Rear lower control arm bolt size help.

[bkac]

Does anyone know the size and spec of the rear lower control arm bolts on a JK? I know its a 21mm socket but I need the actual bolt size. I need to get new ones 1/2 longer. Thanks in advance.

Forgot to add, I'm looking for the axle side rear lower.
I read somewhere maybe 14x1.25x100 or a 9/16x4.5. Just wanting to confirm.

14x1.25x100 in a 10.9 sounds about right to me.

Awesome! Thanks Eddie

I might actually have them and if not I go right past a place, Parkrose Hardwarea, everyday that will have them, in fact if your going to Ikea on Friday, you will be right by the place as well. I will check to see what I have when I get home and I'll let you know.

I need to get 2 that are 1/2 longer. I'm trying to plan ahead.

My brackets on my new axles are quarter inch thick and when you add the Rockstar skids to them they don't catch but one thread. Yeah I was getting ready to research it again cuz I went to the store and I could not find 1.25 in a 14mm. Only 1.50 and 2.00. thanx

Did you find them 4-1/2" long, usually only come in 100mm or 4" most places

Maybe a 9/16 fine thread grade 8?

9/16 should be easy to find, i would try too use the 14mm though as the 9/16 is .040 smaller and allows for slop

I might have a plan B to use the factory bolts if I can't find them.

I hope you are taking detailed notes of all the stuff you had to figure out with these axles. I think others would find it helpful. Just sayin.

I am. And I want to give an honest opinion of my experience. I have both positive and negative thoughts. But at this point in still glad a made this decision. More to come I promise.
