Can't find specs on the original 1920kv motor that was in your truck. However, if all else is equal that 1920kv motor should develop more torque and handle a heavier vehicle better with larger tires than a 2200kv motor.
E-mail Redcat and ask whether their 1920kv brushless motor can handle 6s with your ESC upgrade. If it can, put the old motor back in on 6s with that heatsink. You may be surprised at the performance. If it runs well, just sell the 2200kv motor.
Later,

I'm running two 3s 5000 mAh/100C LiPos in series, but the ESC is going into thermal protection shutoff (I have it set at 105C/221F) within two-three minutes of driving it around the yard.
My question is, is using 100C LiPo's the reason for the excessive heat, or because the weight of the vehicle.
The manual states that if the vehicle is above 7KG, to use the Max6 ESC. It's a little above that weight, but didn't think it mattered that much, to where I can't play with it for more than a few minutes.
