The Kit I got didn't come with one and I'm just curious if it is required?

 

Most I have seem will give you directions to knock out the stock roll pin. Move it a set amount drill it and put the roll pin back in.

 

Yes your kit should have come with a 1" extension, The kit i bought was from summit and they do sell parts to the kit.
