RE HD track bar

I have 5.5" to 6" of lift with the RE 4.5" kit and spacers I was wondering If the RE hd track bar is really needed. I have had the current set up for about 3 years and have noticed that every once in a while (usually when I am playing in the mud or snow) the stock TB mount creeks when I turn to the left. A little shot of WD 40 and its good until the next wet one. I always tighten the mount and make sure it is in good shape but I am wondering if it is worth forking out the $220.00 (new tb and bracket) or is there a way to beef up the current re bar that I have and the stock mount.

thanks
Jeff
