I know and that has me conserened. I took the CJ front springs out of the rear and moved the Marlin 3" front springs to the back. I installed Marlin 4" springs in the front in place of the 3" springs with a leaf removed. This is much stiffer than before and is causing less flex. I just don't have enough weight to bend the springs. I plan to remove a leaf from both front and rear to make them softer. I had 24" before and now I only have 20". I also have an idea brewing with air shocks. I will wait to see what happens after removing the leafs.
Removing the leafs should work good, the Mammoth cant weigh more that 3000lbs.
