Raf, if you're breaking your shackle mounts, I recommend taking your two front shackles (rears shouldn't be a problem unless you're breaking you frame!) and cutting out those cross bars that make your shackles an "H" shape. Replace them with a sleeve of the same width and then run a bolt through those sleeves (of course, you'll need to drill holes in the middle of your shackles now). For street use, keep the center bolts tight but for off-road and ramping, loosen them up to allow the shackles to twist sideways like a parallelogram. That way, the shackle mount on your frame doesn't become so much of a pivot point.axle said:Con - during high RTIs, your frame mounts may not be able to handle the leverage produced by oversized shackles. Mine are only 2" over, and I've broken BOTH sides within one year of installing them.
