Do I need to lengthen my drive shafts and extend brake lines with a 6" lift?
 

I have a 1987 chevy V10 short bed with a 4" suspension lift on it right now. I'm wanting to put a 6" rough country all spring lift on it but I'm wondering if I have to lengthen the drive shafts, and if I do have to lengthen them, how many inches do I have to. Also do the brake lines need to be extended if I install the 6"? Thanks I would appreciate it if someone could help me with this.

you will definitley need longer brake lines
driveshafts are a whole 'nother thing. put your lift in & measure. you dont always need to lengthen your d.shaft, easier & cheaper to get a longer slip with a hi-angle yoke.
my 8" lifted crew is running the stock rear shaft, t-case 1" drop, 1 1/2" carrier bearing drop, & shackle flips really help with the angles too. front shaft is stock too, clearenced stops, & a longer hi angle slip.

I would rather have two driveshafts cut for it,They will be a lot thicker and handle more power.Most big diesel shops can make you a driveshaft about 300 bucks but rated to lie 500hp.
