For the Pro Series RB2 system and its head, # 58333, there are different spring bars you could use. You need to go by the total tongue weight of the set up. This is the tongue weight of the trailer when loaded and ready to tow plus the weight of anything loaded behind the rear axle of the vehicle.

For a 3500 pound trailer and a tongue weight of 10 to 15 percent you are looking at 350 to 525 pounds. You can use Item # RP58114 for 1 round bar with the cam end. These are rated for a tongue weights between 400 and 800 pounds and should work fine if your trailer is a little under. Weight could be added to the rear of the vehicle behind the rear axle or near the front of the trailer to increase the tongue weight if necessary. If you also need chains and hardware for your new bars I would recommend Reese's Replacement Weight Distribution Chain Kit Item # 3216.
