So, I had the bumpers and other stuff installed, including the front trackbar bracket. I still wasn't satisfied with how it drove on the street. At the time, I had:
Pro Comp 4" Stage-II Lift Kit with MX-6 Shocks;
J.E. Reel 1350 Front DS;
Rancho Steering Stabilizer;
Synergy Suspension Front Track Bar Bracket;
Synergy Suspension Jeep JK F911 Hardware Kit; and
Teraflex Exhaust Extensions.
So, I took a gamble, and just added:
Synergy Suspension Jeep JK Front Track Bar (replaced ProComp TB);
Synergy Suspension Adjustable Front Lower Control Arms (replaced fixed ProComp LCAs);
Synergy Suspension Chromoly Tie Rod; and
Synergy Suspension High Steer Drag Link (flipped).
Dang! I'm really not kidding: it rides like an independent front suspension Tahoe or something now, but has even more potential articulation than it did before for the fun off-road stuff. It's like night and day. Before, it was fine, and I was used to it. But now, I don't feel the bumps and it drives like a Lincoln Towncar on the highway. Glad I did all that, though it wasn't painless.
And I added a winch:
I'm done for a while, but the installer (High Tech in Chantilly) is going to fabricate for me a permanent metallic fix for the Transfer Case Bushing debacle: http://www.wranglerforum.com/f33/not...eel-99139.html
He's looking at something metal and removable, but will essentially will be bolted in place.
FWIW, the best the installer could achieve with the previous parts was a caster of 3.36*. It's now set at 5.15* (both averaging left and right).
Thanks to OAD Offroad for the good advice and prompt shipment of the parts.
It drives like a dream now.
