Torsion bars up front, leaf springs in the rear. I had a 2002 with a 3" Calmini suspension lift and 3" BL and an ARB with WARN8000 and i had a ton of sag with those torsion bars! Not a fan of torsion front setups, coils are a much better ride and easier to work with.
The previous Land Cruiser (TLC 100) had front torsion bars....
