Take a look here:actually i would like to level out the fj. I would rather spend a bit more and do it rite, rather than skimp and be left out on some trail.
Yeah, if the 5100 is the same length as the OE, but 5100 is actually slightly longer than OE. If the 5100 is the same length as OE, yes the travel would be the same. Just the spacer changes the roll-center of the vehicle, which technically is not safe for off-roading compare to the 5100 setup. Here is a PDF file link to Bilstein's 5100 Height Adjust compare to Spacer lifts. It's all good, we all just trying to help.whether it`s spacer lift or 5100s or adjustable coilovers it`s same travel, limited by length of the shock`s rod. The difference is, adjustable`s and 5100s are work in the similar way, achieving lift by compressing the coil. And spacers...they are just spacers lol. They change the length of coilover assembly without affecting a coil. Suspension travel will remain the same, unless it`s a true long travel suspension. Just my 02c
