With the age of electronic controls and computers extra power on your diesel rig is now easier than ever with the touch of just a couple of buttons and a small handheld programmer. These huge torque monsters seem to be flooded with all the bells and whistles of a teenage boys’ desire for the ultimate toy. Unfortunately, this huge torque monsters with big nasty wheels and tires do come with some downfalls. The added stress of larger wheels and tires along with the monster torque numbers that accompany it you can easily see how this could wreak havoc on a transmission. Let the havoc be ended now and feel comfortable the next time that Cummins or Power Stroke pulls up beside you.
As technology has advanced through the years so has the friction industry. In the past few years we have seen an increasing demand placed on late model clutch to clutch units, primarily as a result of how easily extra power can be harnessed with the pressing of a few buttons using an aftermarket programmer. In some cases the torque demands will double the factory requirements. When this is combined with the added torsional load of larger tire and wheels it’s easy to see why so many people are left with failure after failure.
This is where the GPZ friction material shines. This latest state of the art friction material was originally developed in commercial and industrial application where constant cycling caused premature wear and excessive heat. While this friction material is incredibly resistant to extreme heat caused by high energy loading it also has a higher breakaway coefficient than any other friction material available today giving it an advanced shift feel. This clutch was also designed to have an extremely low compression rate which is critical in maintaining acceptable piston travel over time for the unit.
The desired endpoint / midpoint ratio remains constant even under increased energy for very smooth yet fast engagements, and on a clutch-to-clutch transmissions this is imperative. This also shows excellent compliance to the reaction plate/ fluid interface and will conform to any surface imperfections for optimum performance.
