Features to know about

Restores Solid Suspension Mounts: 9/16" Diameter Steel Bolt

When suspension bolts wear out, the whole setup can start to shift and creak. This 9/16" diameter bolt gives your double-eye leaf spring a secure mount at the front or rear hanger. It keeps the spring locked in place so your suspension tracks steady and performs the way it’s meant to.

Built to Resist Rust and Corrosion: Zinc Finish Holds Up Over Time

Road grime and moisture can eat away at untreated steel, but this bolt’s corrosion-resistant zinc finish keeps that from happening. It stays cleaner and smoother longer, protecting the connection points so you don’t have to worry about seizing or corrosion when it’s time for maintenance.

Simple, Reliable Setup: 3" Long for Straightforward Fit

Getting the right size bolt makes installation simple and alignment easy. At 3" long, this shackle bolt fits cleanly into standard suspension hangers. Just pair it with the proper locknut (sold separately) to finish the job and get your suspension bolted back together tight and true.

Consistent Strength for Everyday Towing

This TruRyde shackle bolt is built for the long haul. Whether you’re refreshing worn hardware or doing full suspension work, it gives you the solid connection and dependable performance your trailer needs every time it hits the road.

Worked great for installing leaf spring s.



by:

I am completely satisfied with service and the product that I purchased from etrailer.com. 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 etrailer.com highly enough. They are now my first choice in trailer parts.



by:

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.



by:

Worked perfect for my application.



by:

we plan on doing more business our trailer seem to be a hit see attached photo



by:

Great quality!



by:

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!



by:

New hardware makes the job so much easi er.



by:

Can't use until hubs arrive.



by:

It’s a bolt the quality is as you’d exp ect



by:

Worked should have got 3.5"



by:

Solid hardware.



by:

Its a bolt. Perfect fit for dexter 3500 lb axle on a load trail trailer with 1.75 inch wide leafs. The shoulder is the perfect length and it seems like decent quality.



by:

Bolts are as described. Did the job.



by:

Just what I needed, exactly match. Worked great!



by:

Bolts are missing SAE grade markings on head, so there is no indication that they are grade 5.



by:

Very happy part was easily order shipped and delivered in a few days



by:

Ideally, the shoulder of the bolts should be long enough to extend all the way through the spring and shackle so that the threads are not subject to load or moving parts. The treads are the weakest portion of any bolt and should only be exposed to tension, not sheer loads. This being trailer hardware, I guess that design factor is not a high priority. Just seems like it could be done right with just a smidge more effort or consideration. That said, the original bolts I removed had only a slightly longer shoulder and one-half the shackle was riding on threads and it held up for years, although it was worn considerably more in the threads.



by:

All parts fit my rebuild of new springs for my 1999 Bear trailer that my G3 Bassboat sat on for 26 yrs(used a lot for fishing on weekends)



by:

I wouldn’t buy my parts anywhere else but this order had 1 nut missing for my schackle bolts. Wanted trailer for job and stores were closed after 5PM. Box was sealed but no nut just made it a pain not to have trailer ready for work in the morning. Have your guys check a little better cause one little part can hold up a whole job. Thank You



by:

Same exact boats that were in it from the factory e-trailer is excellent about sending and shipping stuff to a person awesome company to deal with.

Just as expected. Would’ve been nice to also have the nuts that come with it but luckily I had a set at home that didn’t fit my last job.
