Ok, I have the 2.5" coil lift with shock extensions from TF. I would like to install the 1" TF coil retainer in the back so I can get a small amount if extra lift cause i like that look and plan on swapping the shocks out later on. The stock coil pad is 1/2" thick, if i just use the 1" coil retainer it's only a net gain of 1/2" which is all I want. Question is, do i need to get an adjustable track bar in the back because of the added 1/2" or will i be fine with just the bracket that came with the kit that drops the stock track bar? Hope that makes sense .

 

You will be fine without the trackbar.
