KMJ Motorsports products are warrantied to be free from defects in materials and workmanship.  Should your part fail to function we will repair or replace the item free of charge, less shipping to us, for as long as you own it.  Warranties are non-transferrable.  If you sell the part or the vehicle in which it is installed, the warranty will be void at that time.  Alternators with special finishes such as polishing or powder coat will be rebuilt into the same housings.  Physical damage is NOT covered under the warranty.  Any alteration, modification or missing pieces/parts will void the warranty.

Third party items purchased on KMJ Motorsports will be warrantied as per the manufacturer's policy.  Check with the manufacturer to obtain warranty information and procedure.

***To prevent the warranty from being abused, due diligence is expected to make sure our product IS bad before shipping it back.  If you ship us a part and it tests good, we will send it back and the warranty is void at that point.  Our parts are not to be used to "diagnose" any issues with your vehicle. 


- Due to logistics costs, warranty only covers products sold in the US.


Should your purchase fail to function as intended, contact us for an RMA number and return address.  Please include your purchase date and a copy of the original invoice.  All returns must be well packaged to prevent damage.  Any damage that occurs during shipping will void the warranty.  Shipping insurance is highly recommended.  The item MUST be in the condition you received it in.  It must not be cracked, modified, missing parts or soaked in oil.  Any items received in this condition will be returned at your expense. 


 We will make every effort to resolve any issues you may have with your purchase. 


Due to the custom nature of our alternators and the fact that they are built when ordered, they are not returnable unless there is a defect in which case the defect will be repaired as per warranty claim procedure.  

Once an order is placed and parts are ordered to build your alternator we cannot cancel the order.  We usually order parts for a build by end of business on the day of the order.
