intriguing, I've so far been running mine for a month now no problems. But of course the dual setup is meant for torque, don't try to push it for top end speed. Based on my running so far, I recommend: modding for greater airflow (cooling fans, vents in the body), staying under a 22/68 gearing and sticking with tires the same size as stock. Also, sooner or later you'll wanna save up for steel center output shafts. It may not have insane power, but its more than enough to destroy COS's. I had 3 spare sets that came with the truck when I first got it, & its already twisted 2.
