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...
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...
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...
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...
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 Eugene, you'd want a distance of 54-1/4 inches from the front to rear hanger centers. Basically to ensure you get the right shackle angle you need the distance between the spring hanger bolt center and equalizer bolt center to be about 1/8 inch less than the spring length. 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...
Hi Jonathan; we do not offer an axle in the dimensions you have, so you have a couple options. One is to have an axle fabricated for you, with the other option being the 2,000 lb Timbren Axle-Less Trailer Suspension w/ Idler Hubs # A20RS545.
This is an independent suspension that doesn't use an axle beam, and bolts to the frame. view full answer...
I would be happy to help but first you will want to take some measurements of the hangers and shackle straps you currently have to determine which ones you'll need. Longer or shorter on the shackle straps and hangers will change the ride height of your trailer.
The Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers item # K71-358-00 would work great with the 5-Leaf Double-Eye Spring item # e34SR you're purchasing. The included shackle straps have a length from center of... view full answer...
What you read is correct. You have a 3,500 lb Lippert axle with an 85" hub face and a 68-1/2" spring center measurement. I do have a solution, but unfortunately we do not carry a standard axle with these measurements. What I can offer is the Timbren Axle-Less Trailer Suspension w Electric Brakes # A35RS545E. This system is universal so it fits any frame width. It would also replace your existing leaf springs and upgrade you to an independent suspension. view full answer...
Hey Ethan,
In order to find the correct replacement leaf springs, shackle straps, and equalizers for your trailer you'll need to take a few measurements first. You'll want to lift one side of the trailer by the frame and let the axles hang, remove the wheel, and then measure each component how I have depicted below. You'll also want to look at the axle tube for the axle tag sticker to get the axle capacity. Once we get some measurements on your components and we know your axle capacity... view full answer...
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 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...
Hey James,
If you have standard equalizers with a 5-3/4" horizontal and 2" vertical measurement then the Dexter E-Z Flex Suspension Kit # K71-652-00 would be the correct replacement for you. If you're saying that you already have those and are wanting something else then you can go with the Equa-Flex Cushioned Equalizers # LC279687. These have a 5-1/2" horizonal and 2-1/2" vertical measurement so you'll probably have enough slack in the shackle straps to accommodate this difference without... 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...
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...
Hey Marty,
There unfortunately isn't a guide to tell us the part numbers used on your trailer so I'll need you to take a couple of measurements to get you the correct parts. You'll want to start by lifting one side of the trailer by the frame and letting the axles hang. With the wheel off you can measure the length from center to center of the leaf spring eyelets.
To find the right bearings and grease seal you'll need to remove the hub and check if the bearing and grease seal numbers... view full answer...
Since you have a 7-3/4" equalizer you are going to want to use the Dexter Heavy-Duty Suspension Kit # K71-449-00 you found. While most trailers who use this size equalizer will have a 35" axle spacing it is more important to match the dimensions of the equalizer than the axle spacing. This is due to trailer manufacturers not having to stick to specific regulations about dimensions. The kit includes 2-1/4" shackles which is going to work for your application.

For a 26" long replacement spring, I recommend the 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles item # e94SR. This spring works with 6,000 lbs axles and each spring has a 3,000 lbs capacity.
To confirm this is the correct spring you will want to measure your current springs with the weight off of them. They'll stretch out over time so the best way to get an accurate measurement is to jack up one side of your trailer and measure the springs from eye bolt to eye bolt.
