well the blocks are made to fit our size shocks and so are the 412's, so they should "FIT"...."work"? is a broad term cause Im guessing the blocks lower the rear around 2" and the 1" shorter shocks would make it 3" which I dont think leaves enough room for the tire to move up and down. And the shocks are 1" lower based on the stock geometry but when you change the geometry of the shock angle with the lowering blocks 1" could mean something different. And then of course you figure that being that low would cause a need to have the shocks on the hardest setting to avoid rubbing your tire, and if theyre that hard then whats the point of having premium shocks? Not to mention the fact that those blocks change the angle putting more upward pressure on the side of the shock not the bottom, which would most likely bend the piston/rod of the expensive aftermarket shock.
Theres a lot to mull over. If you want it low youre gonna want it to ride like a pickup truck. I have cut springs on the hardest setting to prevent rubbing with around 2"+ overall lowering. It rides like a hardtail with a little bounce.
