lift keys with 4"suspension lift

[-spilly]

hey all, i have just lifted my 2006 fx4 level II and am running 33x12.5 tires. i want some more lift out of it because i rub under full flex. i was wondering if anyone else has keyed their superlift? im thinking two more inches of lift from the keys to bring it to six inch lift, and new leaf pack for the rear or possibly 2" shackles. also is it safe or wise to put shackles when already running lift blocks including with the superlift kit. and lastly, would that be enough lift to completely tuck my tires? attached photo is about 85% tucked before totally rubbing, but if i dont rub there is potentially another 6 - 8 inches of flex

Crank your t-bars...it's going to do the same thing as installing torsion keys...Keep in mind you are going to lose travel in the front and your cv shaft axles are going to be crap.

You lift it too much and you're just asking for problems with the balljoints, CV joints, and so on.

I'd either trim the fenders a slight bit, or add a small body lift (or go to slightly smaller tires).
