Excuse me if this is a dumb question, but I couldn’t find the answer anywhere, and CST never responded to my email.

 

Since the CST lift (full bracket lift) requires the cutting out and removal of the bump stops; what stops downward suspension travel, say if your front end got air :D?

 

The bump stop remains intact and useable with the spindle lifts (bds zone etc), so its a non issue for those lifts....

 

right now as i *believe/guess* the shocks would stop downward travel? If so is this really ok?

The new brackets have stops that limit down travel .

The new kit does not include straps like some Baja kits do. 

Looking at pics from their website (below) the new brackets do not appear to have new bump stops. There is only a thin line of metal below to bottom of the UCA. This line looks too low and close to the frame to have any impact on the UCAs movement. Stock bump stops are much thicker in this area too.

Correct, in addition to the stage1 kit, I’ve also got the CST front 2.5 coil overs and rear piggy back 2.0’s. I’ve not jumped anything major but have jumped off highways at approximately 40mph (with stock UCA’s) and the response of the CST Suspension was excellent, almost felt like it was gliding and never even felt any bottoming out.

can you take take a pic of your CST stops please? The pic posted above was taken from CSTs website and it does not appear there are any stops. I’m not worried about bottoming out as that’s compression (upward travel) of the suspension. I am curious what stops the wheel and control arms from going down when the wheel is in the air.

Check out these pics and the lack of bump stops for the CST brackets vs the stock ones. The CST only has the think price of metal that is low and recessed, it appears to be there for structural support/boxing of the bracket. It does not appear to be a stop.

I’m not trying to bash the CST lift. I think it’s the best lift out there for what I’m looking for in a left kit, but this is holding me up from buying one in the future (unless it’s not a problem).

I’m not even sure bump stops are what stops downward wheel travel. It may be the shocks themselves for all I know. This is just the only thing that gives me pause on going with the CST lift until someone can explain what stops downward suspension travel.  I really wish CST would have written me back.

It’s IMHO The best you can buy, it’s a superior quality lift that far exceeds in craftsmanship which is second to none. Own one and you’ll see why.

In addition to the design of the kit which limits any bottoming out, the shocks also have built in bump stops too. Btw, calling CST is the best way to get your question answered.

There definitely should be some kind if physical/mechanical stop to upward and downward travel. The struts should not be it.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.

      OCI, not when but why?

      I put the prof up. If you read what I posted. You can see that housing, cars and income are in line with the era we were talking about. It’s harder in some places easier in others. Let’s agree to disagree and put this back on track, OK? We both are pretty stubborn and hard headed. But I bring receipts. If you wish I will not respond to you in the future.

      Lets see if I can sum up two pages of nothing useful.    You want to refute your own governments data of the "Purchasing Power" Index FOR THE ENTIRE USA and its territories replacing it with the experience of a single family and its business and label that reality?  Then pound on that for a week hoping it will find traction?    Stan, I've told you several times. I don't do irrational. There are more people in the USA than your family.    I'm pretty sure this tread is so blown up. I'll give you a few days or months if need be to post yourself silent then I'll see if I can find enough parts of the train to reassemble it.

      VSE CCV Bypass - Anyone have this installed in their L5P?

      By asilverblazer · Posted

      Facebook groups hate VSE, poor customer service; their responses to criticisms are pretty poor for a reputable company. I'm not a customer, haven't bought anything from them, but how they handle themselves on social media is a definite "No" for me.

      Transmission Woes :-(

      By asilverblazer · Posted

      $10,000 for a transmission?   Pretty sure I could buy all the parts, tools, and education to rebuild it myself for a quarter of that amount.   or swap it out with a new one...
