We don't offer rebuild kits for our suspension products due to liability reasons. Instead, we require the suspension to be sent to our facility for rebuilding. Our suspension comes with a lifetime warranty for the original purchaser, covering parts and labor for rebuilds. If you're not the original purchaser, we still offer affordable rebuilding services. All repaired products are subject to a return shipping fee. To have your suspension sent in for repair, submit a warranty claim using this link: Warranty Form
