im putting in some new springs that are 1 inch longer than what i have now, so the question is how much of an angle can i have on my shackles. right now they are sittin / about like that.

I've found that mine works best at an angle like \ that. Yours must be inverted.
























Actually mine are at about 30 degrees.

you'll be fine, and it'll flex better now.
