Lets say there is 1400 lbs total rear wt., and, your rear un=sprung wt is appx 600 lbs. That means that the 'spung' weight on the rear axle is appx 800 lbs. So, your rear un-sprung weight percentage is close to 75% of sprung weight. This = disaster in the suspension world. 50% is the max for anything that handles. To get there, you could A) add 400 lbs to the rear sprung weight (this is why duallys ride better with 1000 lb of crap in the bed), or, B) swap to a lightweight 9" and 4-bar, and light weight wheels/tires. - I know, neither of these is going to happen. - But, now you know what your up against. Go with big sway bars and good shocks (try off roar pre runner valve styles) don't worry too much about the springs.

So if you have flipped the axle does this change the unsprung weight of the axle?
