This a a complete setup with all the hardware and instruction to hook it up to your trailer! Very similar to this one Strait-Line Weight Distribution System w Sway Control - Trunnion Bar - 10,000 lbs GTW, 800 lbs TW Reese Weight Distribution RP66083 (https://www.etrailer.com/Weight-Distribution/Reese/RP66083.html) My set up is 10,000 trailer and 750 hitch but the one above is the closest I could find at etrailer. Same dual cam high-performance sway control. They are asking $541.40 shipped, I am asking $350 shipped! (you know if you live in albany or salem that is, other wise we meet up half way or something) I live in albany. Any questions just ask!
