Bar Keys Works Best in Lifted and Leveled Applications

Maximizing ride height on your GM 6.6L Duramax has never been made so easy with the 2020-2025 GM 6.6L Duramax Cognito Torsion Bar Keys. These torsion bar keys will properly add front and rear ride height, so that you can leave an adequate amount of droop travel to maintain superior ride quality and handling. Depending on the spring rate of your truck, you may not need these torsion bar adjuster keys to reach maximum ride height, but leveling or lifted applications will need these to reach the higher settings.
