An introduction: 2002 “Pre-lowered” manual transmission Liberty sport 4x4 sagged down to 17.5” front 18.5” rear. All stock zero modifications. So after many hours of reading I settled on a configuration that will hopefully work for me. I know everyone here swears by OME products but the cost was substantially more in Canada. -Front And Rear H&R adventure springs 1.5” Lift -Front Bilstein -Rear KYB Gas-A-adjust (Dodge Dakota length) -Hockey Puck rear bump stops (x2 per) -Still looking for more info on front bump-stops (available locally) -I will be “tweaking” the height with, custom rear spacer pucks nestled between two factory upper isolators. Probably 3/4”. This I will machine out of a product called King Starboard. The front I will be cutting out a set of aluminum 1/4” over the top spacer plates with my new plasma/cnc table. Anyone willing to share the plate file ? I will reserve the Clevis lift to adjust and even to rear. Now here is the Question: I found a additional spacer in the factory front suspension. I need verification if this is a factory “Easter Egg” or meant to be there. In-between the upper spring isolator and top shock mount is a 1/4” thick steel round plate. This spaces the isolator away from the upper mount. Was this where “Pre-Lowered” gets the extra 1/2”-3/4” ? I cannot find this spacer in any parts diagrams. I am 99% sure this is factory original and never been a part before. Any input ?
