[QUOTE="CD_02TJ-17JK, post: 454489, member: 24561"] Hi KDenn, I’m inclined to agree with BLACKJKU about the adjustable control arms. Before I would reduce the height of your lift, I would throw on a set of adjustable control arms up front, an full adjustable track bar (not a relocation bracket), replace ball joints on anything you aren’t upgrading and see how it rides. You shouldn’t have any issues with a 4” lift pending it’s comprehensive - coils, shocks, adjustable track bar, control arms, extended brake lines, extended or adjustable sway bar end links (make sure your swaybar is parallel with the ground when parked). Also, on my TJ I needed to drop the transfer case about an inch to get the driveline angles closer to factory. Not sure if this would impact the death wobble but I would imagine it could since you're manipulating factory geometry. Also, do you know anything about the wheels for your 35s? Curious if prior owner threw on spacers or if they actually paid attention to correct wheel offset/backspacing. Speaking from experience with this.. definitely not the most mechanically experienced on the forum, so take it with grain of salt. Plus, if you run 35s and you lower to a 2.5” lift you will rub under full articulation with a disconnected swaybar. Not sure of your fender situation, but if you do lower the lift I’d either run fender delete or flat fenders. Good luck! [/QUOTE]
