This doesn't look like a GM truck. Not needed on a HD truck

Not true! I have been runing them since 2006 F250!

suspension component that works as a sway bar, a traction bar, and a helper spring points directly to the RoadActive Suspension (RAS) kit.

I've got them and I think they work pretty decent, what I noticed right away is it took some of the bounce out of the rear end when going across washboard roads and railroad tracks when not towing. When towing my 5th wheel it seems to make the truck more stable.

Which ones did you get the HD or MD?

 

After driving back from South Carolina this morning, I can confidently say the unloaded ride is considerably better with the RAS installed than it was without it. The truck feels more stable, smoother over bumps, and overall more controlled. I wasn't expecting such a noticeable difference when unloaded, but so far I'm very impressed with the improvement.

Since the ride appears better, does that mean they are adjusted up so that it lifted the truck up some and therefore taking some of the workload off of the main spring pack and also preventing the main pack from landing down onto the bottom overload spring ?. A friend of mine put them on his half ton chev for towing a bumper pull RV as the half ton has rather sad springs to begin with and carrying much weight isn't what they were made for ... ride is the half tons bonus though because of that. 

 

I imagine it probably states in the instructions or application that its not meant to fit the 1 ton or I assume it would not fit as the overload leafs would be in the way and perhaps even the frame pad for that matter when the suspension would get stroked out with weight or a big bump.

By rights these trucks should come from the factory or at least have a factory optional anti sway bar for towing high trailers and certainly slide in campers. GM always used to have their trucks fitted with rear sway bars if optioned properly but for some odd reason don't do that anymore. Certainly a sway bar would help that issue a lot, not the ride though but the leaning/control.

Most 1 ton trucks come with the factory overload spring, which need to be removed for installation of RoadActive Suspension. Removing the overload allows proper fitment and ensures the system works as intended. The RAS® Mega-Duty kit will reduce squat and provide significant improvement vs the factory overload spring.

Yes I have is set with the 1mm disk (Minumim Tension), for spring spacing and I raised my truck in the rear 1.5". You can go 2mm  and I think 3mm if you need.Minimum. We are on our way to TN from GA.. My wife is driving and stated she cannot believe  and   stated she can not belive the difference.

Good question, I don't remember for sure but I believe it was the HD. I will check and get back to you.

      Some Assembly is Required

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
