Just an update imho. The sets of springs i got must have been poor quality. Two- passenger front and rear have saggedafter 6-12 months. One has broken a center pin. I wheeled it only a couple times. I took my old rc spring and put it back in to replace the really sagged front passenger spring. Also these have 4 leafs, whereas the rc has 5. As far as flex, didnt knotice they flexed great, but i will bend the retainers to try for more flex. Cut one side of the military wrap for more flex.
