The install went very smoothly all things considered. This is a picture of the shackles installed on my truck.
The shackles also definitely upped my wheel travel a bit--this is me on a 30 degree ramp.
I thought these tires would also help me clear my Super Swampers (32x11.50 SSR's, they're 32.5" tall) better, but they don't really--I still rub the fuel line cover on the passenger side whenever I stuff that wheel. Oh well, apart from the annoyance the rubbing doesn't actually limit my articulation (the side lugs brush on the cover on their way past it), but eventually I plan on replacing my stock leaf springs with a set from National Springs anyway (and I'll just make sure they arch more to get me even higher.)
