biggest problem with the thunder quake is the axles are too weak for the big tires and the spur gear is too thin ... but at www.extremercparts.com they have much better quality parts for this monster of a truck ... also they will be selling thicker spur gears after the 1st of the year ... other than that it is a nice truck ... a little weak in the low end with the stock engine ... but that can be upgraded easily ... i have had my tq for over a year now and love it ... slowly upgrading parts here and there ... but that goes with every truck ... i think for the most part it is a very well built truck ...
