End to death wobble
I purchased the Readylift off road trac bar for my 2012 F 350 4x4. I had installed heavy duty shocks and steering stabilizer which worked fairly good until the tires needed rebalenced. Now I do not need the steering stabilizer with installation of the trac bar. It was expensive but the peace of mind is well worth it.
Low grade mounting hardware
The helper springs seem to be of good quality, but the mounting hardware was low grade. The threads on some of the nuts tore while trying to remove the assembly for some maintenance, and one of the U-bolts broke. I also noticed that the plates were slightly bent. I followed the instructions to the letter, torqued the bolts to specification with a new torque wrench. Overall I was just very dissatisfied with the quality of the mounting hardware.
