Your link doesn't work but that lift is a spacer lift and while it will lift your truck it doesn't address the axle shift that will happen or the loss of Castor from the lift...

Cary,
Can you explain more a bout the axle shift and the loss of castor? Also, have you ever hear of anybody putting the dually (2") blocks in a SRW 350 to get the rear lower. Would have that the same problems?

Thanks,

Changing the rear blocks shouldn't cause any problems just make sure your shocks don't bottom out.

The front end when it cycles allows Castor change as it pivots from the end of the radius arm. Lifting it reduces the castor thats why most manufactors provide a Castor ball joint shim to get back to stock castor with a level kit.

The axles in SD's have a track bar and this keeps the axle centered at ride height, when lifted the axle shifts since the relationship of the suspension is like a tringangle..geometry ..change 1 leg it affects the others so to keep the axle in its correct location the track bar needs to be longer..or a correct drop bracket for the exact lift your installing.
