one thing to consider when checking chassis uptravel is. I check with the shocks on. And the only reason is because I don't have a way of checking the spring. The springs right to left needs to have the same rate. I know that on xray that the colors denote the spring rate. But I would bet that no 2 springs have the same compression ratio through the entire compression of the spring. So I check up travel with the spring and shocks connected to the arms.
