This is the only way I have found to truly keep the axle perfectly centered when cycling up and down. I have done it this way for years and have always got the desired results setting it up like this and never had any issues. I have tied doing what you have suggeseted before and it has always ended up shifting to once side on full drop down or full lift about a 1/4 of an inch and some times more depending on the extent of the lift. I am not saying your way is wrong, maybe it works for you but with the system I use to set everthing up it has always worked pefect for me when doing a watts link and has always kept the axle centered.

With tripled bags an range of adjustment im unsure if the swivel reeds to be that long.i imagine that at vertical its at the least amount of resistance possibly. But its at the highest lowest point taking more space from bottom of frame(ground😉 )and the bed causing more more fab work. If its angled it woukd decrease the distance vertically between top and bottom swivel points which makes your bracket closer top to bottom . At mid or ride point whatever angle u want or space trying to achieve the measurement vertically from top to bottom of the propeller(swivel) your frame bracket have to be identical to be parallel. As long as thats tru shouldn’t have any uneven movement🤷🏻‍♂️yea?

shocks were mounted on the front side of the rear axle up to the c notch tube crossmember
