My UE truck has 8 Kyosho rear buggy shocks. They're really long, but the springs are too soft for an all aluminum truck. A set of eight Special II springs would cost $50, and are only 'medium'. The UEs are lots better. You only need 4, and spring sets are only $17. If you really want regular buggy springs, I'll sell you mine. I was thinking the crawler guys might be interested.
