Many folks modified the OEM 4th gen part with the "drill mod" in order to increase the flowrate through the MC. Are any other similar modifications needed for the Dorman part?

Carl off memory I think that restrictor was in the stock hydraulic line. Going to the Earls parts with -4 line opens the circuit up.

Some automotive development information. The restrictor is the stock line to help protect the driveline from snap clutch applications. With the restrictor you can’t run the engine up to redline and dump the clutch. The restrictor controls the apply rate of the clutch. If you get rid of it your system reacts faster. Downside your driveline loads go up and you break more parts.

Thanks Mark.

BTW, the Wagner replacement MC is made by AP but I too like the aluminum Dorman part (on order....).

Awesome info, great detail.

1) What throw out bearing are you going to be using?

2) For the cruise control, is that only compatible with a factory ECM and not for something like a Dominator?

I’ll use a Centerforce throw out bearing and clutch. I think their throw out bearing is a Ford parts with a bit more stroke. But I could be wrong.

Not sure on the cruse control. Call Dakota Digital. They have a good tech line.
