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

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 738002

If you look closely, the bolt head is serrated; this area is thicker than the smooth diameter of the bolt, so you will have to hammer it into place. My trailer is older, so I had to take a round file to smooth out the eyeholes and then hammer in the bolt about a 1/4 inch so it sat flush. The plus is the serrations grab the eyehole of the steel so when you tighten the nut, the bolt won't spin. 728978

These are a must for a boat trailer that's put in salt water. They will last much longer than black iron style. 727555

Same review as on other parts that came together: I ordered several things from e-trailer, all of which were great quality. There was a problem though...I did order online and reversed house number by accident and order didn’t arrive as anticipated. That said, even though shipping was my goof, e-trailer (Natalie and George) contacted the shipper, ran it down, corrected my error, and I got my items the same day. Wow, talk about exceptional customer service. E-Trailer gets 5/5 stars from me. Could not ask for better service, and my parts...trailer springs too, were excellent. Thanks!!!!

The replacement trailer spring set was out of stock but Michelle watched for it with care and kept me informed. She let me know when it came in, shipped it quickly and made sure I had all the nuts and bolts needed to replace my broken springs. Have ordered from etrailer in the past and the quality and price can't be beat. 707991

Ask the Experts about this TruRyde Trailer Leaf Spring Suspension
- Recommended Shackle Bolt for 2,000 lb Utility Trailer Leaf Spring Suspension SystemThe 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. ...

- What Bolt Grade is the part # TRFA73Z916DLNZThe bolt part # TRFA73Z916DLNZ that you referenced is a Grade 5 bolt.
view full answer... - Gaps Between Shackle Bolt Heads and Shackles on Double-Eye Trailer SuspensionFor 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.
view full answer... - Is Lock Nut with Nylock Difficult to Thread Onto BoltNuts 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.
view full answer... - Recommended Shackle Bolt For Escort TrailerThe shackle bolt we offer that measures 3-1/2 inches is part # 166079. This is a 9/16 inch diameter bolt and includes the locknut. We do not offer a shackle bolt that measures 9/16 inch x 4 inches.
view full answer... - Troubleshooting Trailer Suspension Bolts Splines that Aren't SeatingHave you tried tapping the bolt in with a hammer? Hopefully not much force would be needed. Ideally you get the splines seated all the way but then you don't have to really torque the nuts down as the bolt needs to allow the suspension to move. You might open up the holes a bit more to allow the splines to fit through if they are being stubborn.

- Installing Lippert Equaflex Suspension And Never Fail Hardware To 5th Wheel Toy HaulerThe 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.

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...

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....

- Should Nuts and Bolts Be Replaced When Installing New Trailer EqualizersThe 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...
view full answer... - Availability of Tandem Axle Equalizer Kit Like # AP233 But With 6-1/8 Long Equalizer # TREQ356We do not offer a tandem axle trailer equalizer kit like # AP233 that includes 6-1/8-inch equalizer # TREQ356. However, you can order the individual parts equivalent to a kit. Shackle straps (2-1/4-inch) are part # TRSL225; Shackle Bolt with Locknut is part # TRFA73Z916DLNZ.
view full answer... - What Should the Bolt Diameter be on the Center Hanger to Use with the Curved Equalizer # TREQE34If 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.
view full answer... - Recommended Replacement Suspension Parts for 18 Foot Bass Buggy Pontoon Boat TrailerIf 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,...

- Are Other Parts Required When Replacing Trailer Equalizer With Equa-Flex Cushioned EqualizersI 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.

- What Is The Purpose Of Steel band On Leaf SpringsThe 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....

The overall thickness of the spring pack is 2-1/4 inches which might be thicker than what you current have and could affect the height of the trailer. For a U-bolt kit you would need the part # APUBR-8 which is for the 6k axles like you have. The equalizers you have now are Equa Flex Cushioned equalizers so for a replacement set...

- Piecing Together an E-Z Flex Equalizer System with 3 Inch Shackle StrapsDexter 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.

The Road Armor Shock Absorbing Kit part # LC696740 is a better option then the MORyde kit to help eliminate some of that movement because it provides about 3" more of suspension travel capability for a smoother ride. The cushioned Road Armor system will absorb the road shock to help eliminate the up and down movement you are experiencing. I have attached the dimensions of the equalizers...

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...
view full answer... - Will the Never Fail Bushings Work On a Grand Design MomentumThe Never Fail Bushings part # LC279684 will work with pretty much any trailer with double eye leaf springs. The double eye leaf springs must also be 1-3/4" wide but this is pretty much standard for double-eye leaf spring so as long as you have double eye leaf springs then you should be just fine. Please note, it will be a good idea to replace the eye bolts when you are switching out the bushing so for this you can use part # TRFA73Z916DLNZ.
view full answer... - Suspension Components For Tandem Axle TrailerWe do have tandem axle suspension kits with equalizers, but the three items you mentioned are not available in one kit. You can order # TREQE34, part # 115208GALV , and # TRFA73Z916DLNZ separately. You will just need to change the quantity you need in the shopping cart when ordering.
