Simplest mod I have ever done, less than 30 minutes including cleanup. I just put timbrens on my 2014 2500. looking at the clearance with the truck bed empty there is 1/2" clearance on the rear of the timbren and 1/4" on the front side. It doesn't look like it will hit the plate on the axel square when weight is put on the bed of the truck, should it be that way. One of the timbren brackets was marked left with an arrow pointing and the word front printed with the arrow. I assume that bracket should be installed on the drivers side with the arrow pointing towards the front of the truck. Any input would be helpful.
