1.75" is the setting... you may feel nose high so keep in mind a 1" cornfed spacer is 3 times as much as a daystar 1.5" spacer. Set the front 5100 to 2.5" and get daystar 1.5" rear spacers ($40).
This situation seems to keep coming up so I thought I would post info to clarify the fit on the rear of '10 - '16 4Runners. Please delete if not appropriate.
According to Toyota, there is only one part number for the rear coil spring bump stop/isolator on the '10 - '16 4Runners. Having said that, we have found that there are in fact 2 different dimension parts. I've attached a chart showing where to measure to make sure you get the correct parts.
If anyone has any questions they can call Daystar at any time at 800-595-7659.
