Woltjer motors are always proven fast, reliable, "LEGAL" National winners. In addition, they are incredibly professional, motors are always shipped as scheduled and VERY reasonable.

Call us for all your Woltjer needs, whether it's a new motor or motor work, blueprint, etc. We'll e-mail or fax you a UPS shipping label and letter to enclose in the package. Motors are shipped DIRECTLY to Woltjer and shipped DIRECTLY back to you. Fastech will send the bill along with the original Woltjer invoice.

There is ABSOLUTELY ZERO MARK-UP  from what Woltjer normally charges. You have nothing to lose going through Fastech. You will only get better service, turn-around, etc. We have all the tuning notes you will ever need, but if necessary, Woltjer is still available for questions. Just tell them the motor came from Fastech, but in most cases, the response will be the same as what we will tell you.
