I installed Dobinsons IMS59-50700 with C59-302 springs and JBA High caster UCA's in the front today. Went pretty easy, did not touch the KDSS on drivers side, loosened on the passenger side, backed bottom bolts out about half way. Used pry bar to push down on LCA on both sides. The long bolt for the UCA is a challenge on both sides especially going it alone but took time and went well. I had already installed new springs and shocks on rear. Alingment tech got caster to 3.5, steering and control is great, ride is a little stiff, feel every bump and crack but people say it will soften up over time. Anyway the KDSS was no issue. I don't have a lean but I did buy the Treaty Oak Offroad spacers in case. Will install either way another weekend.
