A couple of things from earlier -
Ackerman angle has been corrected on the newest generation of hellfire knuckles, it looks pretty close for a 110 WB from what my eyeballs can tell.
I have both the slee and hellfire setups. Nothing wrong with slee, but the hellfire is not much more and you get a ton of benefits. Wider stud spacing, more studs, more mounting options, a much stronger and adjustable pin (no more shims), new trunion bearings and stronger knuckles. I am running the drag link over the top and tie rod under with a 9.5 diamond housing and offset TRE's on my lx470. had to notch the frame for drag link clearance, but it was worth it to keep the axle side of the panhard as high as possible.
The slee arms are not really high steer arms, they are only supposed to be run double shear and are best with the drag link mounted under the arm. For me, I already had a RHD arm laying around and just want to get the tie rod away from the radius arms, so they work. You end up with 7 studs total with the slee arm mounted double shear, but the vast majority of the stress is on the 3 studs of the upper arm. The best part about their design is that they are a machined fit, so the ABS bung acts like a dowel. Not sure how they will hold up, but I don't have any worries. I am also using ARP studs. By the time you factor in 14 of those and slee arms, you are within $100 of hellfires with the cool guy discount.
If hellfire knuckles were keyed, they would by far be the ultimate. Brian's setup is awesome, and I may have gone that route if it were available when I ordered my housing. Keyed arms take all of the torsional force off of the steering studs and put it directly into the knuckle. If any of you have run mini truck stuff, you probably know that pain...
