Video Transcript for etrailer Shackle Strap Review

Hello neighbors, it's Brad here at etrailer, and today we're taking a look at replacement shackle straps for your trailer suspension. Most times our trailers are stored outside and they're exposed to a lot of elements. So just like any metal, it can corrode over time and you can see here's our old shackle strap. It has seen better days, and sometimes your holes can actually begin to oblong over time as the suspension moves. And unfortunately, once it starts to do that, it can get worse over time. So replacing something that connects all your suspension, these are gonna be a strong point to have your lease springs go to your equalizer.

So making sure that these are actually structurally strong are gonna make sure that your suspension is gonna be working properly and safely. So these straps have a diameter hole for the bolt of nine sixteenths. And you're gonna want to look at your old shackle straps to make sure that these are a direct replacement. And you're gonna measure the length by going from the center of the hole to the center of the hole. And these ones are gonna be three and 1/8th of an inch.

These are going to be steel construction, so they're gonna be nice and sturdy. And also when replacing anything on your suspension, this is just gonna kind of give it a fresh look. You know, if you're replacing your equalizer and you have rusty shackle straps, that doesn't really aesthetically look great, so this is gonna give it a fresh look and also be structurally strong. Now these are sold individually. So if you are replacing your tandem axle equalizer, you're gonna wanna pick up four of them.

And that was a look at replacement shackle straps for your trailer suspension..

I replaced the equalizers, shackles, bushings, bolts, and nuts on an old trailer. Everything fit properly without modification. Product quality was excellent.

No problems to date. A coat of primer keeps the corrosion under control.


Perfect fit.


Nice pieces, I did have to clean up the burs around the edges


Great straps, fit as expected. After one year, they are holding up great.


Not much to say it's a shackle strap, I ordered 4 and they are as described and shipping was right on, I did however redrill them for 2" centers, I'm happy and wont hesitate to order from etrailer in the future.


Was suppose to be delivered on Aug 2, then it said Aug 4, today is the 4th and still no part and says Aug 7th now. Thanks to the poor communication and shipping time we have to push back our vacation


Better quality than OEM.


Quick delivery and exactly what i ordered. Thank you.


I am completely satisfied with service and the product that I purchased from The measurements and specifications on the web site were complete and accurate. Shipping was prompt and the parts were packed more carefully than anything that I have purchased online. Installation of my replacement leaf springs went seamlessly which I really appreciated as I had to leave my broken trailer at my hunt camp and had limited tools to do the repair.

I can't recommend highly enough. They are now my first choice in trailer parts.


Perfect fit for my 5th wheel suspension rebuild. Needed to raise trailer height and was suggested in the Correct Track lift system I purchased from Etrailer.


the product arrived quickly and new as promised. I was so impressed with the customer service personal. I needed help with size the associate I spoke with was so knowledgeable and helpful. I would recommend this company to anyone that is looking for trailer parts. Or any other product they may carry.

Cindy C.


wonderful as it should


Using has been a great experience. They have a huge selection of trailer parts and make it very easy to find the right parts. The packaging seems to have gotten alot better. Very sturdy box. It arrived within a few days from ordering which was a huge plus. I was able to get the job done sooner than planned. That kind of experience will keep me loyal to etrailer for any future trailer parts needs. Thanks guys and gals. Keep up the great work. As far as the parts, eveything was heavier duty than factory. Since I measured the old parts I was able to find the exact replacements for those parts. The job went so smoothly without any issues. These springs raised the trailer height without any load on the axles 1.5 inches. It was definitely time for new springs and hardware. Im kind of glad the one spring broke.


This is a multiple product review. The long bracket are good. The shorter brackets are of the same good quality. The issue is using the short brackets with the shackles. The shorter brackets could be narrower so the shackle line up better with spring and other longer bracket. We used washers to make it align better. The greasing bolts are good, but could be longer. so we could only use 2 of the 6 and had to use normal grade 8 bolts.


I was so happy to be able to order the exact replacement shackle straps for my RV suspension system. This monster wasn't moving again until the repair was made.

etrailer offered my replacement strap at a great price with fast delivery. Let's not forget excellent customer service, helpful videos and detailed product descriptions to ensure you get the right part the first time. Thank you etrailer staff for your excellent customer care. I'll be back when the need arises.



Loved the personal service and the help. I tried a few other sources before going online to order from etrailer. One place I tried was an online tool dealer, and their online site was a mess without help and so was a retail location. etrailer, was quick to find me exactly what I needed and got me fixed up in just a few minutes. From now on all my trailer needs will be fulfilled from etrailer!!!


I have bought several products from etrailer. Trailer fenders, spare tire brackets, tongue jack and retractable stern straps. I've ordered all my parts at different times and all of them have shipped and received to me in a short time. I will be ordering more parts from them on my next trailer project


The non threaded (solid) part was slightly longer than my original bolt. Bolt length is correct.
But I was able to make it work.


Great products for a good price and fantastic service. I will be using etrailer again.
I broke one spring on my tandem axle trailer. After a little internet search I found etrailer. I decided to change all springs(upgraded to p4)shackles,equalizers,n bolts) total price around $200.00 about 40 percent cheaper than a local trailer repair shop..I ordered it early on a Tuesday and I got the order on Wednesday. Changed out parts on Thursday and back on the road on Friday. Great company to deal with!!


Worked like they are supposed to. Held on by the bolts I purchased and leaf spring. It fixed what was broken.


Perfect and on time


I had a trailer spring break this summer on the way home from a 2,700 mile trip. Our small luggage trailer just couldn’t take anymore rough roads. One of the springs broke through the centering bolt. The website and Tammie P. came through with replacement springs and accessories. Thank you Tammie P. And!


These shackles installed easily and were the exact same dimensions as the ones I replaced. The shackles are solid and appear to be sturdier than the ones I replaced. Ordering with etrailer was easy as they provided all the dimensions needed to order the correct shackles. Delivery was fast as well.


I fabricate roll-out boat docks. I also fabricate light weight hinged shore ramps to make the transition from dock to shore. We weld 2 shackles at the end of a dock and the end of a ramp. We secure the ramp shackle to the dock shackle with a straight clevis pin and cotter creating a simple hinge effect. I like buying them in bulk vs a retailer that sells them in 2 paks and etrailer provides a good product at a fair price.


I ordered numerous trailer suspension parts. I really appreciated the bideo explanation of the parts as i have not worked on a trailer before and had to match them up w what i had. Ordered on sunday and arrived that friday. Good quality n great price. Will definite go to etrailer in the future!


Ordered these shackle links by far cheaper than anywhere else i could find them.i installed them very easily.they seem to b a solid product.most importantly to me is etrailers business ethic.they had me my parts days before the delivery date.they sent them immediatly after ordering them.whats most impressive is it was a 6.00 dollar them its just as important as a 600.00 order.etrailer is the place to for all your trailer needs trust me.its nice to feel appreciated no matter what your order is.etrailer is my 1st stop shop

  • Replacement 3,500 lb Leaf Springs & 7-3/4 Inch Wide Equalizer
    Thanks for all that info and we can get you exactly what you are needing. Since you have a 2-3/8" axle that would be a 3,500 lb axle, so you want leaf springs rated for that weight. The concern with springs that exceed the rating of your axle is that they will give you a very stiff, rigid ride, so you want to stay with the correctly rated springs. I'll go ahead and list out the parts you need, with a couple notes. First is that leaf springs elongate slightly over time, which is why the...

  • 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...

  • Can I Use 1/2" Longer Shackle Straps for My Trailer Suspension
    If the shackle straps are within a 1/2" of what you normally had, say the 2-5/8" # 115052 to 3-1/8" # TRSL313, you should be okay to install them. Just make sure that all of your shackle straps match though. If you are using the longer straps only for a section of your suspension setup then that will cause issues for your trailer.

  • Replacement 7,000 lb Leaf Spring & Mounting Hardware
    The 7,000 lb double-eye leaf spring we have that is closest to 26" is the 24-7/8" long 6-Leaf Double-Eye Spring for 7,000-lb Trailer Axles # e64SR. Assuming yours have flattened a good amount (which will definitely be true if the trailer is older), these will work out as a good replacement. You mentioned hardware, and I'm assuming you were referring to U-bolts, shackle bolts and straps. You'll need to measure your shackle straps but you can use the following: - U-Bolt Kit # APUBR-9 -...

  • Troubleshooting Lower Suspension Height On a 371 Fuzion 5TH Wheel Toy Hauler With MORryde CRE3000
    It is normal for the rubber to push out of your MORryde Shock Absorbing Suspension Equalizers # MR27ZR the way it is. The main issue I see is your Shackle Strap # TRSL313 is wearing out. I can see a bit of the hole on the top left strap which means the holes in the strap are being elongated. I recommend replacing these immediately with one of the following kits.

    Finding replacement leaf springs for your 1967 Aristocrat camper will require some more information. You will need your axle capacity, current leaf spring length, and the shackle length. If you don't know your axle capacity, try checking the axle tag to see if it is listed. For your leaf spring measurement, we are measuring from spring eye to spring eye. For the shackles measure center hole to center hole. For example, if you have a 3,500 lb axle with a 27" leaf spring measurement you...

    Although we do have 1/2" replacement bolts, there are no kits that include them. However, we can piece everything together. For a 1/2" bolt we have the # ABS74FR and for a 9/16" the # 9163B. Assuming an 11/16" outer diameter you can use the # TRBU11506 for a nylon bushing with a 1/2" inner diameter and # 721590 for 9/16" ID. You will need to make sure your bushings match the outer diameter. You will also need to measure your shackles to get the right shackle length. This measurement...

  • Replacement Leaf Springs, Shackles and Equalizers for 2012 Koala 21CS
    For a replacement leaf spring the part # e84SR would work great as this is a 2,000 lb axle leaf spring with exact dimension you have of 2-3/8 inches. For replacement shackles we have the part # TRSL313 which is the size you need of 3-1/8 inches. For wet bolts you'd want the part # 126B2 and then for cushioned equalizers you could use the part # LC279687.

  • Leaf Spring Options About 25 Inches in Length For 6,000 lb Axle
    You said "about" 25 inches in length so I'll give you a couple options for what might work depending on the exact length you have, and if you want to go to a higher-rated, 7k leaf spring. Also, you'll want your replacement springs to be a bit shorter because leaf springs stretch over time. If you happen to have leaf springs a bit longer than 25 inches (say 25-1/2 inches) you can use the 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/4" Long # e78SR.

  • Limited Tire Clearance with Stock Tire Size on a 2006 Forest River Cherokee 27Q
    We recommend having a minimum of 3" between the top of the tire and bottom of the fender in order to allow for proper suspension travel. However, based on the photo you sent I believe you need new leaf springs as the ones you have appear to be almost completely flat. This has then compromised your tire clearance. The flattened leaf springs could either be a result of overloading the trailer or just general wear. In order to replace them you would need to know your axle capacity and the...

    The # SP-210275 you were looking at is for a 3500lb axle and is 27" long measured from center of spring eye to center of spring eye. This is the correct spring for your trailer based on the measurements you provided. The next shortest spring would be 2" shorter which would be much too short. For replacement equalizers we have the # TREQR89 which is 8" long and has a center hole of 9/16", or the # TREQR83 which is 9" long and has a 3/4" center hole. For replacement hardware you can use...

    Yes, the Dexter E-Z Flex Suspension Kit # K71-652-00 will work on your 2004 DHM Tandem Axle Boat Trailer. The Equalizer is designed to replace equalizers with a 5-1/4" to 6-1/4" bolt hole separation. This may raise your suspension up to 1" as you have the flat equalizer rather than a triangular equalizer.

  • 2-1/2 Inch Shackle Straps Are Flipping After Replacing Leaf Springs
    Shackle straps can actually flip if they're too short as opposed to being too long, so it makes sense because you mentioned you put on shorter, 2-1/2" shackle straps. Also, if the leaf springs you replaced are shorter than what you had ( leaf springs elongate over time so you likely got ones shorter than what you replaced, as is common), straps can also flip. I recommend going with longer shackle straps, either the Shackle Strap - 2-3/4" Long # TRSL275 or Shackle Strap - 3-1/8" Long # TRSL313.

It's pretty easy though, as you'll just have to measure your current leaf springs from center-to-center of the spring eyes. Leaf springs also flatten a bit over time, so you should go with ones that measure a bit shorter than what you currently have. For example, if your leaf springs measured 22-3/4 inches...

The difference in the kits are in the rear hangers and the shackle straps. The Redline Single-Axle Trailer Hanger Kit, part # APS1, uses the Redline Rear Hanger, part # 30-20, which uses a steel bushing and is .91 inches tall.

    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.

    When it comes to shackle straps on a trailer suspension it really boils down to what looks correct. Since leaf springs and equalizers can be switched out (especially on older trailers), longer or shorter shackle straps can be used to help make sure everything is lined up correctly (see attached photo). As long as your suspension looks like that photo then it is perfectly fine to use 2-1/2" shackle straps like the part # 115052 which is 2-5/8" long. If your suspension doesn't look like...
