Q: about control arms

When you buy a kit from RE (like a 4.5 or 5.5 inch kit) they provide control arms that are the correct length for the lift right? If you get Drop Brackets, they are different lengths than if you did not...

When DPG makes a Hybrid kit with ZJ springs that are just a little shorter, the rest of the kit is stock RE5.5. Does the height difference in the springs between the Hybrid kit and the standard kit mean the non adjustable arms will be bad for the application?

Does it neccessitate adjustable arms?

Just Curious.

HarveOut-

Sorry,but RE has only one arm for all their lifts.Adjustables allow to tune your wheelbase and castor!

That clears some things up. But what about DB's? Do they put your wheel dead center of the wheel opening with regular RE control arms?.. or will they push the axle way forward?
