We carry all you need to handle your hitch and trailer weight distribution requirements.
Why should you be concerned about weight distribution? When towing a heavy load with a standard ballmount, the majority of the weight lands on the tongue of the trailer and eventually the towing vehicle; this weight is your "tongue weight". Too much tongue weight in relation to gross trailer weight can cause the back of the vehicle to lower and the front end to rise.
If your vehicle is in this position, then it requires a weight distribution hitch or you will lose braking traction and steering control and subsequently, increase trailer sway.
