Features to know about

Smoother Ride Over Rough Roads: 4-Leaf Spring Flexes to Absorb Shock

Rough pavement and uneven terrain can beat up a trailer’s suspension, but this 4-leaf double-eye spring keeps things steady. With a 3,500-lb axle capacity and 1,750-lb spring capacity, it flexes to take the edge off bumps and jolts. The spring’s multiple steel leaves work together to smooth out the ride, reducing bounce and wear on your trailer so it stays level and controlled mile after mile.

Photo of the etrailer 4-Leaf Double-Eye Spring for 3,500-lb trailer axles showing steel leaf construction and double-eye ends with bushings.

Reliable Suspension Support: 27" Long, 1-3/4" Wide Construction

A sagging or stretched spring throws off alignment and stability. This spring restores your trailer’s proper ride height with its 27" length (eye-to-eye, unloaded) and 1-3/4" width. Each 3/8"-thick leaf provides balanced strength and flexibility. It’s built to handle the consistent load of a 3,500-lb axle setup, giving you dependable suspension geometry for secure towing.

Smooth, Quiet Movement: 9/16" Nylon Bushings Reduce Friction

Creaks, squeaks, and metal wear are common with old bushings. This spring comes ready with nylon bushings installed in each 9/16"-diameter eye. The nylon material cushions movement and cuts down on metal-to-metal contact, so the suspension moves freely without noise or premature wear.

Ready to Mount: Works with Standard Hangers and Shackle Straps

The double-eye design fits right into standard hanger and shackle setups. One end mounts to a welded hanger on the frame, and the other connects to shackle straps or an equalizer. Whether you’re refreshing a worn suspension or replacing both sides for even support, this spring installs cleanly to restore proper function and tracking.

Amazing to be able to follow the shipment from order entry to every shipping location, the time at each location it was received, the time it left each location, until it was on the UPS truck and received at our home at the day promised.

I ordered the wrong springs. I contacted “Paul” who is generating a return label. I’m being charged [XX] on a purchase of [XX] for the springs needless to say no more e trailer for me. A local shop had the right springs at [XX] each



by:

I'm happy with the product and speed of shipping.

There was a clerical error on their side. I know this because I called this morning. Whoever placed the order misspelled my email. So I didn't receive a confirmation, invoice, or tracking number for a critical overnight order.

Instead of putting "Yahoo.com", they entered "Yaho.com" so I didn't receive any follow up info.


It will not stop me from making future orders.



by:

Great product. My fault by ordering too short. Paul B. Worked with me and had a shorter and heavier version in the mail.

Trailer sticker for GVW is unreadable so I was in SWAG mode on leaf weight. Product looks great though, just mot enough clearance between tire and fender.
PAUl B is very helpful. After the springs, on to the full brake system replacement.

Springs were great, customer service in finding the right length was outstanding as the trailer manufacturer (Keystone) did not provide adequate documentation and could not verify the model using the VIN. Shipping was free and amazingly fast for such a heavy item.

Fits like a glove just what I need

  • How Can I Determine Hanger Spacing For A 27" Long Leaf Spring e97SR?
    Hello James, thanks for reaching out. I can provide some rough guidelines for you, but there is not a "set in stone" hanger spacing for a 27" leaf spring like part # e97SR. Generally, for a single axle setup, your hanger spacing for a 27" spring would be between 25-1/4" and 26-1/2". I can't give you an exact number because the hanger spacing also depends on what size shackle straps and hangers you are using. Even if we knew all that, we can still only provide rough guidelines to go by....

  • 3,500 lb Rear Axle is Hitting Car Trailer Frame Are New Leaf Springs Needed
    Hey Henry, Really appreciate the photos as that made it easy to see what the situation was, and yeah, that's definitely an issue as the axle should not be hitting the frame like that. New leaf springs are a good idea as yours seem a bit long in the tooth (so to speak), but I'd also get an over/under conversion kit. The kit will move your leaf springs to the top of your axle, creating more space from the frame. I assume since you mentioned a 7,000 lb trailer that you have 3,500 lb axles,...

  • Replacement Leaf Springs and Shackles for 2014 Evergreen Amped 28FS Toy Hauler
    MORryde does have a suspension upgrade kit that I highly recommend. It comes with 1/2" thick shackles, along with wet bolts and bronze bushings. You will want to choose a kit based on the length of your current shackles. For 2-1/4" you need the # MR46ZR and for 3-1/8" the # MR76ZR. For replacement leaf springs you will need to know your axle capacity along with your spring eye to spring eye measurement. Your current leaf springs will be slightly elongated since they flatten over time so...

  • Determining The Correct Replacement Leaf Springs For A 2021 Keystone Passport Grand Touring TT
    You could potentially replace your leaf springs with a larger capacity spring but will need to match the length of your current leaf springs to avoid having to remove and reinstall the hangers and rest of the suspension system, which is a giant hassle and a lot more costly than just replacing the springs. If you have double-eye leaf springs you'll need to measure from the center of one eyelet to the center of the other. If you have slipper springs then you'll need to measure from the...

  • Recommended Leaf Springs for a 2022 Forest River Vibe Trailer
    Hey Margarita. What specific model is your 2022 Forest River Vibe trailer and how did you get the 27" measurement on your leaf springs? You can add this information, along with any other questions you have, where it says Add Comment. Leaf springs like to stretch out over years of use so the best way to get an accurate measurement for replacements is to lift one side of the trailer up. Lifting the trailer up gets the weight off of that side of the leaf springs and you'll be able to get...

I do not have a database that supplies me with what is on what trailer, in my research I see that the 2015 Karavan double PWC trailer, model WC-2450-84-L, is equipped with a single galvanized steel spring axle. This axle has a Gross Vehicle Weight Rating (GVWR) of 2,935 lbs and a carrying capacity of 2,450 lbs., but uses 3,500 pound parts.

  • Availability Of 30-1/2" Long Leaf Spring For 3,500 lb Axle
    Hello Richard, I do appreciate you reaching out, but I am sorry to say that we do not offer the leaf spring you are looking for. The closest thing we have for a 3,500 lb axle is the 4-Leaf Double-Eye Spring # e97SR which is 27" long so this would not be a suitable replacement for you, at least not without major modification to the trailer. Your best bet here will be to reach out to a leaf spring manufacturer like Dexter and see if they have anything that matches your specs.

    Hi Josh; what you have is a Lippert 3,500 lb axle with an 85-1/2" hub face measurement (length) and 70" spring center measurement. All of our 3,500 lb axles are too long to replace what you have so I would reach out to Lippert or Dexter to see if they have a replacement that matches. We may have leaf springs but there is no way for me to identify them with that information. We already know the capacity so you will need to measure to find the right ones.

    Hello Loren, I can help you determine the right replacement 3,500 lb or 4,000 lb double-eye leaf springs for your Keystone Bullet, though we don't have any way of knowing off-hand what specific ones you need. It's easy to find out though, as you just need to measure your current leaf springs from center-to-center of the spring eyes. Keep in mind leaf springs also flatten out a bit over time, so go with ones that measure a touch shorter than what you currently have. For example, if your...

    Hey Shawn, Without accurate measurements there unfortunately isn't any way to help. We don't have any way of knowing what leaf springs are on any specific trailer so you'll have to measure them. While it won't be exact, it's really the only way to do it; the best would be to jack up the trailer and measure them without a load if at all possible, but if you can't then just measuring them as-is can suffice. Since they're flat you'll want to take ones that are a bit shorter than what you...

    Hi Dan; is there a tag on the axle? That would be the only real way for me to identify it for sure. I'm guessing you would have an old metal tag which should have a serial number. You could also check on the axle itself for a serial number engraved on one of the ends closer to the spindle if the tag isn't there. If you add this information in the comments below I will reach out to the manufacturer if they're still around to identify the axle. Also, # 58846 is a part number corresponding...

    Hey Kyle, first of all congrats on the trailer! It might look wrong but don't worry it's not. Over time, leaf springs will flatten and elongate causing them to measure a bit longer than when originally installed. Since we are talking about less than an inch here of difference, I'd say with good authority that that's what happened. To double check that you have the right measurement, you're going to need to let your trailer's axles hang free and measure the eye to eye, the width, and the...

Our 5,200 lb axle springs will be more like 24" or 25" long so much to small for you. The 27" long spring # e97SR is rated for a 3,500 lb axle so not heavy enough.
