I am planning on buying a drop kit for my 96Blazer. The past few weeks I have done some shopping around and have noticed the Belltech equiptment is a lot higher priced than aim and some of the other manufacturing companies. So my question is this, what is worth paying for? Will it really matter if I buy aim drop spindles or Belltech. I can see the difference it coil springs, but am I just throwing money away on the other equiptment?
