Welcome to the forum. Read through the first few pages here.

Yes you can run 35 inch tires with it

 

Maybe.

Removing flaps. And depending on wheel offset as well.

OP. You don't need a 3.5" lift to run 35s either. And there are much better options than a RC lift. There's a reason their whole kit costs barely more than just a pair of 6112s or SPC UCAs

 

If I was running 35's, I would invest in a better lift. Just my opinion.

 

You should look into bilstein 5100 or 6112 if you are on a budget or a westcott designs lift kit
