This is what Offroad Designs says about theirs:

Load carrying ability is also a common question. Basically, if you keep the factory overloads, you won’t have any trouble. We've designed the shackle angle to retain as much load carrying ability as possible with a lifted 4wd.

There is no more lateral lateral motion of the vehicle than with the stock tension shackle bushing setup. It may look as if the axle could move side to side easier, but the only thing that puts more leverage on the bushings is the additional ride height, which you also gain with blocks or lift springs.

1-ton trucks require a different flip kit than k5's, k10's and k20's. The kit is the same price, we just need to know it's for a 1-ton when you order it. The difference is that the spring center spacing on the 1-ton axle is only 40 1/2", and on the rest of the trucks, it's 42 1/2". The brackets are a different shape to reflect that.
