Do you notice a rougher ride in the front due to the angles that the cranked up torsion bars put the suspension arms into, typically doing that to independent suspension trucks makes it noticeably rougher riding. Obviously the pressures you carry in your tires will certainly make a difference as well one way or the other. By the way how has the L8T engine done for you so far, any issues and I am guessing the fuel mileage is nothing great due to these trucks size and weight, never mind your raised height.
