Why is it that a 3/4 drop only drops a L 2/3. And a2/3 only drops1/2??

 

a 3/4 kit will drop a lightning 2/4 and a 2/3 kit will drop a lightning 1/3. the reason being that a lightning comes from the factory lowered 1 inch in the front. but the rear is normal f-150 height. if someone gets a 2/3 from a 3/4 kit or a 1/2 from a 2/3 kit its because they didnt bolt the shackles to the lowest setting.
