saw a thread on them the other day, how hard are they to install urself, what has to come off the truck? that post sounded like they were well worth it

 

If you have average mechanical knowledge and are willing to follow the directions, they are easy to install.

You will need to remove the trans pan, valve body and shift linkage.

When installed correctly, a shift kit can be well worth it.

 

ok i should be fine for the install, what do they do? i mean what will i feel and see different after install? any mpg binifits?
