You could lose the lift block in the rear and install the axle relocation plate like you said. A win/win I think. If you need to regain lift after that then you could add another leaf or a bit longer shackle, or drop the front to match.
Or you could let the back sag like 4runners all did. Mine does and I don't care. I wouldn't drill the springs. More likely to fail and a huge pain.
Love the build.
Thanks man. yea I've kinda been concidering that. You have a very clean 4runner. Who makes those flares?
Anyone else have any idears on how to move the rear end back easily?
thanks
