Alot of people are going crossover, seems to be the more hardcore dedicated wheelres. Lots dont like highsteer, because it gets in the way of things. You can do nrmal crossover with low steer, it just places the tie rod belowthe leaf spring.
J arms are the weak point of stock sa steering. They are not made to work at lifted angles, you can mod em a bit, but in the end, you have modded stock steering.
