ESPO or Hotchkis Rear Leaf Springs

IMO buy espo if you only want the springs. Buy Hotchkiss if you was the TVS. the Hotchkiss stuff is tuned to work as a whole as a balanced system and that is where I think the $$ is worth it. If you aren't building a hard-core canyon carver and don't need that super handling then you can't beat the bang for the buck quality of ESPO
