Quick bring on the LOST LIFT DON'T KNOW WHAT TO DO Emergency Squad we have to help this man quick!
Its kind of a personal choice really
Frankenlift you just unbolt the old and slam the new in and done, front will be done in an hour
rear is the same either way so that doesn't make any difference
As far as ride the Frankenlift will be somewhat more firmer riding just due to having the spacers compressing the springs somewhat more, also may have more strange noises at first till it gets broke in.
Doesn't cost that much to have someone compress the springs, my local shop does them while we do the rear bumpstops and coils so not any real lost time.
Frankenlifts are somewhat harder to install so you'll need some good rachet straps to pull them in
Just all depends though on what you think its worth to you
either way you can get almost the same amount of lift so that doesn't matter
ease of installation is what it boils down to
