To the OP,
@mrblaine has stock type used knuckles, or he did. If you ask, you can purchase a set. I did, and soaked in EvapoRust and sprayed with Krylon semi flat. They look better than factory.
I put a Currie steering and Trac Bar and my 4” lift on 35’s runs 75-80 all day on the highway and bumps, and no issues.
My suggestion, don’t go a step further, it’s never too late to make a good decision.
Putting the knuckles on was actually very, very easy. One of the easier jobs I‘be done on my TJ. Biggest suggestion, when you put the axle back in, use a bar to wedge it up some so you don’t push the inner seal. I may have over thoguht it, but didn’t want to cause a problem there ha.
