My 67 CJ5 has aftermarket spring shackles front and back that look to be 2" over stock. Probably in the past it had oversize tires on it. I plan on staying with stock tires so I don't need the lift and I seem to remember somewhere reading about shackles not being the best way to lift a vehicle anyway. Is that correct? Whats the collective here think about that and also does the lift in any way effect the camber of the front wheels? Keep the shackles I got or go back to stock?
