Ultimate Converter Concepts - Custom Torque Converters

Our Move was completed ahead of schedule.

We are open for business, rolling and ready to serve.

Please call or email lenny@ultimateconverter.com or montgomery@ultimateconverter.com if you have any questions about our terrific new facility or anything else.

Ultimate Converter Concepts was conceived with the idea of producing the finest, most durable converters available on the market today. Unmatched personal service and consultation take the mystery out of torque converter selection. It lets you, the customer, come away from your experience with Ultimate Converter Concepts, with the satisfaction of knowing you spent your time and money the right way the first time.

Just a few new additions to the menu, all billet Aluminum Bolt Togethers, from 7” to 10”. A nice complement to our Half and Half Bolt Together line and our weld together line. I believe we have the right piece for most all the combos out there.

I have alot of customers all over the country, and have used Lenny's converters for one reason, he is the best! I can give him the numbers of my power and torque, and he gets what I need right away, you can't beat his service either, he is quick and efficient, and being a racer I know all about this. Thanks.

Dear Lenny, I would like to sincerely thank you and Ultimate for providing me with the fastest and most consistent torque converters I have ever owned. As you know I race both Pro Tree and Full Tree. Your converters are the only ones that I have been able to be dead on, whether I'm on the stop or flat out. Your converters have helped me win multiple races, and most recently, the SGMP Super Buck Blast. Thank you again.
