rc changed all of their control arms about a year or so ago so he maybe referring to the old jks style arms . Rc arms are now using the jonny joint style joint at one end and on theur website they say they are rebuildable .
Ome are very good in quility but rc coil springs are now all progressive.
ya, I saw they are rebuildable. What kinda life expectancy (in kms) should one expect to get out of a jonny joint? It is very nice it is rebuildable.
From what I have read, RC have really increased the quality of the products in the last couple years. I understand OME is the benchmark, but from what I have read, the kit I linked above has received excellent reviews and the ride is decent. The 2.5" lift seems to lose 0.5" as the springs settle/sag and the kit flexes a ton from what I would expect from 2.5" lift.
When going with the adjustable control arms, will that help mitigate vibes from your driveline angles? I would think it would, as you can "correct" the pinion angles a lot with the adjustable uppers. It would be exceptional if it would eliminate the potential need to use an MML or a xfer case drop and SYE, however it seems "every jeep is different" and there is not a set in stone rule..
