Video Transcript for Review of TruRyde Trailer Leaf Spring Suspension - 3-1/2 Inch Long Shackle Strap - TRSL350

Hi everybody. Andy here with etrailer.com. Let's take a brief look at this shackle strap. Now, this three and a half inch long shackle strap is going to connect your double eye spring to your rear hangar of your single axle trailer or your equalizer on your multiaxial trailer. This connection, as you no doubt know, is going to allow movement to take place, ensuring an evenly distributed load between the axles. This is made of durable steel and shackle.

strap lengths are measured from the center of one bolt hole to the center of the other. So lining up my ruler here, as you can see on center, we're sitting right at three and a half inches, center to center, and that bolt hole diameter is 9 16ths of an inch. And if you're interested, the overall length of our strap is right at four and three quarters inches long, edge to edge, and then the overall width, we're sitting at one and a quarter inches. Well, that's gonna wrap up our real quick look today. I do hope that it was helpful for you.

Again, my name is Andy, thank you for joining me.

Only received 1. Parts are a 5, delivery options questionable.Can't delivery 10 pounds of metal in a paper mailer. Was tore open on the bottom. I run a mailing business and I can tell you its not that much more expensive to use a box.

Oh my goodness! I am sorry that it arrived missing 4 of these shackle straps. Customer Service will be in touch with you so we can send them out.



by:

My axle was maybe a 1/4" from the bottom of the trailer, so I replaced the 2" shackle with this 3-1/2" and so far so good.



by:

You sent me out side to measure middle od the eye to middle of the eye and I said 2 1/2in you send me a eye to eye of 3in.
I called you and left a message at 230 no return call.

Thanks for reaching back out, George! I am so sorry we messed up with the shackle straps. I made sure a customer team lead saw your review and they will be returning that call!



by:

The shackle and bolts fixed my problem .Original shackle had pointed or right angle corner and the trailer hung up.
The new shackle had a radius corner and didn't catch the frame.
Works great



by:

To me a shackle is made of 2 pieces. It is unusable with only 1 piece. $X.XX for half a shackle is overpriced, then they add insult to injury by charging $5 shipping.

Our manufacturers have typically sold the shackle straps as single straps unless they are part of a specialized kit. I was not sure what the second piece would be that you are looking for? Would it be a shackle bolt like part # 166081?



by:

very pleased with the springs i purchased,trailer towing is excellent.



by:

These are way overpriced. I found them elsewhere for $x.xx each.



by:

Everything was what was expected and the delivery was on time. I will always look to etrailer for my trailer parts. I built a trailer from scratch and it was etrailer that helped build it.



by:

Very good and reliable company. i searched for parts from many other suppliers and they all sent me the wrong parts. I found what i was looking for here and I got my package 2 days sooner than expected. will be ordering from here again!!



by:

Purchased replacement springs, equalizers, shackles and all the needed hardware to put it all together for my tandem axle boat trailer. While I was trying to figure out all the parts I needed on-line, I made a couple calls to etrailer's customer service and they were awesome! Parts arrived quickly and are exactly what I needed. I put together one of the spring / equalizer / spring set-ups and placed it on the trailer frame to confirm fit. Perfect! Looking forward to swapping all the parts out this weekend. And I'll be shopping with etrailer again soon to get a trailer hitch for my new Durango!
Thanks etrailer!



by:

It fit perfectly but it actually used it for a shackle on a hit rod I’m building . That car is a sebring 3000 mx with pinto leaf springs. Just so happens the shackle strap fit the shackle perfectly.when you build a hot rod you always open your mind to found what works. A trailer part on a car made sense .



by:

I can't say enough good things about the product or service. The order was shipped within a couple of hours of being placed and arrived 3 days early. This was important because I was stranded far from home. The sales help was great. The new leaf springs really improved how the trailer feels on the road. The picture is of my sheep wagon trailer at my hideaway in New Mexico after driving 1900 miles including highway speeds of 75 mph as well as crawling up jeep trails in four wheel low, the new springs took it all in stride.

No problems at all. Since I last commented I have taken it to California, numerous trips around California, to Idaho and back. I spend a lot of time on washboard gravel and dirt roads. Last week I had the tires replace and the springs looked perfect.



by:

I wish the shackle bolts came out as easy as ordering the parts!!!!
Jean at etrailer made it simple,answered all my questions and advised on some other items I would need to complete the job.
The parts arrived quick and everything was there. The shackle straps were heavy duty not light metal junk. The bolts and springs were also of the same quality.
Etrailer is trailers I highly recommend them you won't be disappointed.
Thanks again Jean.

So far so good never realized my old springs were so bad till I installed Etrailers parts.Thanks again, Paul S



by:

As usual, fast service with no mistakes. Correct parts shipped as ordered. Great communication with Alex



by:

good product



by:

These are very solid steel. But I didn't order them to use as spring shackles, but for steel straps such as for the bottom side of a U bolt. I also needed to replace a tongue jack mounting bracket but didn't want to buy an entire mounting kit (as suggested by an etrailer "expert") so I used this instead. You can see by the attached photo that they do a better job of mounting the tongue jack by not hanging down below the trailer tongue as the factory brackets do. But they do need to be painted--which is no problem since the zinc coated ones would also need paint eventually (unless you don't mind the rust). I bought several in various sizes for mounting stuff to my trailer tongues and for other projects.



by:

It was easy to order the parts, they came as predicted and it was an easy installation. Thanks for having the 3.5" shackles available when I needed them.

You are the first person or company that has asked how things worked out after use for some time. What an exceptional idea and likely good for understanding any real issues with the item. In this case the shackles gave me the extra 14 ground clearance that I needed and I have had no more problems with tires hitting the fender on off road driving. They were install on a small 10 home made enclosed trailer.



by:

The old and new. Got over 12 years from the first ones.



by:

Needed to raise my frame on a pontoon trailer for a little more tire to fender clearance. Going from a 2" shackle strap to this 3 1/2" worked perfect. Good quality and shipped fast.

Good value for the price. Started rusting within days of installation so take the time to rattle can if you hate rust like I do!

Great product, work like a champ. Excellent machining standards allowed for easy install. End result is more clearance in the wheel well.

Work great, hauled many heavy loads with no issues . Recommend



by:

Even with the product taking almost a month to arrive I gave Etrailer 5 stars... UPS lost my package and never admitted to it saying that it was USPS’s fault. Karen, at Etrailer, was very helpful with contacting UPS to try and figure out what happened, and ultimately re-shipping the items. After they arrived, they bolted directly to my existing enclosed trailer with no problem. Thanks again Karen!



by:

Etrailer.com has made the repair of my trailer very easy for me by supplying me with high quality parts at reasonable prices. They packaged the parts carefully and shipped quickly. I will no longer look anywhere else when I need trailer parts. This is a one stop and shop great place to do business. Thank You Etrailer, Dave



by:

This worked perfectly as I needed an additional inch of clearance between my fender and tire.

My fender was not able to be moved higher and I didn't want the height that an axle spring flip creates.

My old straps were just over 2" and this gave my exactly one inch of rise.



by:

Very happy with the service I received, will purchase again!

  • 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...

  • Replacement Equalizer, Shackles and Wet Bolts for 20 Foot Trailer with 7-3/4 Inch Wide Equalizer
    I have a solution for you, but the Dexter # K71-359-00 is not going to be a fit since the equalizer is only 5-3/4" wide. You could use the Suspension Kit for Tandem-Axle Trailers - 1-3/4" Wide Double Eye Springs - 3-1/8" Links # e99ZR, which has the correct size equalizer but does not come with wet bolts and the shackle are also slightly shorter than your 3-1/2" shackles; the shackle length won't be an issue since shackles can stretch over time but if you wanted a wet bolt kit it would...

  • Should 2-1/4 Shackle Straps with New Suspension Kit be Used Instead of 3-1/2 Current Straps
    The 1/4" shorter equalizer in the Dexter Heavy-Duty Suspension Kit # K71-359-00 will be just fine but you are correct that you don't want to use shorter shackle straps as well. You can either reuse your old ones if they are in good shape or use the 3-1/2" Shackle Strap # TRSL350 instead. It would be a good idea to just use new straps since you are changing out suspension parts anyways.

  • Dexter Axle Easy Flex Heavy Duty Rubber Suspension Equalizers With Longer Shackle Straps
    The E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle part # K71-652-00 does have 2-1/4" shackles so it would raise your suspension system up a bit if you use the shorter shackles. However, you can use the Dexter Axle Equalizers part # K71-654-00 and 3-1/2" Long shackle straps part # TRSL350 to make sure you are not raising your suspension.

  • Recommendation For Keeping Shackles From Flipping Up On Uneven Terrain
    Longer hangers will not prevent the shackles from flipping. If this has always happened or if the springs are new then they are too short. If it happens only when your trailer is empty then not enough weight/tension to keep shackles in place so they flip. This happens normally when the trailer is unloaded. If this is a new/recent occurrence then something-shackle straps, equalizer holes, etc- has worn out and needs to replaced. If it's a shackle issue, you will need to measure from...

  • Correct Positioning of Shackle Strap
    There is no set angle, but you want to leave enough room for the suspension to articulate. By looking at the photo, you will indeed need to move the rear hanger back a bit. The shackle strap be much closer to vertical, as shown in the diagram provided.

  • Can Trailer With Existing 3-1/2" Shackle Straps Use 2-5/16" Shackle Straps From Equalizer Kit
    Switching the shackle straps on your 2015 Big Tex 60CH would not be a good idea, especially since you would be using a significantly shorter size. In general, you want to keep the same length since swapping them out will change the suspension geometry and cause problems. Sometimes you need to use a longer shackle if you get a tall equalizer but I'm sure that doesn't apply here. Assuming you truly have 3-1/2" shackle straps you aren't going to find a kit with those since they aren't a...

  • Will Adding the Lippert Road Armor Raise My Trailer to an Unsafe Height
    We've seen a lot of our neighbors raise their trailer considerably more than 1/2" without adversely affecting handling on their trailers; many of them use spacer blocks or axle flip kits to gain as much as 4 to 4-1/2" of additional clearance. As long as your trailer tows level with your truck, I don't believe that extra 1/2" of height will have the negative effects you might expect. When it comes to adding the Lippert Road Armor # LC696740 to your 2021 Venture Sporttrek 327VIK, these are...

  • Switching from Standard Equalizers to Road Armor Kit and Recommended Shackles + Bushings
    You will be able to use the Road Armor Shock Absorbing Equalizers since they're fairly close in dimensions (6" wide x 3-1/4"). I recommend pairing these equalizers with the Never Fail Tandem Axle Suspension Kit # LC281285 which comes with 2 different lengths of shackle straps (3-1/2" and 4-3/8" bolt hole to bolt hole) to accommodate for the change in height, new bolts and bushings for your springs. One of the great things about this kit, aside from it being high quality and durable, is...

  • Which Equalizer Upgrade Kit Fits a Tandem Axle Trailer with 35 inch Axle Spacing
    Since your tandem axle trailer has an axle spacing of 35 inches the correct equalizer upgrade kit you'd want is the part # K71-449-00. The shackles of this kit are a little shorter at 2-1/4 inches but this kit would still fit and work well. The shackle angle would change slightly but it would not affect anything otherwise.

  • Availability of Trailer Suspension Shackles that are 3-1/2 inches Long
    We only have the # TRSL350 for a shackle that is 3-1/2 inches long from hole center to hole center. Typically these don't wear out as quickly as you described. Are you tightening the shackle bolts really tight which is causing added friction possibly? There is no specific torque rating for shackle bolts. You'll want to ensure that the bolts you use are long enough so that when installed you will have at least 2 threads protruding from the nut. Make sure that the bolt you're using has...

  • What to do if Trailer Shackles are Flipping
    Generally the issue when shackles flip when hauling empty is that they are too short. So I recommend measuring them from center hole to center hole and assuming they are less than 3 inches, replacing them with longer ones, the 3-1/8" Shackle Strap # TRSL313 or 3-1/2" Shackle Strap # TRSL350.

  • 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.

  • After Replacing Equalizers and Hangers on Triple Axle Trailer, Tires Are Rubbing
    The taller hangers are likely causing additional suspension travel which is causing the tires to rub. It is something that will need to be corrected. First, the new equalizers you installed are shorter than the originals. If you do not compensate for the shorter distance with either longer springs or shackle straps, that is likely the root cause of the problem. Also if you did not increase the hanger height equally for all hangers, then that will throw things off as well. You could keep...

  • Shackle Straps Are Flipping on Tandem Axle Trailer
    Shackle links can flip when the trailer is unloaded since there isn't enough weight to keep them in proper position, and while a new, shorter equalizer may help, the easiest thing to check is the shackle links. Shackles that are too short can cause them to flip, so the best thing to check first is the length of your shackles, and replace them with longer ones if possible. You'll want to measure from center to center of the bolt holes to check their length, and replace them with one of...

  • Recommended Shackle Straps and Bolts for 7K AL-KO Axles on Moritz Dump Trailer With 7-3/4 Equalizer
    For your shackle straps, I recommend the 3-1/2 inch # TRSL350 and for your bolts the Wet Equalizer Bolt with Locknut and Grease Zerk for Double-Eye Springs - 3-5/16" Long # 126B2. These bolts have the zerk fitting to allow you to add grease for better movement and less noise. If you prefer basic bolts, then I recommend # 166081.

  • 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...

    The longest shackle straps we offer are part # TRSL350, and those measure 3-1/2 inches hole center to hole center. For more clearance you may want to install longer hangers. Although these may be a lot more work because you would have to remove the old hangers and then weld new hangers in place, they may give you the length you need to move the wheels away from the fenders.

The height will be a little bit taller as it sits 5-5/8 which will be 1-1/8 inches taller than what you have. To compensate for this you can go with a taller shackle so that the spring gets carried at the same height.

  • Fender Placement Consideration When Upgrading Axles on Trailer
    Fender placement is going to depend on the specific application. There isn't a set amount you would need to move it when going to higher rated axles. You will need to consider the taller rims and tires you will be using plus the deflection of the suspension when it compresses. In most cases spring deflection is 1-1/2 inches when it is at capacity. You should note that when going to higher rated axles you don't necessarily raise the total capacity of the trailer. The capacity of a trailer...

    There are a couple different ways to raise the ride height of your trailer, but before we choose the best option for you, we will want to take a look at a few things. First, it sounds like you are not towing with your trailer level so you do not hit your ball mount on the driveway.
