installing these on customer truck with a 2" spacer in the rear of his Eco Diesel Ram 1500 get everything done and let the axle hang and snaps off the locking taps that hold the blocks together. That's another thing, they have to make this product to complicated for what its for. Its a cool design but the plastic as not strong like steel whatsoever. But its our only option I suppose
