MC arms

Put a full set of MC arms in a month ago to replace my stock arms with 65K on them. They are way more solid then the stock but very happy with the lack of noise. Leaving for Moab in a month so it will be fun to compare with the old arms

I would rather not have the OE bushings. What is the reason for not mixing?

JJs are much harder to rotate so once it is turned the Duroflex would be under constant tension trying to recenter the JJ. With a Duroflex or an OE clevite rubber they both would return to center being its natural for them to do so and remove any uneeded tension on the joints

Nope I missed your sig. So obviously I must have also missed Duroflex joints with left hand threads?? I currently run the JJ front housing kit which if I recall also use 2" joints. As you mentioned probably not a good idea to run JJs and Duroflex on the same arm.

even with one set still running JJs, say on the uppers and Duroflex on the lowers it made a difference. I couldn't afford to do them all at once being I had just bought new Savvy arms . I did them a pair at a time both installing the Savvy's and then later swapping to the Duroflex joints so I got to try many configurations along the way along with occasionally reinstalling a pair of OE arms to get the smoother ride back while swapping things around.

So you did run JJs in your uppers and Duroflex in your lowers at the same time.. Interesting.. You mentioned the ride improved but did you notice any odd handling characteristics?

I run JJ's lowers and stock clevite uppers, so I'd gather results would be similar.

I started with just front lowers ( Savvy ) then added rear lowers . Swapped a driveshaft so I then added Savvy upper rears and then upper fronts. I had noticed my suspension felt to stiff so I reinstalled the OE rear lower arms and then OEs went back in the upper fronts which improved the ride. Then I became interested in Duroflex . I put the complete duroflex joints in the upper rears ( left and right hand thread ) which softened the ride so then I reinstalled the Savvy rear lowers , the ride was OK . Next came the Complete Duroflex joints for one end of the upper fronts . Then I started with the lowers , just the rebuild type. I did just the front lowers first in case I felt something in the steering I didn't care for I would still have a set of untouched lower Savvy arms in the rear that could go to the front "if " I found the Duroflex had any negative effects on the steering . That was not the case , it was fine up front so I ordered the final set to replace the rear lowers . The only ill effects I had at any time was a stiffer highway ride than I was willing to accept and that was only when I had 14 JJs installed . Now it rides great , nice and smooth.

When I had JJs on just the lowers ( F&R ) and OE uppers all was still not bad ride wise. When I started adding the uppers is when my ride went down the tubes.

I think I'm going to give the Duroflex joints a try in the near future. For the record I am still a huge fan of the Currie JJ however I wouldn't mind if my suspension was a little less stiff. Maybe I'm just getting old..

He's been raving about them to me, and knowing Connor he takes great pain to make this Jeep handle nice and tight on the road, I wouldn't say he would call the set up with JJs would be what he would describe as "stiff", he has told me that everything is still nice and tight, maybe more so now with the MC joints, but that they do a better job of absorbing shock, all the little bumps and cracks in the road that JJs transfer because of the urethane bushings.

This is a major reason I'm considering these for my Jeepspeed build. Granted that most of the time my rig will be left to DD use and looking pretty, these joints should also help reduce the amount of NVH, keeping as much from being transferred to the chassis, and preserving my precious unibody, both on and offroad.
