If you understand the basic function of a weight distribution system then you understand the function is to take weight off the rear axle and distribute it onto the front axle of the tow vehicle. The only way to do this is with pretty serious leverage. When you see those large forged spring bars flexing and putting weight onto the front axle you see what kind of force it takes. Those 2 little springs may help with sway control since its trying to keep things straight but will be very ineffective in actually transferring weight to the front of the truck. Pretty hokie set up if you are going to call it a weight distribution set up. That 4 or 5 inches of leverage won't do a thing on a heavier trailer and doubt it would do much on a light trailer. Save your money and get a Reese,a Curt or a 4way system.
