Hello I plan on putting an FP black soon in my car and i want to reinforce my drivetrain what shop sells a kit to reinforce the transfer case ?

I have an Evo 4 so the evo 8 transfer case wont work but maybe the internals.

 

I would call shep trans to see if they might have something that can help you with your build.

 

shep does build evo 4tcs.also you can change your evo 4tc with a evo 8tc.if you can get the draft (i believe thats what is called)and i dont think the internals are interchangeable the evo 4 internals are smaller.gl
