TV is a stock 2005 2500 HD GMC with D/A. Tow a 29 ft. 5300 lb. dry TT. Looks like I can use either Bilstein 4600 or 5100 shocks. Any suggestion as to which one I should use for best tow and ride? ...
I put the Rancho adjustable shock on my Excursion. We don't get a lot of snow and salt use, but it wasn't a season or two that they were no longer adjustable. No matter how much WD-40 was used. I was not impressed with them the entire time I had them. The next truck I put the Bilstein 5100 series on and it was noticeably better all the time. Towing and not towing. My new truck had less than 3500 miles when I put Bilstein 5100's on it.
