[QUOTE="ntm, post: 980252, member: 2412"] Upsides to a sprung under is more available droop travel. Downsides is more pinion angle change, more axle wrap/hop, and less accurate location of the axle laterally under the truck. This is a result of using a longer overall spring, with more arch. Usually people don't notice this when going sprung under due to changing to a bed cage and some larger, longer bypasses at the same time. The behaviour vs something with links or shorter leafs is very noticeable on corner exits, the sprung under feels a bit unstable, and tends to "wind up" and break traction under acceleration. But of course, if you want the travel with leafs to improve performance through the whoops, you pretty much have to go sprung under. [/QUOTE]
