My 2.0 spring worked flawless from day one, it backed off in a qualifier, my buddy scored the threads a little and I slathered on more lock tight and it works fine. Big companies redesign things all the time when there is a bad perception of the product. They are addressing the issue to cut down on complaints and make it a fool proof item and that is good also, I just dont need one. They could have put the right screws on the truck though Keep up the good work Jammin...your info helps a lot of people. Now give me the scoop on this smart diff...how should I run it!
