On my crossover, I used identical right hand threaded TREs on the draglink. They are the same as the rh TRE on my Tie rod, so spares are easy to find. By using the TRE's on a draglink, they are stronger and tighter then the 2 year old DLE's I took off.
I'm not quite as hardcore as some guys here, but some one ton guys with like 40's and up have bent stock DLE's in a crossover setup.
I'm using an ORD arm and a superlift dropped pitman arm.
