Video Transcript for Redline Trailer Suspension - Leaf Spring Suspension - E4139 Review

Today, we're going to be taking a look at the front, center, or rear hanger, for double-eye springs. This hanger can be used as a front hanger on single axle applications, and it can be used as a front, center, or rear hanger, on tandem or triple axle applications. It's going to fit 1 3/4" wide double-eye springs with 9/16" diameter eyes. It does work with a 9/16" diameter bolt, hardware sold separately. The unit's made from a sturdy steel construction. It measures around 3/16" thick.

It is a weld-on application, so this will weld directly to the trailer frame. The height measurement for a hanger is taken from the center of the mount hold to the top of the hanger. The height for this particular one is going to give us a measurement of about 4 1/4". The overall length, looking at about 3". External width is about 2 5/6" to 2 3/8".

Internal width, it's going to measure about 1 7/8 to 1 15/16", and then the overall height of the unit, that's going to measure about 4 7/8" tall. Then the holes on the unit, again, have that diameter of 9/16". That's going to do it for today's look at the front, center, or rear hanger, for double-eye springs.

Front/Center/Rear Hanger for Double-Eye Springs - 4-1/4" Tall - 9/16" Bolt Hole - E4139

Average Customer Rating:  4.9 out of 5 stars   (105 Customer Reviews)

Hanger can be configured to work in the front, rear or center position to suspend your double-eye leaf spring or equalizer.


Exactly what i needed. Same dimensions as the original. Might have even been a little thicker gage metal than my originals. I added angle gussets to all my hangers to hopefully keep them from breaking again.


These were purchased to assist with raising a dual-axle travel trailer. They arrived well packaged, and looked to be well made.They took readily to welding, so there was no issue with inferior material. The attached images show them being welded side-by-side to the frame rail extensions, then the entire assembly attached to the main frame.

After a year and more than six thousand miles under our 30 foot fifth-wheel, these show no sign of degradation. At this point, Ive quit worrying about them, and just keep rolling. Thanks, etrailer!

The products I ordered came extremely well packed in one large box. The spring hangers look to be in good condition and ready for welding, and the wet bolt kit for Morryde came with excellent instructions. Shipping was quick arriving at my house sooner than expected.


Fit and function was perfect


Good product. Just what I needed.


Great place to deal with, fast shipping, extensive emails, and they have the product. need this extra long spring hanger and they were the only ones I could find that had it. Rebuilding a tow behind dump trailer.


Fast shipping. Exactly what I ordered


Fit perfect and good quality.


Easy to order. Arrived earlier than expected. Product just what was needed.


Only place I could find them thanks etr ailer!


When I disassembled my springs and shackles to replace the worn items I discovered my hangers were not worn at all. I completed my rebuild of the suspension and had some welding done on the frame that Terry did not complete back in 1996. I ended up using the hangers as barter for a portion of the frame rework.
The suspension parts I used from you folks fit and worked as expected and we took our 1996Tterry 5W to Texas this spring and had a good time.
Thank You,
Jim Ferry
Thornville, Ohio


Perfect match, and the info on the website helped me get the spacing right (factory hangers weren't welded on right so the springs were always cocked)

Hi Patrick, still happy as a clam with my order. I took an old camper trailer frame and cut it down to make a canoe kayak trailer. Your info on the web site and parts helped A LOT. We have used the trailer several times. Good stuff. I have 5 trailers, yall are my go to place for parts.

Parked in the middle of the Mojave desert I noticed that the wheels and tires
on one side of my old Crusader travel trailer were quite close together, within
about two inches of touching each other. On further inspection the welds on the
rear axle spring hanger had failed, leaving 2, 5" pieces of strap steel hanging on
the leaf spring. Was trying to figure out a fix without calling a mobile welding
outfit, when I entered "travel trailer spring shackle" on my Verizon tablet, and
There you and the exact piece of steel I needed were. Had no idea that it was
Such a common part. Cleaned up the frame with a grinder and drilled two
Holes. Two grade 8 nuts, bolts and lock washers. Saved about 15 times the
Cost of the part and shipping. Bravo!!


Everything arrived in a timely manner and was well-packaged.
My only disappointment was not being able to purchase 4-1/4" front hanger brackets in a kit. I was forced to purchase the kit with 3-1/4" brackets and order the 4-1/4" brackets separately.


Heavy duty well built straight bends welded nicely. Quality product

This is a quality product that goes on straight and true no binding thick and sturdy
Larry - 03/17/2021


Perfect fit and no one else had this specific size needed to match my trailer. I would purchase again if the other side breaks an ear off (let's hope not)


Thank you for all the help on the phone to get the right bracket hanger.

Product has preformed well no issues
Darron M - 10/25/2020


Honestly don’t know about the shackle hanger yet but I feel fairly certain it will do the trick. However, delivery and customer service have been excellent!!


The product itself is excellent, unfortunately somewhere the incorrect label was placed on 2 inch wide spring hangers and the correct appllicationfor the part number is 1-3/4". E-trailer is correcting and providing a shipping label to return the others. Slight delay but sometimes that stuff happens. No worries. The free shipping on $150 orders make up for a lot on heavy parts.


It was just what I needed. Installation was typical. This part replaced a broken one on a fifth wheel trailer. Shipping was great!


I try to purchase local when I can but the local trailer places charge from 2 to 4 times what I can get parts from etrailer. So I come to etrailer for all my trailer parts. Service is great and shipping it quick for items in stock. I currently have a few things on backorder that are taking some time.


Thank you for the timely delivery!


Good product. I needed to lift our 38 foot fifth wheel about an inch and replaced the 3 inch mounts with these 4 inch and accomplished our goal.


Great product worked perfect for replacement on tandem axle trailer. Had a spring perch broken.


The hanger on my trailer was separating from frame. After torching off the old hanger, welding in a support plate- this was a simple replacement. Still holding up well 1 year later.

  • What is the Inside Width of Trailer Leaf Spring Hanger E4139
    If the outside width of hanger # E4139 is 2-5/16 inches and the metal thickness is 3/16 of an inch then you would take 2-5/16 and subtract 3/16, and then subtract another 3/16, to get 1-15/16 inches. It is meant to be used with leaf springs that are 1-3/4 inches wide. I made a picture showing these measurements for you.

  • How to Install Spring Hangers on Single Axle Trailer
    Spring hangers are intended to be welded on. Although you could drill holes in them and bolt them to your trailer, this would affect their capacity to some unknown degree and so this is not recommended. A local trailer supply shop will be able to do this, or there may be an automotive shop near you that is able to do the welding. Since there is not a lot of material to weld, the cost should not be excessive. You may want to review the linked article on trailer suspensions to get a more...

  • Troubleshooting Sagging Suspension on 1990 Stratos Trailer
    The usual minimum recommended clearance between the top of a trailer tire and the fender above it is 3 to 4 inches. Normal trailer suspension travel requires this much clearance. It is surprising that original OEM wheels and tires would provide for only 2-inches of clearance. By chance, were the fenders changed out? You could have worn sagging springs that can no longer suspend the trailer deck at the correct height. If the original springs are still on this trailer they could certainly...

  • Why Do Trailer Center Suspension Hangers Sometimes Hang at Different Heights
    Ideally you want the leaf spring to sit as level as possible on your trailer. Since the equalizer used on the trailer can vary in height sometimes the center hanger will set level with the others or it can hang lower depending on the equalizer used. Going with taller hangers in general will lift the trailer and would give you more axle clearance. The hangers should not end up flexing. I attached a link to a page that has a chart at the top that has all of the hangers we carry with their...

    I went out into our warehouse and pulled a Front/Center/Rear Hanger for Double-Eye Springs, part # E4139, and measured the outside width of it. It measures 2-5/16 inches from the outside of one side of the # E4139 to the other side. Check out the picture to the right to see this measurement.

I went out to our warehouse to measure the thickness of the metal on the # E4139 and it came out to be 3/16 inches thick.

  • How To Choose the Correct Replacement Trailer Leaf Spring Hanger
    In order to choose the correct replacement trailer leaf spring hanger you simply need to measure the inside width and length from top to center of mounting hole. The majority of double eye trailer leaf springs will measure 1-3/4" wide so this measurement is not as important as the distance from the top of the hanger to the center of the mounting hole. The Hanger for Double-Eye Springs part # E4139 for example measures 4-1/4" from the top of the hanger to the center of the mounting hole. I...

  • Best Way to Raise Trailer With Square Axle
    There are not over/under kits for square axles, so you really only have a couple options. One is to replace your axle with a round axle and use an over/under kit, while the other is to install longer hangers, such as the - 4-1/4" Tall # E4139, which is for double-eye springs (which is what I assume you have because you mentioned an over/under kit). You would need to have your current hangers removed and welded on by a professional welder, but this is the best option to give you added height...

  • Is There Supposed to be Play Between Hangers and Leaf Springs
    There has to be a bit of play between the leaf spring bushings and the hangers so that the suspension components can move freely as needed. If you torqued down the bolt to the point the hanger flexed in and prevented movement you'd have a very harsh ride quality since the suspension would be ineffective.

  • How to Add Lift to Square Axle With U-Bolts
    One inch of travel is not much but if there isn't contact being made you will be alright. Adding lift is not dangerous but since it is a square axle that uses U-bolts the best way to do that is going to be with taller hangers like the Front/Center/Rear Hanger for Double-Eye Springs - 4-1/4" Tall - 9/16" Bolt Hole # E4139. You would need to have your current hangers removed and then welded on by a professional welder to accomplish this.

    The tallest spring hangers we have in a 9/16 eye diameter are the Redline item # E4139 you were looking at. If you want to go to the 5 7/16 inch hanger you were referencing you will need to upgrade to 3/4 eye diameter leaf springs. If you decide to upgrade your leaf springs to use the taller hanger please email me and I would be happy to make a recommendation.

  • Lift Kit Adding 2" For 1-3/4" Square Axle 5x8 Trailer.
    With square axles, neither of our over/under kits will be a fit to raise the height of the trailer so another option is to use longer hangers for the leaf springs. You will just want to confirm the hangar height. You may be able to use a hanger like part # E4139. This hanger is designed for double-eye springs and is 4-1/4 inches tall. The old hangers will need to be cut off and the replacement hangers welded on by a professional.

    There are limited ways to add height to a trailer, especially the amount you are looking for. This is especially true because you have already flipped the axles on your Keystone Hornet. The only other way you can gain height is to cut off your current hangers and have longer ones professionally welded on and the longest we carry are the Front/Center/Rear Hanger for Double-Eye Springs - 4-1/4" Tall # E4139 and the Center Hanger for Double-Eye Springs - 5-7/16" Tall # 115919.

    Since you have only moved things ever so slightly using a longer hanger like the Front/Center/Rear Hanger for Double-Eye Springs - 4-1/4" Tall part # E4139 will give you the desired effect and give you the clearance you need. You will want to use one at each connection point so at the end of each spring and above the equalizer.

    It is possible to have a center spring hanger that will be longer than the front and rear hangers.

A longer center spring hanger is normally used in conjunction with an equalizer. The equalizers are designed to transfer the load from one axle to another when the trailer goes over a bump.

  • Lift Kit Recommendation for Tandem Axle Trailer
    I have a really great and easy solution for a lift kit with the part # LC407131 but you can't change the height of the center hanger/equalizer to create more lift as this would change the angle of the leaf springs from being level which will negatively affect the life of the suspension and handling. The part # LC407131 gives you an easy to install 2 inch lift for both axles that doesn't change your leaf spring angle.
