The lxm766 is for your clutch bell. This is the part that most RTR kits will put a poly/plastic part in. If you melted the clutch, the plastic part will most likely warpped. Having this type of clutch will get your playing around more fun.
Sometimes, clutch is the most overlooked part of tuning a car. This is the clutch I used before prior to me going to centax.
