I’m working on getting everything needed to lift my kk 4” I’ll use my spacers from my 2” lift along with the front strut plate I have 2” lift OME HD coils and JBA upper control arm and JBA track bar. Every thing for the rear I have I just need the front struts but I can’t find info on what size struts I need for the front.

First you are starting out all wrong from the get go
Or are you just wanting a lawn ornament ?
You can not go four inches the way you want to
You must use aftermarket coilover so there is not spring/ upper control arm contact all the time
Plus we have shocks for the front, not struts, struts are used on cars with no upper control arms.
We have upper control arms
For the front if you want 4 inches of lift, use jeepinbyal adjustable coilovers
for the rear do you already have an adjustable track bar and extended sway bar links, you need them as well
Now start from there and we'll fill you in on what else you will need like regearing etc
