UPDATE:
1) So, Bad News... My Synergy DDB JK Axle bushings came in and the inner metal sleeve is unique and will not swap with any other M10 bushing, SO I ordered JK replacement yokes for the control arm and M12 bolts for the front axle bushings... I guess this is the cost of running discontinued platforms. Not bad at $40 a pair. These are the last bushings i need to replace (and not looking forward to it)
2) Swapped mt front Pro-Comp 2" springs with OME 933 HD Springs in the front, Ride is noticeably smoother and almost "fluffy" feeling with my 5000x shocks. reminds me of the old school OME Nitro chargers. AMAZING! I did not expect this because the rate of the pro comps are 170in/lb and the OME are 140in/lb, i didnt replace them for the rate change i needed more free length.My headlights that were properly adjusted with the Pro-Comp springs and now point way high, i didn't do any measurements but the headlights tell me that the springs provided more lift (bonus). The reason for the swap is that the Pro-Comp springs were about 2" too short for the amount of droop provided by the 2.5" Rancho 5000x shocks, the OMEs are LONGER and wont lose contact with the spring seat when fully drooped.
3) These DDB bushings are STIFF, i couldn't flex the bushing with a large screwdriver, while the stocks looks like a marshmallow when flexing with a rod. This results in more suspension energy going into the shocks/suspension. the roughness and shuddering of going over a poor road is ALL handled by the suspension now and feels quite nice and super controlled. NOTICEABLE difference from rubber. Nothing harsh, quite the opposite everything controlled and the suspension absorbs this energy instead of wiggle/shuddering as the bushings jiggle.
I can see these bushing being the future and a be-all-end-all for most of us IF IN FACT THEY LAST (Big IF), longevity is something yet to be seen as they are so new, But in the past polyurethane has been terrible, stiff, squeaks, fall apart when flexed, rip of our axle mounts, etc etc... However OEM's are embracing the bushing with factory performance parts (read that mopar JL lifts use these), so this is a good sign for reliability.
My TJ is a daily driver and lots of fun trips during the year here in AZ. I am by no means hard on my rig but it exercises quite regularly. If these indeed turn to crap in short order, Currie here I come.
