Since MaxTrac suspension components are designed to replace or enhance your existing suspension, there is no cutting or other modifications required to ensure a proper fit. You could install your own suspension, although we do recommend having a profession installation. MaxTrac recommends having your alignment checked after installing new suspension and adjusting your headlights if you have altered your ride height.
