The Cognito Economy leveling kit uses forged steel torsion bar keys and 1/2-inch shock extenders to raise the front by approximately 2 inches while retaining OEM upper control arms and adequate droop travel. It supports up to 33x11.5-inch tires on 9-inch wide wheels with 5-inch backspacing and improves vehicle stance without aggressive geometry changes. Installation is a typical DIY job of about 1.5 hours. Made in the USA.
