Control Arm Question

I was looking at these 2 lower control arms and wanted to get some opinions on these 2 kinds. Should I get either rubber bushings or poly bushings. I do mostly street driving with occasional offroading.

Most guys avoid poly for control arms.
If you have the $$ budget, look at a Johnny joint type such as savvy, or duroflex joint such as metalcloak. If not stuck to the rubber type factory bushing.

one of the BEST controls arms on the market for both on road and off road awesomeness are the JKS control arms. They use factory bushings to keep the on road ride great as well as they way they flex they do not bind in any way. they are also adjustable down to 1/16th of an inch.

I can think of two options that are superior and happen to be a better value as well.

I daily drive my Jeep and I am a fan of arms with the proven johnny joint ends. On rode performance is superb.

I am, as well but there's another great option now. Do you have any experience with it?

LOL, they came out a few months after I jumped the gun and ordered the Rokmens. From your review, I believe I would be happy with them as well .

for a cheaper price, race proven durability, and superior flex, why would anyone choose anything but JJ or duroflex?

you talk about on-road performance. have you ever been in a rig with JJ or Duros?

Curries are more expensive... and yes I have ridden with JJs and did not like the ride change.

FWIW, I've ridden in rigs with JJ/JJ and MC bushings. my rig has Clevite/JJ arms.

All ride very nicely, nothing harsh at all, and much better axle control than stock arms.

The benefit of the JJ or the MC bushing is they account for axle misalignment that occurs within the suspension cycle (the axles moves left and right respective to the frame during flex due to the track bar pushing/pulling it). The stock Clevite bushings do account for this only to a minor degree - but when you lift the Jeep and start running longer travel shocks, you're now operating outside the limits of the stock arms. Also, any arm that rotates along their long axis by constantly changing the arm length & cycling a threaded section is asking for problems, then add on using bushings that don't account for misalignment on both ends, and you can see it isn't a very good way to do things.

uppers are about the same price, jks lowers are about $75 more

there should be no noticeable NVH difference when going to a JJ or duro. and thats if the arms that were replaced were in great condition.

I just saw MC make aluminum double adjustables. I might have to go with these. Does anyone have these that can give us some reviews on them how they perform on road and offroading. Thanks!

there is a huge thread on the joints over on JF. the arms dont really mean much, its all in the joints. I'm rather confident that MC can make a quality arm with lh/rh threads
