Limited Lifetime Warranty

MaxTrac offers a limited lifetime warranty on all of their suspension products against any defects in materials or workmanship. This warranty does not cover finish, racing applications, incorrect installations, abuse, neglect, or use on commercial vehicles. MaxTrac will repair or replace your item at their discretion. MaxTrac will not cover any costs incurred due to installation or removal of products, towing, freight, rental vehicles, or any other incidental or associated cost.


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 professional installation. MaxTrac recommends having your alignment checked after installing new suspension and adjusting your headlights if you have altered your ride height.
