I have a 15 F350 LWB with a Pure Perf. 6" suspension from front to back w Fox 2.5 adj. shocks. When I hit the brakes I hear a clicking noise in the front end...I have upgraded the track bar..but they have to keep cranking down on that piece above, or connected too....whats the piece called and how do I go about upgrading this with the best part or parts. Thank You. Jeff
