Those might be fine for a drag car but they will limit your flex, make your springs bend in funny ways they aren't supposed to as the suspension cycles, and eventually break at the weakest link. They will fight the axle's need to move slightly forwards and backwards as the suspension moves. Compression pushes the axle back, droop makes it need to move forward, relative to static height. This is why a shackle or something equivalent is a must on a traction bar for a vehicle with a lot of flex. It allows the axle to still move forwards and backwards.
Use a proper ladder bar. There's lots of bad ways to do anti-wrap/traction bars - this is one of them.
I knew a guy who used to use chains in a similar manner, which solves the issue with droop, but doesn't solve the compression problem. They also kept tearing off at the mount or ripping a chunk out of the axle tube. He said it was the welds, but it was the design - it sucks. Eventually he ditched them.
