Dr KDSS Control Harness Kit (Harness Only) for 4Runner (2010-2024) & GX460 (2010-2023)

The Dr. KDSS Control Harness puts you back in control of your KDSS system, allowing you to tune how your suspension behaves on-road and off-road instead of relying on factory logic. Built for drivers who actually dial in their setups, this plug-and-play harness lets you electronically open and close the KDSS hydraulic valves, helping correct KDSS lean, smooth harsh behavior, and tailor ride quality to real-world conditions.
