I bought a 2006 double cab, TRD Sport in August with a long bed. I already put 24,000 miles on it and I am starting to think about what shocks I am going to put on it. I don't drive it off road and I am looking into Bilstein HD or 5100 because I want to improve the handling. I had the HDs on my 98' and they rode extremely harsh, of course the springs were not progressive either like my current truck. I called Bilstein and asked them about the HD for my truck and they said that they are not as harsh as the old HD. Anyone try HDs on their truck yet? I thought the 5100 might perhaps provide a little bit of a better ride, but my truck is not lifted and the tech at Bilstein told me that the HD matched the stock spring rate better than the 5100s. Ideas? Thanks.
