Most people, when they upgrade their suspension also upgrade their tires. Larger tires increase traction and true ground clearance as well as provide more sidewall area, so you can run lower pressures. Increased leverage from larger diameters and increased traction from aggressive off-road style tread patterns quickly overwhelm stock steering dampers.
The valve profile in the KORE RACE SERIES STEERING DAMPER was developed to provide continuous control during the most punishing situations imaginable - big tires at low pressures on rough terrain for long distances.
