Khris, I gotta say, I'm pretty good with tools an building stuff, but your fan skills far exceed mine! And thats an understatement. Is there a shop here you can recommend for a custom kit? Bought kits have easily replaced(bought) parts in case of failure.
I know lug studs should be ok, just like glock pistols rarely fail, but I just don't trust them.
The thing is, with a well built custom kit there really shouldn't be anything that fails. Brackets like the ones ruffstuff or Artec Industries make are going to outlast your frame rails. The link arms can be built out of whatever type of insane material you want like say 2" x .375W or something absurd like that. Track bar I'd just go buy an existing one and really that only leaves the rod ends/bushings in the arms to wear out which are just generic run of the mill parts that can be found at Butch's speed shop or Nevada Offroad if you were in a pinch and needed some locally. If not you can mail order them cheaper actually.
As for shops around here, honestly I've only dealt with one and he's getting more and more away from the offroad stuff and working more with just general metal working. Also he's very SLOW. I mean VERY VERY VERY slow so I'm a little gun shy giving his recomendation these days cause of that. Prices are great, work is amazing, time is ummmmm, less then desired typically even for the patient people!
I do most of my work myself so I don't really have any experience with any of the local shops.
Adam's probably knows someone, backcountry probably does too. If the name woolworth or winward ever pops up, run away fast from either of those guys!
Other shops in town I know of but have no experience with is Dirt Freeks and also DERTCO. I don't know how much jeep experience either have though. Both are putting out great high speed rigs. DERTCO's builds are usually borderline artwork actually. I don't know what their pricing is like though.
Talk to Garza, he's got his jeep being custom built with a true 4 link in the rear and wishbone 3 link up front if I remember correctly. No clue what price range he's looking at but from the list of the build it's going to hands down make everyone on this forum drool!
