HYDRODYNAMIC
Rock Stacker
This looks good for a weld on. High and ties into the stock ball joint socket, and double shear.
To improve upon it I would turn lock to lock and determine if the tall misalignment spacers are needed. My guess is no.
I would run low profile safety washers that will reduce the leverage on the bolted joint.
I go my SS safety washers from Polyperformance ages ago.
