I did look at RockAuto they don't stock this part.

I ordered from GM parts direct but they wants three weeks to deliver it which seems absurd, they did offer 3 day delivery but wanted $140.00 for shipping which is ridiculous.

Ah, you must have something else then a 1500. Mine were in stock.

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

I ordered a pair of the 5100s for the rear yesterday from amazon, can't wait to see the improvement towing.

Alright guys, got my 5100s installed this weekend and had a chance to put about 20 miles on them so far. I'll update in a month or so when I get some more (my DD is a company vehicle). My truck is 2018 Silverado Z71 crew, 800 miles and  275/65r18 Duratrac tires- P rated as I wanted to avoid LT tires.  I live in MN so the roads are much rougher than what you guys get down south due to the hot and humid summers and freezing winters. I was very concerned with ride quality. 

 

Because my truck had a lot less rake than what people report theirs had, 2.25", I went with the 3rd setting (1.25" lift) and replaced the rear 1.25" block with a 2" flat block, no taper. This gave me a 1 3/8" lift up front, 3/4" out back.  End result is I maintained 1 5/8" rake.  For me, this is the perfect amount of rake as I don't like the level look.  I've also read the 2017-2018s use stamped steel arms and we can't lift as high without replacing arms than you 2014-early 2017 guys.  I wanted to stay under 1.5"

 

A lot of guys are swapping out their shocks at 30-60k miles, so it might not be a real fair comparison to new Bilsteins.  I also saw some complaints about a rough ride and am happy to report the ride is no harsher than basically new Ranchos, I'd say it's actually a tad bit softer on small cracks.  It doesn't have the long lasting shudder on big bumps either. I have not driven on the highway yet to see if the wallowing is better/fixed. 

 

I didn't have any highway vibration before, but I did have some in 1st gear on hard acceleration.  Right when you hit the gas and some near the end of 1st.  I didn't notice any in 2nd gear on up.  The dealer said they noticed it when I brought it in but it's normal and they all do it, no tsb on the issue.  We know that's false and there is a tsb dealing with driveline angles.  Well it appears the small front and rear lift brought those levels more inline as I didn't notice any vibration on either hard launches I did today.  

 

So far I really like them.  Hope to feel that way as I get some more miles on them.  I really disliked my Ranchos and was surprised how much I didn't care for the ride on a new vehicle.

Congrats, they’ll start softening up a bit more as time and usage goes by.

I have a 2014 silverado cc and have a 2” zone lift in it. When it was installed I was told by the installers that the rear shocks were now too short. I’m looking at the 5100s and after reading I still am not sure..... are the rear 5100s longer and will help with this?

5100's will accommodate up to 1" over in the rear.

I hate to report my Bilsteins are causing a problem.

I can no longer do burn outs and get sideways with no problem. It's like the k2s are stuck to the ground. This really sucks lol! To me these struts and shocks provide a sporty ride quality like a Camaro. I have mine at the highest setting, that being said the ride is a bit stiff. I'm used to it though as I've used the 4500s in the past and know these will keep big tires and wheels planted. I wouldn't buy these for comfort by any means.

The more I drive it, I notice they are a tad firm. Really it's on the highway the truck still feels a little bouncy, especially on concrete.  I'd have gone with the 6112 if they were available as they're supposed to ride better.  They have been coming soon for years though.

That’s cause they’re performance shocks, mine rode the same way and softened up after a month or two. The 6112’s are not made as well as CST, FOX, KING or ICON. In my opinion, after comparing Bilsteins to real performance Shocks, Bilsteins are beginner, entry level shocks. I found Bilsteins, their resi’s have molded plastic caps on the ends, very cheesy.

Remember, Bilsteins are not necessarily valved as the upper name brands, they need breaking in.

Btw, the 6112’s are identical to the 5100’s only they have knock-off resi’s lol

Actually they use their own spring, which is longer and a different spring rate than the oem unit.  Due to it being longer it doesn't have to preload the OEM spring, it actually lowers the spring perch for a lifted spring height.  

 

Additionally the strut uses a larger diameter Piston and is valved completely differently due to it using different spring rate/length.  

 

Basically, it's called completely different.  It doesn't use a remote resevior either.  

 

The 5160 is closer to what you describe but has different compression and rebound rates than the regular 5100.

You’re correct, confused the two.

Btw, I ran over a few speed bumps pretty hard in order to breakin my Bilstein 5100’s. I even put on brand new 5100’s as temporary shocks after the lift in order to have something to compare to. Once I switched and went with CST Coilovers, I new I had a winner with the CST. CST actually runs and tests them on the vehicles they sell them to be installed on, quite possibly the main reason they’re so far higher quality. Bilsteins are far better shocks than stock, that’s for sure.

Which CST kit do you have?  I've also looked into HaloLift Boss, at $899 for the fronts.   I think the Bilstein 6112s are $699 for other vehicles and imagine they will be the same for GM 1500s. 

 

Is your ride bouncy on the freeway, especially concrete ones with expansion joints?  Was it before?

      There's some truth to the above, but also, she's selling fullsize trucks and bread/butter CUV's like hotcakes, meanwhile, extracting GM's pickups from the deep discounting sales game.   GM's stock has held its own during her tenure, and the more recent buybacks are delivering cash back to investors and signal confidence in their direction forward. Even with the EV losses.   GM is an example of a modern publicly traded company. The #1 goal of any publicly traded company is to deliver the most value possible to shareholders. Despite being a car company, building the best car isn't GM's path to delivering maximum shareholder value.   McDonalds doesn't make the best burger, or the best coffee.   I've mentioned in another thread, I really don't / won't ever understand Cadillac or Buick in a modern context. Both brands are completely dead to me. I'll cede that the Escalade is a nice SUV, but the brand and nameplate mean nothing to me, and GM will never persuade me to pay north of $170k for a gussied-up Tahoe or Burb. Other people don't mind doing that and that's their purview.   The C8 shares absolutely nothing in common with any other current Chevrolet or Corvette on the market. Since its introduction 8 years ago, it's developed quite the following. It did what other Corvettes couldn't do: reduce the average age of its buyer. GM has something there, and I see them investing in the car. They'd better not mess that up.   We've successfully derailed Grumpy's thread again, but I think this one is meant to be more of a random thought thread so a little wandering is probably OK.

      Sliding doors ftw   Also, Sienna ftw as well.  The in-laws got a 2024-2025 recently when their 2019 sienna was totaled due to a deer back in June.  They've been getting 38-40mpg on the 65mph highway they live on.

      07 yukon xl 6.2 stalls at hot idle and wont restart

      Forgot to mention that this started after changing the oil I use mobile 1 full syn with mobile one filter but I did add pro lube additive and was the first time doing so and is making me wonder just can't see why that would matter

      07 yukon xl 6.2 stalls at hot idle and wont restart

      By xdieselmechanic · Posted

      I apologize for long post put going to try to explain everything. Parts replaced so far: Cam sensor Crank sensor Cam phaser valve Cam phaser solenoid Fuel pump Maf 1 injector Pcm Pdm   So about 2 weeks ago coming off the highway my 2007 yukon xl with the 6.2 stalled and would restart. Had unit towed back to house and I messed around with relays and unit started. Drove it the next day and same thing. Had it towed again. Scanned unit and had code p0300 with misfire data showing mainly cylinder 7 but I know that won't cause a no start. Measure fuel pressure and found only 42 psi replaced pump to have unit stall again and not restart. This time I stayed on back roads and just waited for it to restart about 30 to 60 min. During this time I found I have no injector pulse but have good power at injectors. Started unplugging 1 injector at a time and found when unplugging cylinder 7 pulse came back so i changed injecto and same issue. Turns out unit just happen to ready to start at that time. Scanned into unit and found no reason for the pcm to take away injector pulse so I replaced the pcm and same issue. I figured timing sesnor controlled the injector pulse so I replaced both sensors and while I had the water pump of i replaced the vvt components while i was in there. Read multiple people have luck chaging the maf for this issue so I changed it. Unit still stalls to this day and loses injector pulse on the ground side when it does. Have noticed watching the live data the pcm is request injectors to fire via injector pwm value. I have redone the ground wires at the left bottom of the block knowing this was the ground location for the pcm but still no luck. I am a mechanic by trade but this is having me pull my hair out. If anyone has something to have me check I will gladly im not much of a parts thrower but im about to load the cannon

      auto mechanical driver's door unlock without pressing button? [2026 Silv. 1500 WT 4WD RC SB 2.7L]

      By newdude · Posted

      Actually.  Wait.   I just re-read your original post.  Are you talking from INSIDE the truck you have to hit unlock?  Or from the key fob?  I had assumed from the key fob.   IF you are talking the inside unlock button, I assume you are shifting to park and its not unlocking the doors?  If so, that is changed via the settings page in the radio.  Go to SETTINGS, then VEHICLE and then it should be under LOCKS or DOOR LOCKS or something like that.
