FTI Performance MR Series Torque Converters
FTI Performance MR Series torque converters are specifically designed for mud boggers needing an incredibly strong spragless unit without draining the bank. They're ideal for 400 to 1,200 hp weekend runners—and still perform well during occasional races. Features include a forged billet steel front cover, a billet spragless center, a hardened flanged impellor hub, and a steel anti-ballooning plate.
Triple Torrington bearings, computer balancing, and furnace-brazed and heli-welded fins add to the list of reliable bulletproof MR Series parts. These converters provide excellent torque multiplication, better heat-dissipating oil flow, and impressive performance. Order the parameters desired and the model recommended for your transmission application.
