can i run 6.5 in lift coils upfront with 4.5in LCA (the fixed bent ones) and stock UCA? I alredy have an adjustable track bar. And a drop pitman arm. Do I need adjustable control arms?

 

I'm like 99% sure you will need adjustables. You should just get some LA's

 

You can use stock uppers all they really do is adjust the pinion angle. Lower 4.5s should work but i would suggest longer because the axle might sit back pretty far

 

You can and you can also just weld in a 30" pipe as a coil. None of these are suggested. With uppers that short your axle will be pushed back almost 2" and your yoke will face the ground when you flex and brake.
