*Warranty: If after installation there is an issue contact us for a warranty return. This product is NOT DIY. Over 99% of people in the world are not qualified to build an engine, and it is the responsibility of the person assembling and tuning the engine to make sure all the parts are correct and work properly. We ALWAYS STRONGLY recommend parts be installed by a qualified, experienced mechanic. STUD WARRANTY: If for any reason a stud fails during use, not installation, we will send a completely new stud kit. No other parts or any labor are included, and it cannot be converted to a refund or discount on any order. Any part(s) for which a warranty claim is made must be sent back to us for inspection, NO EXCEPTIONS. We cannot warranty anything based on photos, emails, phone calls, or what you read online alone, or what another mechanic says the problem is. Warranty does not cover any failure that is a result of improper installation, tuning, break in, lack of maintenance, or misuse.
