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.

      OCI, not when but why?

      By Chuck FB · Posted

      That's interesting, I assume that would add to the cost of the oil but also I was forgetting to bring up the issue of the low tension rings allowing more oil past which in turn forces the cats to have more oil additives pass through them that wouldn't otherwise so they are creating that problem and of course its all in the name of fuel economy. Mind you the other issue would be the lack of additives that fight the formation of carbon within the piston ring grooves which turn the engine into an oil burner and with in this GM forums case is your average off the shelf Dexos licensed oil, meanwhile the other off the shelf oil being Valvoline's R&P isn't licensed and the only one that is which is that certain Mobil oil that came out recently ( its not even being marketed in Canada ) and only a fraction of vehicle owners are going to be using it out of all the other oils on the shelf or the quickie lube bay that meet the Dexos spec by way of actual licensing.    Also I suspect that its an easy excuse to pool the non turbo DI engines in with the turbo DI engines and design the oil to not have LSPI issues in the most demanding engines and short change the naturally aspirated DI by not offering a higher concentration of additive package they could handle and still not be at risk of LSPI.    I wonder if Amsoil flipped the switch just lately and did whatever packaging designation at the same time as I wonder what oil formulation I would have bought in May, of course I don't know when it was packaged at the factory vs how long it was in storage at the Edmonton warehouse. I know its been said at least in the past that the big players switch over to a reformulated oil but the packaging has not changed until they make that move as well so there is that cross over time where its a new formulation in a predated formula marked package.

      Hmm. A real reason to not just use the odometer to determine OCI?

      Sad thing is that this doesn't have to be the case. LSPI can be solved without a reduction in TBN. Swap Ca for Mg.  Cats are not a issue if the OEM can get a ring and valve guide seal even at SN levels of SAPS. Dizzy is purring like a kitten with a bowl of warm milk. 200K of Full SAPS oil and zero detonation issues and nice a clean inside and out. This shouldn't be an issue. It isn't 1920.    Tell ya what AMSOIL SS is excellent at, internal cleanliness. The new formula is even a step up from their already outstanding cleanliness levels. Can't say the OEM offering is quite that clean. There marketing suggest the SS is cleaner.     That is the only defense with at shelf oil. Nothing wrong with them if you ignore the marketing and OEM 'recommended' OCI and use a thimble full of common sense. 😉 You go sir.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.
