Do I need adjustable uppers control arms?

[LYKOS]

My current springs are shot so I'm going to replace with 'RE 3.5" coils.
For sake of ride quality I want to use LCA drop brackets. Expo, camping rig, mall crawler...

I already have 'RE adj. LCA's. Will I also need new adjustable uppers to correct castor and wheelbase?

Typically, the adjustable lowers are used to correct any wheel base issues, and adjustable uppers are used to then fine tune any castor issues.....

if you have the budget get the uppers, if not, don't. At just 3.5" you can get by with just the adjustable lowers.
