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 Bilstein 4600 on my GMC 2500HD Duramax and they really improved the ride when towing my 5th wheel. When not towing, they really stiffened up the suspension and created a very rough ride, especially on the beat up roads in CA. If my truck was a daily driver, I'd go back to OEM shocks.
