I just converted my Typhon to a Kraton, the Kraton chassis, front arms, rear lower arm and upper link, wheel axles, rear cv shaft from trans to rear end, steering links, body mounts, rear shocks(old rear shocks get moved to the front)are all longer...and last wing, tires and wheels, and body. if you leave the chassis as the typhon but change the arms and such it becomes the outcast size. Hope that helps!
