This team is top notch! I called them last year about a converter and they jumped on helping me

immediately, even over nighted it to me! Their knowledge is second to none. I recently sent in a

converter for upgrades and they knew exactly what to do and handled it professionally.

This has been by far the most professional experience from a performance company I've ever been with.

It's well worth the wait time of 2 - 4 weeks be it that they are built to order. QUALITY built torque

converter. Exceptional service. Excellent craftsmanship. Superior to all other manufacturers in this field.

Thank you CIRCLED for providing me with the opportunity to use your torque converter in my build.

This company is the best in the business! I have ordered over 6 torque converters from them and the

product is always awesome and the customer service is the absolute best!!
