i recently added 2 inch spacers and shackles to my 4.5 suspension kit.
i realized i needs longer control arms.
do i need larger upper and lower contol arms?
or just the lower?

i looked at the rustys long arm kit but its expensive as hell
any tips?
any help is much appricated.
thanks

 

yes you do, or cheaper buy a set of drop brackets and braces. they will make your ride better than adding longer control arms.
