Hi Joseph; the sway control won't be impacted using overrated bars like the # BXW4007. You're really not over by too much since they have a tongue weight range. In this case it is 750-1,000 lbs. What you may experience is a rigid or even bouncy ride. If you take your trailer out and it is uncomfortable and noticeable I would swap them out for appropriately weighted bars. If you have the SwayPro you can use the # BXW4006 (rated for 550-750 lbs TW) or for the TrackPro # BLU25FR (600-800 lbs TW).
