WEIGHT DISTRUBUTION - If your trailer weighs more than 5,000 lbs. you may need to add a weight distribution system to your hitch to achieve the desired towing capacity. Weight distribution uses spring bars to absorb weight and keep everthing nice and level. Spay control bars are also available for added stability and control. If you don't see the hitch or towing accessory that you are looking for, give us a call toll free at 1-866-820-2153.
