I have a first production run 2018 Sport S unlimited. I added the Mopar lift in prep to put on 35’s, and accounting for the factory suspension settling it ended up yielding around 5” of actual lift. It’s since settled to a more reasonable 4” of total lift from the starting point. RE track bars were installed and aligned properly, along with a Fox 2.0 steering stab.
The jeep since new has always wanted to wander a bit on the highway, even stock. It’s more than just the vagueness on center with the steering (about 5° on center) which I will address with a Synergy sector shaft brace. Measuring castor after the lift I’m at 3.8°, which is the very front edge of tolerance. I’d like to be in the 6° range before I go to 35’s.
That said, I think I’ve decided on the MC LCA’s with the Duroflex joints. While the Jeep is used off road often, it rarely gets articulated near its limit where I go. Looking at MC’s website, it looks as though they recommend shortening the upper control arms over lengthening the lowers to achieve proper castor. I’d rather not draw the axle rearward if I don’t have to.
‘My questions:
Given my setup (Mopar lift, currently on 33’s going to 35’s) and what I do with it (fire trails with only mild articulation) would lengthening the LCA’s alone be satisfactory? End goal with going to 6° is to improve highway tracking.
While I prefer Johnny Joints, I do like the idea of the Duroflex joint. No need to grease, easily and inexpensively replaceable, while still providing a more stock-like amount of isolation. Has anyone had any long term issues with durability? Keeping in mind I rarely flex the Jeep out. The trails I use are so mild I don’t even disconnect. I just need ground clearance and sand floatation (hence the step up to 35x12.50’s).
And finally, I see that the MC LCA’s don’t have a provision to mount the front brake line brackets. Would it hurt anything to just remove the brackets andlet the lines dangle, or should I be finding another method to secure them?
