4" long springs as we measure their length with the spring relaxed. The 3-Leaf Double-Eye Spring # e57SR would be the size you want to look at. This is also a spring rated for a 4,000lb axle but it can be used and will just be a little stiffer and likely last longer than your current springs. You would need to change all your springs... view full answer...
There's no database of what size springs are on your Jayco trailer so you'll need to take a measurement. To start out with you'll need to jack one side of your trailer up to get the weight off of the suspension. The springs stretch out through the years of use so taking the weight off of them stops this.
Once you've done this you'll want to measure from center to center of the leaf spring's eye bolts and count the leaf's. The 5-Leaf Double-Eye Spring item # e34SR you were looking at measures... view full answer...
Hi Tim,
A half inch difference between your old springs and some new springs would be well within tolerance so you would not need to replace the equalizer. The equalizer end of the # e27SR will sit slightly more in towards to the center hanger but it's such a small amount that it won't make a huge difference. You will want to replace the U-bolts when swapping out the leaf springs since they get stretched when torqued down and shouldn't be reused. With you having a 4,400lb axle it should... view full answer...
Hey Eric, the 6-Leaf Double-Eye Spring for 5,300-lb Trailer Axles # SP-222275 could work but really to be sure you'd need to measure the length from center of spring eye to center of spring eye (unloaded), measure the leaf thickness, and find out what capacity your current leaf springs are.
If your current leaf springs are 24 7/8 from spring eye center to spring eye center (unloaded), have 1 3/4" wide leaves, and have a spring capacity of 2,650 lbs, then these'll work great.
If not,... view full answer...
So first I want to verify how you measured the leaf springs. On the etrailer Rust-Resistant 6-Leaf Double Eye Spring for 6K Trailer Axles # e88SR the 26" measurement is from center of leaf spring hole to center of leaf spring hole when the spring is relaxed. If you got the measurement off a model number it could be a different length since some measure leaf spring length when the springs are flattened. It that is the case you would likely need to consider either the 25-1/8" # e47SR which... view full answer...
Hey John,
You definitely weren't lying about those springs being flattened out. With them being flattened out they are going to be a bit wider so you will need a shorter eye-to-eye measurement than 26-1/4". My only concern is that the # e54SR at 25-1/8" is going to be a bit too short and have your shackle straps sit out too far, which will eventually lead to a bind up.
If this was a trailer we had in the shop I'd pull a few sizes and see what worked the best. Since we don't have that... view full answer...
Hey Mike, going to a higher rated axle leaf spring like the 5k option you mentioned is going to give you the best support to prevent the springs from wearing out again. For that we do have the part # e44SR which is 25-1/4 inches. This is a very popular size spring but you should still measure yours to be sure. view full answer...
The distance from the center of the eyelet to the center of the Dexter 6-Leaf Slipper Spring for 9,000-lb Trailer Axles # DX83QR is approximately 13-1/4". The flat length, following the curve of the leaf spring from the eyelet to the center is approximately 14". view full answer...
Hi David,
In order to find the correct replacement leaf springs for your trailer we'll need to know the eye-to-eye measurement of the spring. You'll want to loosen the lug nuts on one wheel and then jack up that side of the trailer by the frame to remove the wheel and let the axle hang. You'll then measure from the center of one eyelet to the center of the other eyelet to find the length.
The next step is to look at the weight capacity of the axle to determine the correct capacity springs.... view full answer...
Hey Patrick,
We can get you replacement double-eye leaf springs for your 2020 Grand Design Reflection 31MB, though unfortunately we don't have any way of knowing what specific ones you need. That said, it's pretty easy to determine, as all you need to do is measure your current leaf springs from center-to-center of the spring eyes, and you also need to know the weight rating of your axle (which should be printed on a sticker or tag on the axle itself).
Leaf springs also flatten a bit... view full answer...
A leaf spring being 1-1/2" longer is going to be to much of a difference to work properly for the trailer suspension. While it may bolt up the positioning of the axles will change by quite a bit and may bind up as the suspension travels through its range of movement. Typically I do not like to see more than 1/2" difference in the length of the leaf springs when you replace them if you are unable to find the same size. If you can let me know what length springs you have and how you are measuring... view full answer...
Hey Ryan,
You're right that leaf springs can flatten a bit over time, but I wouldn't go with a full 1/2 inch less. Something slightly shorter (1/4 inch or so) would be better, but otherwise, I'd stick with the 26 inch springs.
Just a reminder the measurements should be taken center of spring eye to center of spring eye as opposed to the full length, and while we don't have 25-7/8 inch leaf springs, we do have 26 inch springs, the 2,000 lb # e77SR, 4,000 lb # e22YR, and 6,000 lb # e94SR.

First, thank you so much for providing all the axle information on your 2007 Fleetwood Redline 33. The 4-Leaf Double-Eye Spring # e47SR is our closest match to the Lippert 702096 leaf springs that came on your trailer. Both are 4 leaves and the Lippert has a loaded length of 26" while our measurement of 25-1/8" is the unloaded length. You will want to replace all 4 leaf springs at the same time to ensure the suspension system under your trailer behaves properly. view full answer...
The 30" Slipper Spring # e89SR is our longest 4-leaf spring. I might be able to help you change out your springs with a different size that are more easily found if you can send me some images of your suspension setup with measurements from the hangers. view full answer...
Hey Kevin thanks for your question. There is not much downside to going with the 5,000 lb springs instead of the 3,500 lb. A higher rated spring may make the ride a bit more "chunky" at times, since the spring would not flex as easily. Other than that, the springs can definitely be upgraded as long as the eye-to-eye length matches. So if the current springs measure 25-1/4" long eye-to-eye when not under a load, the 4-Leaf Spring # e44SR will be the one.
Keep in mind though, that upgrading... view full answer...
Hey Larry, so I can help but I don't know exactly what spring you will need. We will need to know the axle capacity that his on your Forest River and the length of the spring. To get the length the best way is to remove it altogether but otherwise you can can jack up the frame of the trailer to get the load off the springs and then measure from bolt hole center to bolt hole center keeping in mind that springs tend to stretch a little bit as they wear out. view full answer...
Hello Crystal. It is possible to replace leaf springs with higher rated springs, as long as the eye-to-eye length of the spring stays the same. That said, adding higher rated springs does not increase the carrying capacity of your trailer. So even if you were to put a 2,500 lb each spring on a 3,500 lb axle, you will still be limited to the 3,500 lb capacity of the axle.
Also, adding a higher rated spring can negatively affect the ride quality. A higher rated spring is not going to flex... view full answer...
I would expect the eye to eye measurement to be shorter when you take the weight off of the leaf spring. It is hard to say how much shorter but 3/4" is certainly possible. Even if you remove the weight it will be longer than it was originally since they wear out over time so you need to account for that.
What I would do is take the flat measurement so you don't have to guess. For double-eye leaf springs, measurements are usually taken from the middle of the center bolt to the middle of... view full answer...
