I had the tapered block. Made the truck vibrate at 70+ highway speeds. These are flat. Couple things to note on the brand that I am not happy with. The dowels you see on these blocks are to long. They don't let the block sit flush on the rearend pads. So I had to take my grinder and shave some off so the fit flush. Also the holes on the other side to align them on the leaf springs are to small of a diameter so I had to enlarge them so the spring dowel would fit inside. So on that I'm not happy I needed to " fix " these mistakes. My motofab 2 inch blacks fit perfect minus the taper that made the drive line vibration. And yes I know it was those as I didn't vibrate before the motofab blocks. Now onto the shock extenders there. Well on there site they say for a 2015 1500, but when you re I've the install instructions they state for ford super duty or Chevy gmc HD series. Tried to install them and no go. So I will not be doing anything with supreme suspension again. Gonna call them tomorrow about the extended and let them know customers will have to fix their work on the blocks. I'll be hitting the highway tomorrow so I'll tell if these fixed the vib.

My readylift blocks are tapered and they never caused a driveline vibration.

Weird. Maybe I have that vibration that everyone else has said they had. Its not so much a vib but like a harmonic resonance I guess. Just took it down the hiway and its still there. No clue what is doing it

      Towing In Loose Gravel

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?

      The use of absolutes like "always" to describe gear selection, and giving free advice at a boat ramp sounds like a recipe for disaster. It's a boat ramp, not a farm, for starters.   IMO gear selection should depend on the obstacle. If low range is working and this is a slower speed, controlled ordeal, I'd keep using that.

      I had a boat for many years, never had a problem even with a 2 wheel drive 93 Silvy for 20 years. Good tires, proper use of the gas pedal worked.

      I read through that and I won't lie, my eyes rolled at some of the quirks about how it can turn off the trailer braking for example but I can see how it could help control or even up the torque applied to the ground with each wheel in a boat ramp scenario. But of course what it can't do is increase the torque to the wheels if the need is there as it ends up being like driving the four wheel drive version of a two wheel drive ( high range that is ). So far the neighbor that ended up with the 3.0 duramax with the max tow package which meant the 3.73 gears and high range only, I think its been doing ok for what he has been towing but doubt he ventures off into the soft stuff with his holiday trailer. He may have towed his dads river boat locally with it ( he always used his 6.6 duramax before ), I'll have to ask him sometime if he got into a lack of power to the wheels situation as after all that engine produces a lot of torque at low speed once the turbo winds out a bit and I think it has the 10 speed and if so they have a pretty good first gear ratio at 4.70 I see which is vastly better than the 3 or four speed overdrive models of years ago.
