Most Popular 9/16 Inch Diameter for 2019 Volvo XC90

The wet bolts were just fine. But the "locking nuts" with the crimped edges were aweful. The 3 dimples each nut has were not useful. Many of the nuts I could use my fingers to spin them on the bolts. Never had locking pressure. I ended up going to local hardware store for much better locking nuts.

I used these "wet" bolts on my leaf spring change out. I ended up using 3 per equalizer since that seems to be the location of most of the movement during axle travel and a friends 5th wheel had 3 installed on the factory set up, so that is what I went with. I painted a yellow mark on the head of the bolt in reference to the grease hole in the shaft, so that I could install them in the direction of "least resistance" when greasing them later, after reading how some guys have to relieve pressure on their trailer in order to get the bolts to take grease. I used Mystik 6 grease mixed with anti seize when putting everything together, then gave them 2 shots of Mystik 6 after installation. (I chose Mystik 6 because we always had good results with that grease when I was in the aircraft industry and it doesn't was out.) I did notice that the grease zerks did allow grease to return out of the fitting which means the spring behind the ball isn't doing its job. That is why I rated them as "good". There are different ways to install these due to the knurled shoulder. If you have access to an impact gun you can just tighten them in with that. Pulls the knurl right in to the shackle. Overall I like the idea of having a suspension that can be greased.

I needed it quickly because on stripped on my trailer and we were getting ready to leave the state in our Wold Pup. I paid for the extra shipping and they got out and to me in 2 days. Thank you.

These are the exact bolts used by the manufacturer of my trailer. I had a spring break after 10yrs use, so am replacing the springs and all the bolts at the same time, thank you to etrailer for the springs (ordered earlier) and now the bolts/nuts, all arrived quickly and accurately, you are my first choice for all trailer parts for my 7 trailers, thank you and keep up the good work!

Worked and fit perfect. Thanks

Quick delivery and excellent customer service (with follow-up emails to ensure that everything was ok with the order). This replaced a broken bolt on a 1956 camper trailer, and it's a very close match to the original.

Had a leaf spring break on my off-road trailer in Mexico. Left it at a boat yard until I received the parts from trailer & returned to replace. Only took 2 hrs to replace both leafsprinhs, shackles, bolts etc. And we were back on the road.

Melissa T Provided excellent customer service. I Would recommend to everyone use etrailer.

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.

New bolts made replacement of springs easy
