Fact is any heim, hi-misalignment or not, needs to be sitting in the middle of it's range of motion for it to provide maximum droop & stuff. If you're already using up 1/2 of it's travel at ride height then it's gonna bind/break on droop.
With a crossover steering setup the pitman arm heim or tre is providing your droop when the passenger side wheel goes down, the heim at the passenger side steering arm is providing droop & stuff for the driver's side.
I dont care what anyone says, the ONLY way to make your heims sit in the middle of their travel at ride height with any kind of lift is to 'Z' bend the draglink. Sucks, but that's the facts.
A passenger side hi-steer arm will help give you back some of the travel as will a dropped pitman arm, but both have disadvantages too.
Depending on the heims you have, you may be able to get "heim adapters" that will fit inside the ball ends of the heim and use a smaller bolt, these are machined to use the full range of travel of the heim as opposed to a piece of tubing/spacer that may not "suck up" into the heim at max misalignment. There is an 1/4" difference between ball size & bolt size with "heim adapters", ie: 3/4 ball x 1/2 bolt. If you plan on running these adapters get 7/8 ball heims with 5/8 bolts.
Good luck.
