I respect Mike and all, but not everything he writes is correct. The average uni-ball actually has 35 degrees of travel. A stock Toyota balljoint, and a stock S10 balljoint both have about 29-30 degrees of travel. A power performance S10 balljoint has 33 degrees of travel. And the Chrysler balljoints I used on my truck get 32 degrees of travel. The Chrysler joints are $15 each about. Then you get the thread in bung for them which is like $12 and you build your arms off that.
I can get damn near just as much travel as Mikes truck can. I get 13" of useable travel, but I limited it to 10" with my shocks because it look sstupid any higher.
