Adjustable rear upper control arms

[weekendclimber]

Hi
I have a 2004 V8 Sport 4wd.
Recently did a Dobinson 3.5” lift all around.
I have 32” tires 275/70/17’s

The rear springs I have are Dobinsons
677V coils.
The rear can be 4” lifted when totally empty.
My stock bushings are shot and there is some arc on the rear coils flexed in position.
What adjusted or set difference should I have length wise on new
rear LCA’s ?
and UCA’s ?
for this type of lift to get the axle angle in the best position?
What brand is recommended?
Thanks.

Might get better traction on this question over in the 4th Gen section: https://www.toyota-4runner.org/4th-gen-t4rs/

What shocks are being run that allow 6” extra down travel? Stock length is 21” extended, So you’d need a shock running 27” extended, or modified shock mounts.

You’d need a hell of a rear brake line and some way to extend the E-brake cable to deal with that kind of axle down travel.
