Here's a great blog post that explains and illustrates Toyota's KDSS (Kinetic Dynamic Suspension System), as found on the Land Cruiser. Edmunds' Straightline blog found the KDSS system gives the LC 200 series 25 inches of wheel lift, best of any stock vehicle they've tested to date (including a Wrangler X). The system is simpler than I thought, too.
