Cognito torsion bar keys enable front ride-height adjustment for leveling and lifted setups on 2001–2013 Silverado and Sierra 2500/3500 2WD/4WD trucks. They’re used to attain higher settings within a lift kit’s range—such as taking a 4-inch Cognito kit to the 6-inch setting—while helping maintain droop travel and ride quality. Forged steel construction, raw finish.
