I just wanted everyone to know that metco did have a problem with some leafsprings that split just above the axle. I recently purchased a set and did notice the difference in weight, I also picked up quarter mile times by switching these out. The bad news was, one day I walked outside and my truck had collapsed in the rear due to the springs. I was beside myself thinking metco wouldnt cover these... Guess what, I talked with Aaron and his dad, and the reply was "No Problem, New set is on the way".. Thats what Im talking about, a company that takes care of its customers no questions asked. Could this be true.. Now these new springs have been corrected and everyone who has them should be real happy. THANKS AARON, Jeff in Augusta.
