Ball Joint Question for Silverados

I have a 2000 silverado and i just got A-arms for it. 
What are some strong ball joints i should get? or should i run uni joints, and if so what are some good uni joints?
 
thanks alot

Moog or Power Performance for balljoints. I sell Jeebus Joints that you can use for that truck, they get a TON more travel than balljoins and are alot stronger 1" spherical bearing, teflon lined, stainless steel.  You cant use them with stock arms tho, you would need to either make custom control arms, or i could make them for ya.  Taylor
