Hey all! I used to have a 80 series land cruiser but needed something more updated and wanted to go more for of an overlanding build so I bought a 100 series( 2006 Lexus LX470)! I am still learning about this ACH system I have on this rig but I would like to put a swing out rear bumper on and a metal front bumper on as well. Is there anyway you can install heavy set springs without loosing the ACH? I was looking into the dobisons 1-1.5in lift kit for this Lexus but would that hurt and or make me loose the ACH system? Lastly can the bigger diffs handle 35s from the factory? I have 33s on it now a fresh set of KO2S. I will admit the front bumper is strictly for looks but the rear bumper would to hood the spare and extra fuel/water, also so I can remove the spare tire from under the rig. If anyone has done a build close to this please share I can’t find anything on this! Thanks for the long read!
