The reason for the thicker fluid in the front is to settle down the front end. If you have driven the truck before, you would know what I'm talking about. This tuck is very responsive to steering inputs. The thicker fluid tames it down a bit. But dont worry, the truck still has plenty of steering left. Im running 30k front and 7k in the rear, and still have to dial my dual rate on my transmitter to 75%
