Hey so i bought tien tech H springs.

I replaced my front lower control arms with some unnamed ebay brand. They work fine just a pain to put in. The only flaw is their ball joints suck so i need to replace them. These are the arms i have

I was wondering what kind of ball joints would fit it and if i need the boot/sleeve thing too.

Also i plan to buy the shock absorber bushing kit but i click the kyb option and it doesnt tell me what it comes with. I would rather not waste money if i dont have to. I feel like for 300$, if i hit the kyb shock option they just remove some of the products and charge me the same 300$. heres that kit.

Also wondering anything else i may need when changing my shocks and springs.

 

with aftermarket it is really hard to tell what ball joints will fit. My best guess would be to take it to a competent shop that does alignments, they will have a varied stock of ball joints on hand and the tools to install / remove them, with a little customer service I am sure a local shop could sort that out.
