Nothing is more essential than replacing OE clutches in the 5R110W in order to increase your vehicle’s performance. With an enhanced shift feel, increased torque capacity, and smooth engagements, Raybestos Powertrain Torqkits are a great additional upgrade to 5R110W transmission performance rebuild kits and are designed to help tear up the drag strip, bust through the mud, and tow towards success. Raybestos Powertrain Torqkits feature Raybestos GPZ material, steel reaction plates, and a set of installation instructions. Raybestos Powertrain GPZ friction plates greatly increase 5R110W transmission performance and durability. This state-of-the-art friction material far exceeds OE material to withstand high stress, high temperatures and repeated cycling. GPZ’s outstanding performance benefits are perfect for heavy-duty vehicles and high-stress driving. Testing of GPZ revolutionary friction material shows that it can outperform certain OE application friction materials by as much as 20%. Plus, its performance improves as the power increases.


This 5R110W Transmission TorqKit Performance Super Master Kit 2008-On may fit but is not limited to the following vehicles:

Ford E-250 08-10

Ford E-350 08-10

For the years 2003 to 2007, the filter is a toilet paper roll type. From late 2007 to 2010 it is a sealed metal canister that installs directly to the transmission case or to the vehicle underbody. In 2011, Ford shifted this filtration function to inside the case. Regardless of model year, this filter must be changed to avoid killing your recently rebuilt unit.
