Video Transcript for Review of TruRyde Trailer Leaf Spring Suspension - Shackle Links - TRSL225

Hello everybody, this is Jeff at Today, I'm gonna take a look at this 2 1/4-inch long shackle strap. Now this shackle strap will connect your double-eye spring to the rear hangar of your single axle trailer or to the A equalizer of a multi axle trailer. Basically using this, it'll shackle the two components together, instead of bolting them directly. It allows for the necessary pivot of the springs. This is a steel construction.

Few specs on this. Now, the length, when we say it's a 2 1/4-inch. It's not the overall length. When they talk about the length on a shackle strap, it's the measurement from the center of this hole to the center of this hole. So if we take our ruler and if we go center to center, you can see there's your 2 1/4-inch measurement.

Now, the overall dimension from one end to the other, 3 1/4 inches long, width on it, 1 1/4 inches wide, and 3/16 of an inch thick. And the two bolt holes on here, the diameter of those bolt holes are 9/16 of an inch. But that should do it for the review on the 2 1/4-inch long shackle strap.

Had a leaf spring break on my off-road trailer in Mexico. Left it at a boat yard until I received the parts from trailer & returned to replace. Only took 2 hrs to replace both leafsprinhs, shackles, bolts etc. And we were back on the road.


Quick delivery and exactly what I needed to repair a broken shackle (which happened when the E-brake was triggered).


Etrailer has a top rate operation! Their phone associates are professional and knowledgeable and their site is full of resources to help you diagnose issues and select the right parts.


Before and after installation

I used the Camper in the Summer during the Holidays , No problems Every Thing is still Working Fine


A perfect match to the original shackles


Just what I ordered, and the quality looks to excellent.


Right size and dimension works great


great springs, well constructed. Size was exactly what was advertised.


Pat from etrailer helped me enormously with this purchase. Most of the 2 1/4 inch shackle plates I found for sale were 1/8 inch thick, but on my triple axle trailer the originals are 3/16 inch thick. I know it's not much, but I couldn't imagine going to a smaller (even slightly) shackle plate given that I was shopping for new ones after two of them broke! Anyway, Pat called the manufacturer the following morning when they opened, then called me to confirm they were the right thickness. What great customer service! The plates arrived quickly, and fit perfectly. My camper was stranded in front of my suburban home for fear the suspension would collapse if I towed it to be repaired. Finding the exact replacement parts allowed me to repair the camper myself and tow it back to storage before the neighbors got too upset. The plates were in good shape when they arrived, and the holes had a slight bevel to accept the ribbed shoulder of my replacement bolts. I expect many years of service out of these new shackle plates.


Very durable, my trailer is back on the road again.!!!


I ordered several items for my boat trailer to replace the springs and renew the related hardware. There was a little glitch, as the springs were sold out in inventory. The etrailer staff quickly advised me of this issue and offered alternatives. However, my order was shipped was shipped within a few days and arrived as ordered. I will definitely use etrailer again.


After suffering a major incident on the highway where 3 of the 4 tires were destroyed along with the rims and some suspension parts, I needed parts fast and correct for my trailer. These wheels, along with the other suspension parts, where inexpensive, well built, accurately described, delivered quickly, and exactly what I needed to get my trailer back up and in operating condition again.


replaced the suspension on my 5th wheel--all went well and now I am much releived to lub with a grease gun and not a oil can. one of the wet bolts was defective--I called you sent one out quickly--thanks


Just exactly what I needed!



After one year and about 15K miles pulling loads of around 7K I couldn't be happier! These parts were a tremendous upgrade to my existing parts.


The products I ordered are exactly as described, and finding what I was looking for was very easy. The ordering process is also very easy, and shipping was much faster than I expected. In fact, the folks at etrailer went out of their way to make that happen. The prices here are more than fair as well. The folks here go out of their way to help with accessories and product information to help insure you get the right parts for the task at hand.

Customer service is second to none here, and it is indeed very refreshing to see a company who "genuinely" cares about their customers satisfaction as the folks at etrailer do!

I will try to come back and submit photos once I complete the repairs.


Straps are thinner than the originals. Seems to be a common complaint I overlooked before ordering. I will be concerned about premature wear and looser suspension until I get these replaced with better quality parts. Hopefully the wet bolt kits will lessen the wear.


Bought 4 leaf springs, bolts, bushings, etc... Needed it next day, and the shipping cost more than the parts, which tells me the parts were a great price. All was well, on time, and to order. The only problem was I should have ordered two more shackle bolts... but that's on me. Thanks Guys and Gals. I am a happy 62 year old Marine Vet back on the road!


Good product but the description is a bit confusing. The shackle is actually 3 1/2" long and the bolt holes are on 2 1/4' centers. Dexter calls this a 3 1/2" long shackle; eTrailer calls it a 2 1/4 long shackle. The diagram clears up the confusion, but it would be helpful to the uninitiated (myself) if the method of measuring was the same.


good heavy duty shackles.

Doug V.


Everything has worked great! Thanks for great parts, prices


So glad we found greasable bushings, bolts and nuts to replace plastic setup on our 5th wheel while traveling. If you have Forest River you need to replace with greasable. Repair shops just do plastic if you don't know better and send you on your way!! Awesome staff and quick shipping Quality parts


Just received the shackle straps and bolt. They look excellent and superior as the originals were only 1/2 " dia. and strap holes elongated by 1/4 ". One was worn thru. Also, straps are at least 1/32 thicker than originals.

You phone person that took the order did an excellent job and very patient. First trailer suspension I have overhauled so some difficulty in describing what I even needed.
Should be back on the road in a day or so. tks bob


Fit perfectly, thank you.


Erika was super helpful. Really helped me get the correct parts the first time. I will always use etrailer from now on!!

A+++ in my book!

Ed R.


SUPERB!!!!!!!! Erika at E-Trailer is AWESOME!!!!


First time ordering from this company information on website is very useful tracking number email was awesome being able to look on the map and see exactly where my order was at will be ordering from this company for years on in now


Works great. Completely restored all the suspension components on my 2000lb axles and these fit perfect.

  • How to Pick Out Correct Shackle Length for Trailer Suspension
    Well shackle length is mainly based on the height difference between the front and rear hangers. The rear hanger normally doesn't hang as low as the front so that the shackle can offset the difference and add the ability to move. What is the height difference from the frame of the trailer to the hole on both hangers? With that we can see what would work best as a shackle. You want to go with the shackle length that allows the spring to sit as level as possible. The most popular size is...

  • Are Trailer Leaf Spring Shackles Supposed to be Angled or Totally Straight
    You want leaf spring shackles to be at a slight angle as that prevents the springs from flipping around to the other side of the equalizer over uneven terrain. I attached a picture that shows what the angle is typically like.

  • Selecting Replacement Shackle Straps for 30-Foot Toy Hauler Trailer
    Shackle straps are the most wear-prone part of a trailer suspension since they both carry weight and receive constant friction from the motion of the suspension. Shackle straps do not carry specific weight capacities, unlike the leaf springs they suspend. To select replacements all you need to do is match their length. Shackle straps are available in three lengths, 3-1/8-inch (single axle systems), 2-5/8-inch (tandem and triple axle trailers) and 2-1/4-inch, the most common length for...

  • Can 3-1/2" Shackles Replace 3-1/4" Shackles On Boat Trailer?
    Since your hangers are the same size you will just want to match the new shackles to your original shackles as that is how the suspension was setup from the manufacturer. With that said since there is only a 1/4" difference between the original3-1/4" shackles and the new 3-1/2" shackles like the # TRSL350 you purchased you won't have any issues. I included a video of the # TRSL350 for you to take a look at.

  • How to Find Correct Replacement Shackle Straps for Trailer
    In regards to measuring shackle straps, you don't need to remove them to measure accurately. If they are still installed on the trailer simply measure from the center of each bolt head, the two most common are 2-1/4" part # TRSL225 and 3-1/8" part # TRSL313. It looks like you have the smaller 2-1/4" but you really ought to just measure yourself first.

  • Can 2-1/4 Inch Long Shackle Straps be Used in Place of 2 Inch Long Shackle Straps on a Trailer
    The only way to know for sure if the 1/4 inch longer shackle straps, # TRSL225 (compared to the 2 inch long # TRSL200) will be a problem is to install them. The longer straps will likely mean they will be at a steeper angle once installed and that could affect the travel of the suspension. I do recommend not chancing it and go ahead and get the correct shackle straps # TRSL200.

  • Will Trailer Shackle Straps Rust
    The shackles like the # TRSL225 are bare steel. With enough contact with moisture they will begin to show signs of surface rust. Especially on a boat trailer that backed into saltwater.

  • Parts Needed To Convert Boat Trailer From Slipper Spring To Leaf Springs
    Since you are converting your trailer from slipper springs to leaf springs I have linked one of our help articles below that will be able to help you with the conversion. A single axle trailer will typically use a 3-1/8" Long Shackle Strap # TRSL313. I'm not sure that you will be able to utilize your existing rear hangers as with a slipper spring the spring sits inside of the hanger. When you bolt straps to the outside of that hanger the hangers will then be to wide to fit properly on...

  • Why Are Shackle Straps Hitting Frame When Re-Building Trailer Suspension
    The problem seems to be mostly that your shackle straps are hitting the frame, and the reason for this is almost certainly because the 3-1/8" Shackle Strap # TRSL313 you are using are too long. The other possibility was the hangers being too short but that is unlikely considering the lengths you gave. What I recommend is trying out the 2-5/8" shackle straps from the the # APT8 kit you have, as those are the typical length for a tandem axle trailer, while 2-1/4" straps such as # TRSL225...

  • Replacement 6 inch Equalizers and 2-1/4 inch Shackle Straps for Trailer Suspension
    When looking at equalizers for your trailer's suspension, anything at or over an inch in difference will most likely cause some issues with the overall suspension, especially if nothing else is being replaced. To replace your original equalizers, I recommend using the TruRyde Triangular Equalizer # TREQ310. This measures 6-1/16 inches in length and 4 inches in height. I have included a short demonstration video on this product for you to check out. I also recommend sticking with the...

    In order to determine if the Never Fail Triple Axle Suspension Upgrade Hardware Kit part # LC281288 will work on your 2004 Thor Vortex 385 5th Wheel Trailer you will need to confirm a few things. For starters, the bushings and bolts are designed for 1-3/4" wide double eye leaf springs that use a 9/16" bolt so you must make sure this is what you have. Then, the shackle straps included with this kit are 3-1/8" long so that will need to match what you have as well. This is the most common...

  • Why do Some Trailer Suspension Kits Have Longer Equalizer Hangers
    The reality is that not every manufacturer makes their suspension kits to the same standard sizes. Some use taller hangers with wider equalizers and some might use a taller equalizer with a shorter center hanger. It really just comes down to the preference of the manufacturer and what gives them the ride height and distance between tires that works the best for them. Also the fact that some trailer leaf springs happen to be longer or shorter plays into what is best solution as well. Ideally...

  • What Should Hanger Spacing be If Trailer Leaf Spring is 25-1/4 inches Long
    If the shackles you have now are still good you can reuse them but you would want to use a hanger spacing of right at 25 inches since your leaf springs are 25-1/4 inch. For replacement shackle straps you could use the part # TRSL225 for a 2-1/4 inch long shackle.

  • Are Longer Shackle Straps Needed with Lippert Road Armor Equalizer
    You'll be find with the same shackle length you're currently using, as the height difference is only a 1/4 inch. At the time you replace the equalizer, I'd also recommend replacing the shackle links, as they can see a lot of wear. The # TRSL225 2-1/4 inch shackle links would work great for you.

  • Replacement Shackle Strap Recommendation that is 3-1/2 inches Long
    Your question came in blank, but based on the picture you submitted it looks like you are in need a replacement shackle strap that is 3-1/2 inches in length. For that you would want the Shackle Strap # TRSL225. This strap is 3-1/2 inches long like what you have pictured with the hole measurements 2-1/4 inches on center. For a new shackle bolt you would want the Shackle Bolt part # 166081.

    We don't have an exact kit with the components needed but we do have the parts individually like with the part # TRSL225 for the shackles and then for the bolts # 166081 which includes the nuts as well. You'd need 8 bolts and then 14 shackles.

  • Replacing Shackle Straps After Switching To A Taller Equalizer
    Hi Mike, With the height of your equalizer increasing an inch you might need to switch to 3-1/8" shackle straps # TRSL313 to keep the leaf spring stack level but this isn't an exact science so your leaf springs could end up sitting too close to the equalizer and will bind up. Your suspension should form a 'W' shape with the equalizer and shackle straps for proper suspension travel. Too far in or out with your shackles will cause binding or will flip the axles down on the equalizer. Because...

  • Replacement Shackle Strap Recommendation For Single Trailer Axle Suspension
    The shorter shackle straps that measure 2-5/8 inches long like part # 115052GALV are typically used on dual or triple axle systems. A shackle strap that measures 2-1/4 inches long like part # TRSL225 are usually found in a dual-axle kit. I have attached a photo of a shackle strap that shows where you should measure to make sure you get the correct length. Unless you are changing the springs, or other parts of your trailer suspension I would recommend using the same length strap when replacing,...

    The prices are a reflection of factors such as demand, availability, cost, and several other variables. The nylon bushings are also the least cost effective component of the kit. Unfortunately, we do not offer the Never Fail Tandem Axle Suspension Upgrade Hardware Kit for Double Eye Springs part # LC281285 with 1-3/4" long bushings. If you have 1-3/4" wide leaf springs then you will want to piece your own kit together with the Never Fail Bushings part # LC279685, Shackle Bolt with Locknut...

  • Recommended U Bolt Kit and Shackles for 3500-lbs Axle
    For a 3500-lb axle, it's most likely a 2-3/8" diameter so you can use the U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles - 5-1/2" Long U-Bolts # APUBR-1. If this is a boat trailer or utility trailer that might be sitting outside a lot you may want to consider upgrading to the CE Smith U-Bolt Kit # CE23002 since they're zinc plated and will help fight off corrosion a bit better. For shackles, the most popular size shackle is 2-1/4" like the part # TRSL225, but you'll want to measure...

  • Availability of Suspension Kit with 7-3/4 Inch Equalizers
    We do have 7-3/4 inch equalizers with part # TREQE34, however it is not available in a kit like the Suspension Kit # AP233 that you referenced. Since the additional components included in the kit are correct for your application, you can simply obtain the kit but add the 7-3/4 inch Equalizers # TREQE34. Otherwise, you can piece together what you are needing with # TREQE34, the 2-1/4 inch Shackle Strap # TRSL225, and the Shackle Bolt # 166081.

  • Replacement 2-1/4" Shackle Strap Recommendation
    For your application I recommend checking out the Shackle Strap # TRSL225 which is 2-1/4" apart for the bolt holes, has an overall length of 3-1/2" and a 1-1/4" width like what you're looking for. We don't carry the TPU5212 kit but from what I'm seeing it looks like a whole kit so for a whole replacement kit I recommend the MORryde Suspension Upgrade Kit # MR58ZR which comes with bolts, shackles, and bushings for a tandem axle trailer.

  • Raising Trailer Suspension To Clear Rear Leaf Spring From Hitting The Crossmember
    It appears you may have installed shackle straps which are longer than what you may have had. It appears your straps are either 3-1/8" # TRSL313 or 3-1/2" # TRSL350 and you likely only need a 2-1/4" # TRSL225. This would move the mounting point closer to the axle and raise the trailer approximately 1/2". To get enough height to clear your crossmember you will likely need the Lift Kit # RR23QX. This will allow you to raise the suspension either 1-1/4" or 2-1/4" to clear your rear crossmember. On...
