Video Transcript for TruRyde Trailer Suspension TRFA73Z916DLNZ Review

Today we're going to review part number TRFA73Z916DLNZ. This is the TruRyde zinc shackle bolt with the lock nut for double-eye springs. This shackle bolt is a 9/16" diameter, and it is used to mount your double-eye leaf springs in your front hanger or your rear-suspension hanger. The lock nut is included. The shackle bolt and nut is a corrosion-resistant zinc finish. It is a 9/16" diameter, I mentioned, and the length of it, this is for 3" long.

So basically the way you would measure that is if you measure from under the head of the bolt to the very end of the bolt. And you can see there that it's 3". One other little item we need to mention to you is, this is a lock nut. It may look like, just by looking at it, a standard nut that attaches to the bolt, but this is what is called a distorted lock nut. By the distorted they mean that if you look at this side of the lug nut, it is actually oval shaped.

If you look at the bottom, it's actually normal round shape. What they do is they crimp the very top of this, and you can tell that by if you look at the sides you'll see crimp marks right here, and then 180 degrees crimp marks on the other side. So they basically crimp this and squeeze it a little bit to distort the top of the bolt, and that will give it it's locking feature. So when this lock nut is installed onto your shackle bolt, what you want to make sure is that these crimp marks right here that are at the top are facing to the outside. So in other words, make sure the crimp marks are facing to the outside.

And you'll start it, and it will start about one thread. It won't start a whole lot. It will seem like the threads are cross threaded or something. but just go ahead and start that way. Actually, what you'll need to do is once you install your lead spring in your suspension, and then you're going to put the nut on there, just start it like that.

Make sure your suspension is all lined up, everything's ready to go before you tighten this down. Now once it's all ready to go, go ahead and tighten this down, and as you tighten this down, it will lock onto this bolt when it gets to this distorted part. So that is very critical. If you try to do it with the crimp marks facing inwards, it just won't start because it's distorted and the threads will not start. So a little tip there is to just make sure those crimp marks, that you can see right here, are facing out. It'll start maybe one thread, not a whole lot, and then you'll be ready to install the shackle bolt. Hope that helps you, and that should do it for review on part number TRFA73Z917DLNZ.

These parts were for a 1977 Citation Travel trailer frame that someone had cut the springs off because the electric brake drums were to tight to roll and quite rusty so adjustment was not practical in the field.The springs and assembly pieces arrived promptly. The installation was completed in one hour. All parts fit exactly as they should. The goal is to make a storage trailer unit 8 X 18 feet. 293851

Wth rusted out leaf springs on my trailer but with zero experience replacing them, I contacted etrailer and Shawn was very helpful in selecting the right parts and taking me through the process. She was patient in terms of helping me take the right measurements and suggesting the bolts and pieces I needed to do the job right. Everything came well packaged and complete two days later. An hour after that the springs were in my trailer and now has a boat sitting on it. Thanks! 423135

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. 369867

I never saw locknuts like the ones that came with the bolts. They are only slightly dented on the exterior/last thread of the nut. Looks home made..lol . Bottom line if the bolt is just big enough to fit the lock nut most likely will not fair well. I punched the bolt threads as a assurance. 104580

I live 2 miles from the ocean in coastal SC. I have two work trailers and one, if not both are used every day. The salt water takes it's toll on trailer parts. This is the 2nd spring set I've purchased from etrailer. Both times I was very pleased with the ease of the web site, my contact with their customer service was excellent and all the parts arrive very quickly, fit exactly and were priced fairly. Good CS, good parts and good price, what more can you ask for. If I need trailer parts again I WILL come back to etrailer. 548090

I purchased these bolts and bushings to "tighten up" the suspension on a three rail Pacemaker motorcycle trailer I bought in 1974. Used a large welding clamp to press the bushings into the spring eyes, drilled the original shackle plates from a worn 1/2" hole to 9/16" and everything fit like new. Great service from etrailer. 491593

Do you have a question about this Trailer Leaf Spring Suspension?


  • Installing Lippert Equaflex Suspension And Never Fail Hardware To 5th Wheel Toy Hauler
  • The Equa-Flex Cushioned Equalizers w/ Never Fail Bushings - Double Eye Springs - Tandem Axle - 6K to 8K # LC279688 and Never Fail Tandem Axle Suspension Upgrade Hardware Kit for Double Eye Springs # LC281285 will give a nice upgrade to your 2014 Keystone Raptor MP300 Toy Hauler. The only hardware you need in addition is the equalizer bolt to your center hanger. For this you can use the Zinc Shackle Bolt with Locknut for Double-Eye Springs - 3" Long # TRFA73Z916DLNZ or standard bolt # 166081.

  • Do Suspension Bolts Need to be Replaced when Installing the Never Fail Bushings # LC279685
  • Since you have a 2017 Forest River Wildwood 28 DBUD the bolts used in your suspension should not need to be replaced with the part # LC281285. Unless for some reason your bolts are damaged and need to be replaced you should be good to use just the Never Fail Bushings # LC279685. Please note that Never Fail Bushings are meant to be used with standard bolts like part # TRFA73Z916DLNZ as grease will destroy them. You can use the bushings with wet bolts but only if you clean them and...

  • Recommended Shackle Bolt for 2,000 lb Utility Trailer Leaf Spring Suspension System
  • The Zinc Shackle Bolt with Locknut for Double-Eye Springs - 3" Long # TRFA73Z916DLNZ is a grade 5 bolt. Your setup as described is a standard setup for leaf spring hangers and double eye leaf springs. The # 166081 is made by the same manufacturer and is used more commonly than zinc plated for most factory applications. The cost difference comes down to supply and demand. The Dexter bolt # 007-003-01 is simply a different manufacturer that has a big name in the trailer axle market. ...

  • Will Road Armor Equalizer Replace Equa Flex Equalizer # LC279687
  • The Road Armor Shock Absorbing Equalizer Kit # LC696740 that you referenced is close enough dimensionally to the Equa-Flex equalizer # LC279687 that you have now so it will fit and work well. Bushing come with this already pre installed, for bolts you'd want the part # TRFA73Z916DLNZ but for shackles you'd need to let me know what length you have currently. I attached a link to a page that has all of the shackles we carry as well.

  • Never Fail Bushing Or Shock Installation On A Tandem Axle Trailer
  • The correct Never Fail Bushings for your trailer are part # LC279684. The Never Fail Bushings are not compatible with wet bolts kits therefore, you will need to use the Zinc Shackle Bolt with Locknut for Double-Eye Springs part # TRFA73Z916DLNZ. Even with the Never Fail Bushings and Upgraded Equalizers, you will still see an improvement in your trailers handling and stability if you add shocks. The shocks will allow for a much greater distance of suspension travel and smoother ride....

  • Piecing Together an E-Z Flex Equalizer System with 3 Inch Shackle Straps
  • Dexter Heavy Duty Suspension Upgrade Kit # K71-358-00 is exactly what you need though on a tandem axle you would need 2 sets. E-Z Flex System # K71-652-00 does not use wet bolts to hang the equalizer part. It has grease fittings on top for that so you can just use a regular bolt. So you would use # K71-654-00 for the equalizers by themselves, 2 of kit # K71-358-00, and either reuse the hanger bolts you have or use 2 of # TRFA73Z916DLNZ or a similar bolt.

Compare your measurements to those to see if we have a match. 3-Leaf Slipper Springs for 1,500 lb Trailer Axles, # SP-178275 3-Leaf Slipper Springs for 3,000 lb Trailer Axles, # SP-039275 Although...

  • Should Nuts and Bolts Be Replaced When Installing New Trailer Equalizers
  • The bolts would have the same thread pitch as the nuts. The reason why you could only get the nut tightened a few threads is because the nuts that are used are lock nuts. It is recommended to use new hardware, nuts and bolts like the Zinc Shackle Bolt with Locknut, part # TRFA73Z916DLNZ, when replacing the equalizers. You would need to measure your old hardware to determine which replacement bolts you will need. I have linked all the suspension bolts we have available and a video...

  • Recommended Replacement Suspension Parts for 18 Foot Bass Buggy Pontoon Boat Trailer
  • If the axle isn't bent from being overloaded (wear on outside of tire tread), then you're probably okay. If it's bent, you'd want to replace it. Since you don't know the axle capacity, we can make a pretty good guess if we know the bolt pattern of the wheel/hub as well as the inner and outer wheel bearing reference numbers. Knowing the axle capacity is important, so you can choose the proper replacement parts. We offer a few standard sized 2K and 3.5K axles. To recommend a replacement,...

  • What Should the Bolt Diameter be on the Center Hanger to Use with the Curved Equalizer # TREQE34
  • If by "perch" you mean center hanger, then you would want the center hole to have a 3/4" diameter like what you find on the hanger part # 115919. This will allow you to use the Shackle Bolt # TRFA73Z916DLNZ or Wet Equalizer Bolt # 126A1 with the Curved Equalizer # TREQE34 and keep the movement at a minimum.

  • Are Other Parts Required When Replacing Trailer Equalizer With Equa-Flex Cushioned Equalizers
  • I have attached a photo of the Equa-Flex Cushioned Equalizers, part # LC279688 you can check out. The dimensions are noted on the photo. As long as your axle is within the 6,000 to 8,000-lb capacity these will work for you. While you are changing out the equalizers you may want to consider new bolts and nuts. I recommend part # TRFA73Z916DLNZ. This is a Zinc shackle bolt with a locknut.

  • Gaps Between Shackle Bolt Heads and Shackles on Double-Eye Trailer Suspension
  • For a 9/16 inch shackle bolt such as # TRFA73Z916DLNZ you will want 65 to 95 foot pounds of torque. Provided that you are within that range you won't over-torque the nuts. A little bit of play is expected but large gaps could be taken up using washers. The spring eye does need to be able to move though so it can't be sandwiched between the shackles too tightly.

  • Axle Weight Capacities Compatible with Lippert Road Armor Shock Absorbing Equalizer Kit LC696740
  • The Lippert Road Armor Shock Absorbing Equalizer Kit # LC696740 is rated for use with two axles that each have a weight rating up to 8K so it will be fine to use with your two 5200-lb axles. The rubber cores in these equalizers will absorb much of the road shock and chucking that occurs with standard non-cushioned equalizers. If you need shackle bolts you can use # TRFA73Z916DLNZ for standard bolts/locknuts or part # 126B2 for a wet bolt that has a built-in grease zerk fitting for using...

  • Is Lock Nut with Nylock Difficult to Thread Onto Bolt
  • Nuts that have Nylock built into which is what prevents them from backing off over time. It's what makes them a "lock nut". The downside is they can be a bit difficult to thread on since it has to be super tight. You still might verify that the nuts is the correct size for the bolt and you aren't cross-threaded. If you remove the nut does the threads on the bolt looks damaged where the nut was? If so, it's not the right size or it's cross threaded.

  • What Is The Purpose Of Steel band On Leaf Springs
  • The leaf springs are normally installed with the band forward of the axle, but it is not something that has to be done that way. The steel band is called the rebound clip. Their main purpose is to help keep the main leaf from breaking on a rebound. When the weight of a vehicle or trailer is on the spring, all of the leaves work together to support the spring above them. If the wheel drops for any reason the total weight of the axle falls on the main leaf if there are no rebound clips....
