This sled has a Fuji 650cc tripple F/A that made 105hp. These sleds were designed by Indy racer Bobby Unser. This indepent front suspension used a trailing arm, shock, and upper and lower controll arms. This IFS was the predecessor of all trailing arm front suspensions. If you ever get the chance to see one, you can see just how far ahead Chaparral was from all other makes.
