ProTorque Powers Up With New X8 True 8” Performance Converter (

Using the vast knowledge Joe Rivera gained over the years from outlaw-style drag racing, Pro Torque created the X8 to perform like a lock-up converter without actually being one. The specifics behind the secrets on how they've accomplished the feat are closely guarded, however, as ProTorque and Boninfante collaborated to manufacture the X8 torque converters in-house using proprietary processes and intellectual property.

“All of our products are born from Top Fuel technology, and the stator development has been the key to this entire program. We created a converter that has enough slip and flash stall to get the engine in the right place with more efficiency than any of the other platforms currently available,”  – Joe Rivera, ProTorque

The X8 is currently being produced to fit the GM TH350, TH400, and Powerglide 30-spline transmissions - expanded applications will be coming soon.
