Installation

Allow about 3 hours, plus or minus 0.5, not counting alignment or wheel and tire assembly. ReadyLIFT labels it do-it-yourself but recommends a certified mechanic. An alignment may be required, headlamp aim must be checked and adjusted, and ADAS may need aim or function checks; some require dealer tools.

Modifying your suspension can change handling (SAE J2492). California Proposition 65: ReadyLIFT lists DEHP.
