I have a 93 ranger i am wanting to replace my stock mono spring with explorer springs and an axle with 3.73s. I know this will lower the rear as this is part of my goal, my question is on the fron will all i need is the lowering ibeams or woll i need coils as well? I plan to do the bolt-in Explorer parts the rear shocks will i need lowering shocks for the front? And if i pull the speedo gears out of the explorer will this correct my speedo after the gear change ( 3.45 to 3.73?
