Wire Harnesses and Alternators are covered by a 1 year warranty from the purchase date. There are no other representations, warranties or conditions expressed or implied, statutory or otherwise except those herein contained. Warranty does not cover any defect which is the result of improper installation or modification of the system or any of its components by purchaser.

Alternators output is determined by engine speed and pulley size. 1-7/8″ serpentine pulley will VOID alternator warranty claims caused by excessive RPM.

We do NOT keep credit card numbers on file, because of this we can not add to your order or alter the amount charged to your credit card. Make sure you give us your telephone number if you need to change or cancel an order.

If you order an item that is listed as Backordered you are reserving one from the first shipment. We can not guarantee delivery dates on items backordered from our suppliers.

We will gladly refund your order if you are unable to wait for the backordered item.

RJM Injection Technologies charges $60/hour for vehicle repairs. We are unable to help everyone for free by long distance correspondence. Some problems require experts that can physically diagnose and repair the vehicle, we are not e-mail mechanics.

You are also responsible for Local, State, and Federal laws that may prohibit tampering, removal, or disabling any emission control device such as the fuel injection system.

We no longer ship outside the USA. We have been stuck paying import taxes for customers, last thing I want to do in life is pay taxes to other governments.
