Anyone running the Teraflex long arm on a 3.8L JK will notice the front control arm mount brackets, particulalry on driver side, are very close to the exhaust & lower catalysts. Combined with the cat Teraflex's upper control arm flex joints are rather small (probably too small), the heat from the exhaust & cats causes premature failure. Taking a cue from the Factory, who have installed upper control arm heat shields on recent model 3.6L JKs, I decided to try insulating the Teraflex mounts. I used some DEI 50501 stuff from Summit. One test drive shows promise, the arms & bushings were cool enough to touch, particularly on driver side. If you're chewing up Teraflex's expensive bushings with regularity like I was this may be your fix.

 

Nice install/solution. Looks good!

 

Thanks! Time will tell. If this doesn't work I'll be making a change to another brand's front brackets, joints & upper links.
