one of the weaknesses in the early challengers was the air inflated front idlers.they couldn't be inflated high enough to prevent the driver from spinning inside the tracks.i'm not sure which revised model [b,c,d,e ] those were changed to a solid idler.believe me I've first hand experience with the drivers spinning inside the tracks especially in soupy clay conditions.
