In higher lift instances, Alpine IR Long Control Arms retain near factory orientation to reduce bushing stress during extreme droop as well as reduces shock load transferred through the control arms. The front track bar and rear track bar brackets operate in unison to enhance steering response, optimize vehicle roll center, and reduce body roll substantially for unsurpassed handling.
