The Heavy Duty Round Bar weight distribution system was developed by Reese and is now carried by Draw-Tite and Hidden Hitch. The system uses spring bars that are tapered like the trunnion bars to provide excellent flex and even includes the serrated washer design to make dialing in the system a breeze. The only difference is in weight capacity. Where the trunnion style systems are rated for up to 12,000 lbs. GTW, the heavy duty round bar tops out at 10,000 lbs. The system will work with friction sway controls while the spring bars also include the cams to work with the Dual Cam system.
