That is a really good price for sure. Can't go wrong there. All the labour is done on the build for you so you just have to swap it in. Only a Couple hours work if you are good with a wrench. Add in a few hundred for the matching rear gear set and you are all done for under 4K.

I put an Artec truss on my Ultimate 44. It was a Rubicon D44 truss. Before you do truss it I would strongly recommend replacing your upper control arm bushings with Currie's aftermarket ones. I did not and will have to have some work done to replace them when the time comes.

Do you remember which Artec truss you got?
I have the UD44 in my garage.
I returned the G2 truss I bought that was designed for the JK Rubi44. It was so far off and was not worth modifying, the UD44's 1/4" thick bracketry is MUCH different than the stock brackets!
What did you need to do to the truss you installed? And what control arm bushings(axle side) did you install? I asked Synergy if they had replacements for them and - NO ANSWER..... so?
