Lonestar Warranty Policies

DOT 5 WARNING

USING DOT 5 BRAKE FLUID WILL VOID WARRANTY! CHANGES IN CHEMISTRY WILL HAVE ADVERSE EFFECTS ON BRAKE RUBBER AS PER EPA RULE.

See item listing for warranties. Warranties vary by part but Lonestar will stand by each and every part that we sell. If you are not completely satisfied with a part contact your sales representative for instructions. All warranties must be shipped in before a replacement will be sent out or we can charge you for replacement part and then do a credit when warranty is received and verified. We know this is an inconvenience but it is necessary so that we can determine what is wrong in order to stop it from happening in the future.

NEW CORE POLICY - PLEASE READ AS THIS WILL AFFECT YOU!

Please make a note of our new core policy. Due to the large amount of non Delco cores being returned to Lonestar we will no longer be able to issue core credit for the non Delco caliper cores unless you are willing to take back remanufactured non Delco calipers. I hope this is not too big of an inconvenience.
