PROTORQUE PERFORMANCE PRODUCTS 1,000-2,000hp U9 Converters Now Available

ADVERTISEMENT

PROTORQUE PERFORMANCE PRODUCTS has introduced a revolutionary new torque converter to its current lineup. Developed specifically for 1,000-2,000-horsepower street cars and race applications including Ultra Street, NHRA Factory Stock, NMRA Renegade, and more, ProTorque’s U9 torque converter is now available for GM TH350/TH400/Powerglide 30-spline transmissions.

Building on the same cutting-edge technology found in ProTorque’s wildly successful Revolution series converters, the U9 series is the next step in the evolution of performance torque converters and progresses torque converter advancements even further.

ProTorque originally created the U9 converter as a replacement for traditional 8-inch or 9-inch converters used in racing for the past half-century. After extensive testing, however, ProTorque discovered that its U9 converters have more capacity than any of its predecessors and are perfect for the 1,000-2,000 horsepower range. ProTorque’s U9 converters are bigger than a traditional 8-inch and smaller than a traditional 9-inch, but still support more power than either other unit.

The U9 converter from ProTorque is unique in that it offers a tremendous level of flash stall while still locking up to only lose a few percent out the back. Additionally, a newly designed, all-aluminum machined back cover is built to be exceptionally strong yet surprisingly light. ProTorque continues to push the envelope in all types of performance torque converter technology, and the new U9 series enables racers to benefit from the past decade-plus of innovation.

With nearly two years of dedicated research, development, and on-track testing and refining, ProTorque’s U9 program has found great success. Because of the wide power range the U9 converters support, racers in a variety of classes have been able to win races, secure championships, and set records. Drivers like Ron Rhodes, Joel Greathouse, John Kolivas, Frank Varela, Haley James, Geo Castillo, Carmen Damiani, JJ Da Boss, Lou Iacopetti, Martin Connelley, and many grudge racers all trust the U9 converter to get them to the stripe first.

 

U9 FEATURES:
