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 used this thread for guidance with the same question. 2 nights ago I ordered Bilstein 4600's for my stock 2007 GM D/A dually.
From what I've read in the above linked thread, 4600 and 5100 are identical in build and function, with the exception of the 5100s being suited for a stock to 2 inch lift.
