These work great when paired with metal bushings. The splines may require a press to fully seat them. But now I can lube my suspension. 🤗

The quality is VERY poor. The knurls are at an angle so all they will do is make your shackle hole larger instead of stopping the rotation of the bolt. The locknuts are not actually lock nuts, they have no locking feature. The threads are not 7/16. The hex on the bolt and the hex on the nuts are of an unknown size.... they are not metric and they are not standard.... WTF. I brought them to my local trailer store and they laughed.

I cranked these wet belts up to help get the alignment of the trailer axle springs. Don't do that or you will be buying another set just like me. They strip out way too easy. I like the ability to grease the shackles on the trailer but the bolt doesn't have enough tensile strength to help with the alignment. Make it perfect and then tighten the bolts only to 40lbs of torque. No more.

Bolts for trailer springs worked great for the price. No running around to find parts.

Fit was nice. You do have to be cautious when installing them to not pull the threads. Read previous reviews that said the same thing so when installing them i watched very closely but they work great and made a very nice improvement to my car trailer.

These are not high quality bolts and nuts. The threads strip with very little force during tightening.

As the factory trailer parts are simple plastic bushings (and replacements are the same now) these are a must have for the wear points on the suspension of any trailer. My only complaint is they need washers as they are a bit longer than the standard spring width, so I knocked a star off since there isnt a mention of that. But I will for sure be purchasing again.
