Installed the Detroit soft locker about 3 weeks ago. Very satisfied. I have an old original version in a street strip car and never had a problem but it is noisy can hear it ratchet around turns. This soft locker I can't hear ratchet, but I can feel it when it locks and unlock on the street. Not an issue for me as I knew what to expect. Off road it was worked Awesome, if you are on the gas it is locked. 100% what I expected.
