right now im running deaver f31's flipped factory shackles and stock shocks... and DAYUM! new springs alone made the ride better, the pre load in the springs pushes the axle to the ground keeping the tires planted nicely!
ive hit some RR crossings at a good rate of speed and when i would used to feel the *** end get light and bounce around it just sticks now!

cant wait for the new shackles and shocks

 

Ran them for a few years, and they were great offroad. There is much les wheelhop, though I also removed the block. Make sure you extend your missing bumpstops if you deleted the OEM block. Your shocks will be your uptravel bumpstop, ask me how I know

Had to get rid of them just recently actually, when the truck went back to hauler, not offroader. They are horrible if you carry more than 300lbs in the bed. But, gotta lose that for the great offroad performance I guess.
