With the RC 4" SST kit i installed i had same issue, so i installed the aftermarket bumpers because it was so close, you could have just done that lol.  They sell them on Amazon, called "low profile" upper control arm bump stops.

 

its been so long i forgot even what was there originally.  Was there anything there from the factory on these 2500's?

I removed my bump stops. My upper ball joints were failing after 70k miles and a 2" lift/level with Fox coil overs. No spacers. The fox springs ended up breaking but at the bottom coil so they are still usable while I wait for new Fox 2.5s. My unproven suspicion is that when the suspension had a rapid down travel (driving off a curb or of rocks on trails), the UCAs hit the bump stop and caused a rapid stop. I could feel and hear these in the cab, and they happened often. These rapid stops eventually caused the spring to crack where the coil rests on itself and starts to rest on the lower spring collar.

In any case, Cognito suggested that I remove the stops and that I would not need straps unless the coil overs allowed enough travel that the UCAs hit the coils, which they don't. With the new UCAs, and not having the stops there (with aftermarket coil overs), the truck handles rapid down travel much better. It is smoother and doesn't have the rapid jolt of hitting the stops. 

Of course, your milage (and angles) may vary.

A few hours. I started around 9AM and was getting it aligned at noon. I left the stop it's really not an issue with the new uca.

I have 2014 silverado.  I just did the 3 inches  lift and upgraded the control arms.  And I make the mistake of cutting the bum stop.  And now  the arms is rubbing the struck spring... if i can't  figure out how to fix it I'm thinking about  taking it off.

      I wasn’t commenting on your post. Certainly wasn’t arguing. I was making an observation on my long term experience with supposedly proper length of driving for proper heat cycles. Works for me. Although I have seen water or vapor come out of exhaust when vehicles weren’t run very long and shut off. It’s very humid in the morning. Then hot and humid.

      Not what I said but I can work with it anyway. Complete combustion produces CO2 and H20. When it's cold enough you can 'see' it as water vapor but it is always there and more so the better the tune up. It's physics, not an argument. In a cold motor when the cylinder jacket is below the condensation temperature the water goes to the pan and not the PCV system. Heating the oil moves it from liquid to vapor where it is removed by the PCV system. When and how much depends on temperatures. Of the air, the water and so on. It has little to with the humidity. Water is a combustion product.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      I can only guess as well that something was clicked on that brought you to the half ton choices by accident. By all means try again and chose the 3500 and sort out that its the cab and box configuration you want and choose four wheel drive ( rather obvious to have a transfer case ) and to make sure the dually isn't chosen. I find or at least did a couple of years ago when I was sifting through the options that it would sometimes jump ahead after choosing the series of truck and in this case 3500 and skip some of the other initial configuration choices and have to watch the heading bar and sometimes back up by choosing the first in the series of option break downs. I think sometimes the computer will remember items that were last chosen and skip over the first part. Anyway go through it all and depending on the trim level chosen and I think the LT is one that may fall into that where the option of having the 4 high auto transfer case can be chosen, where as a High Country doesn't show that option as it just comes with the fancier ( not necessarily better though in terms of potential problems ) transfer case but for sure both transfer case choices are equipped with high and low range in the HD truck segment. Like Newdude said who works at a dealership, its the half tons that are the ones that will come with the single speed unless certain options or trim levels are chosen that add the two speed transfer case but as your looking at an HD, you don't have to worry about that hot mess.    One item that at least didn't show up and not sure if it does yet or not in the HD options on the manufactures pubic website is the upfitter in cab switch option if one is desiring that. Unfortunately its not wired in at the factory but the panel with the switches is on the dash but the wiring harness to be installed gets tossed under the rear seat to be installed by whomever after the fact to complete the installation.

      Yesterday we brought home a 6yr  old Havanese dog from a nearby SPCA.  We've had her for 24 hours and we are delighted with how well she is adjusting to her new home.  It  was a huge decision to adopt a dog at this stage in our lives but we believe we made the right choice!   it was reported that her first 6 years were ones of neglect.  I think she's already realizing her life is going to get a whole lot better...  so is ours!
