Description
If you bought a cheaper level kit that did not come with any caster correction, then you need these. Proper caster also helps prevent death wobble.
When lifting the front of a Super Duty 2.5″, caster will be reduced by 1°. The 2° shim specified with our 2.5″ lift systems not only restores caster but increases it by 1° from the stock spec to ensure proper tracking with larger tires.
