Those look nice...you do great work!!...however, I have the Blue Ox Sway-Pro WDH which doesn't have grease on the spring bars...the grease stays in the fitting where the bar end connects to the receiver hitch head, so the bars stay clean. Plus they are just straight bars with no angle to them and with a chain on one end. If you ever decide to up grade your WDH, I would suggest that you take a look at the Blue Ox Sway-Pro. They also have the sway control built into them...but duh!.....you probably figured that out from the name....silly me!
As for the spring bars...I just put them in the back of my truck whenever I take them off. They are so easy to operate....
Just don't lose the wrench!
