I have been searching for lift options for the rear of a 2008 sequoia above the height of 2". I have been told that the only options are "custom coil springs" and am having issues getting answers from Atlas and a few other spring companies. I contacted Bulletproof Suspensions and for their 12" kit, they use a drop cradle for the rear with spacers, however 12" is about 2x the height that I would like to run. I am considering a Zone 5" kit, or a combination of 3" spacer and 3.5 spindle for the front. Does anyone know what the options above the 2" spacer for the rear are available and if a drop cradle would be needed for anything above 2" lift in the rear. The main goal of the project is either 35x12.50x20 on a 20x9 or 20x10 wheel, or possible a 37x13.50x20 with prerunner front fenders while still maintaing a relatively level ride height front to back (not a raked, long travel prerunner look).

I have searched for weeks and have come up empty on most searches and Bulletproof didn't give me the answer that I needed, so hopefully someone has some insight.
