What is the best way to lower my supercrew and keep the factory ride and not effect pulling a trailer??????? thanks

 

How much do you want to lower it and what are you prepared to spend?

 

I would like to run the 17" wheels i have on it now.I really don't know how much to lower it 2 front 4 in back??

 

You can use either a-arms or coils for the front. For the rear you can use Hotchkis leafs for a 3" drop or it you want 3-4" inches, you can use a hanger/shackle setup. Then, for your towing needs, add a set of helper air bags for when you tow or haul.
