Installed everything myself. These fronts were a b***h. Removed UCA, steering, sway bar, just to fit. Ball Joint was a pain to separate from the knuckle. But it's beautiful.

I put the bilstein 5100s on the rear of my 14 High Country with a new 2" block a few weeks ago. Ride is unbelievable compared to stock. Liked it so much I got the adjustable 5100s for my front, remove

Hello, I'm not new to the forum but I just joined and figured I'd contribute to the community.   2016 Silverado 1500 "Z71" removed rancho's and swapped with Bilstein 5100's all around. So after d

I just got done with installing my 6112's on my 2014 GMC Sierra Crew Cab.  Reading some install guides on here really helped, along with printing some Chilton Repair guide torque specs that I got from

Your truck looks great.

 

When we removed the stock fronts and installed the 6112 on the highest setting on my '15 Sierra NHT, we only had to disconnect the swaybar on both sides. It was surprisingly easy. I wonder what the differences are?

On my 14 4x4 WT I only disconnected the sway bar and lifted the strut in place with a jack.

Stock height or lifted?

Maybe get some wheel spacers either way to prevent the rubbin.

What part is it rubbing on, UCA or liner?

Sorry, forgot to mention some of those specs. 

I would like to stay away from spacers as much as possible.

Ive been reading a few pages of replies and questions. But I my question is I have a 15 Silverado crew cab midnight edt. 6.2 ltz z71. And I'm going for the lower sport truck look. I removed the blocks out of the rear and stock up front. Will the 5100 still accept the lower height in the rear or should I use a drop shock in the rear and regular 5100 up front?? 

Thanks

Should accept the removed block fine. The rears don't provide any additional lift.

I haven't done anything else to figure out my odd measurements but after doing more driving, I think the ride is getting even better. I noticed that my body subconsciously tenses up when it knows I'm about to drive over bumps that I hit everyday and the hits just don't seem as bad as they once did. I still have less than 200 miles on the 6112/5160 setup and I'm more pleased everyday.

 

I think I read somewhere that the 6112 springs were softer than the OEM springs and I believe it. The truck does seem to lean slightly more in turns but it isn't bad. The truck now rides like I think a 4x4 truck that had a nearly $60k MSRP should ride. Money well spent. 

This is interesting to me. The 6112 uses a 750lb spring which, imo sounds pretty high. A lot of coilovers use 650-700. Someone posted before that own is 745. 

 

I have the 5100s and don't love them, it's pretty firm. You say the 6112s feel softer than OEM?  Do you have the NHT / max tow package?

I was talking to my friend about this after I posted the response you quoted and he pointed out that maybe the side to side roll that I think are softer front springs could be the result of higher ride height, I'm not sure. Another element that could be fooling me is that the spring and shock are matched better than OEM which achieves a better ride quality even if stiffer sprung. What I am sure of is that the ride is much better on our far from perfect roads, I've noticed that I drive a lot faster around town and now I need to be more conscious of it where before my truck would be uncomfortable and even unsafe in a few spots to drive even at the speed limit. I still only have a few hundred miles on it but the ride quality just seems to keep improving.

 

My truck does have the NHT package.

It's also possible your trucks original springs are firmer than typical 1500 GM trucks, so maybe they are softer.  I have a Z71 which has a firmer ride than regular but I don't believe as firm as a NHT truck. I know your front sway bar is thicker too. 

 

I just switched from a 275/60r20 to a 285/70r17.  It's supposed to be 32.8", but it's more like 32.3 and my 275/60r20 was about 32.8.  With 2.5" more rubber (same model tire) it got ride of the harshness I had. 

 

I was hoping for more change and at first it seemed very slight.  After putting a couple hundred miles on it, I'm good with the ride for now.  I went from a harsh riding truck to a firm riding truck. 

 

If positive reviews keep coming in on the 6112, especially in comparison to the 5100s I may consider them next year.  I just wish Bilstein went with a softer spring than 750lbs.

Well, my 5100s have arrived and I was planning to tackle the install this weekend with a buddy.  He used to be an Infiniti tech so he's got access to a wall-mounted compressor.  My plan is to remove the existing 2.25" level kit, set the 5100s on the highest setting and re-use the 3/8" spacer under the 5100 to get back to 2.2" of level.

 

I'm doing this because my truck's had a suspension-related rattle for some time now and has recently started rattling and creaking very badly when the suspension flexes. When we rock the truck side to side, we feel the vibrations from the creak in the shock/spring assembly much more than anywhere else.  So, I am about 60% sure that the problem is in that assembly.  We can also see the top of the shock move in the mount ever so slightly (a few mm, nothing more) when viewed from above.  It's almost like a bushing is failing but I don't know if it's normal or not.  I can't get a clear view of the other side..  The motion I'm talking about is in the center section of part 8 in the diagram.  We'll check the ball joints as well just in case, but I thought 2.25" was supposed to be safe on those. 

 

Should I hold off on the replacement until I can get new top mounts in?  I'd hate to tear it all apart to have to wait a week for parts.  I daily the truck, but I do have alternate vehicles I can use.  If it is the ball joints, should I replace the UCAs with the RC ones or just change out the ball joints with OEM or MOOG units?

UCA replacement would come down to how bumpy the roads are you travel on. Your old ball joint could be messed up from the lift. Get an upgraded one with more travel or switch to uniball if you live where road salt and crap won't harm it.

I would personally leave out the 3/8 spacer. 5100 at max are as high as you should probably go w/o upgrading uca. Plus, it will effect the ride in a negative way.

Definitely get some new top hats(upper strut mounts) prior to assembly just in case. They're not that expensive and you could always return them if old ones are still good. Get oem ones.

Well, I live on a dirt road, so yeah bumps are very common for me.

 

I thought I remembered reading that 2.25 was safe for the ball joints but I guess not.  I wasn't aware of upgraded ball joints other than the UCAs that rough country offers.  I don't think I need to go to a uniball.  That seems a bit extreme, but what do I know.

Yeah, upgrading uca would give you better ball joint than factory. Think they also make ball joint upgrades for stock uca that allow more movement.

      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.

      $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...
