Aaron1121,

 

I have the stock ranchos, no lift or spacer in the front on mine now and still get the pogo stick, bucking on concrete highways.

This did not happen with my worn out rear stock ranchos.  So it must be the 5100s I have in the rear having a faster/more responsive rebound

which is probably why these 5100s suck up potholes better than the ranchos.

The lift amount in the front probably has nothing to do with the pogo bucking, compressed spring or not. 

Other than you , I have not come across anyone in these forums having the same problem as us with the 5100 shock.

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

Do you have any other pictures? I will be installing my 5100 next week. Your tire size is what I've been looking at, just not sure yet. Thanks! 

Sure... if you look closely, you can see where the front tire rubbed the inner liner at full lock before I put the new shocks on it. Doesn't rub now, though.

I read through a lot of this topic, but not all.  I see mostly people replacing the Rancho Z71 shocks with the Bilsteins, but I didn't see anyone compare them to the NHT Max Trailering factory shocks.  I have has my '18 for a little more than a week now, and it seems a little bit bouncy.  I have not towed with it yet, but feel it may not be able to control weight all that well.  I dont know, maybe it gets better with some weight.

 

Anyone change out your factory NHT shocks for the 5100's and feel the change was worth it?  Any towing comparisons?

Yes my 2015 is a NHT. Not sure what the difference is on the shocks. I bought it with 19,000 miles and when I would walk around in the bed it had more bounce than I thought it should, very soft. 

I trailered a little better than my 2011 non NHT 6.2 but when I changed the rear shocks to the Bilsteins the bucking and bouncing was improved greatly. When you walk or bounce in the truck bed there's almost no movement... Almost too stiff now maybe.

As for the front the Bilsteins took away the side to side " booble head" action when turning into a Parking lot and maybe a little more control when hitting "whoops" or large bumps. 

Problem is you feel every seam and little bump in the road. 

Bilstein doesn't show a part number last I checked for NHT equiped trucks. I raised the back with a swap of the blocks to get another 2" of height and used shock extensions. 

I'm going to take the Bilsteins in the front down to the first notch and install a zone leveling kit to hopefully smooth out the ride. My theory is that the max lift setting on the NHT gives a harsh ride... More controlled but it beats the truck to death and I don't want more rattles and squeaks.

The description of the NHT package says it has different shock valving, I think everything else is the same (except the rear springs) so I don't see a need for a separate part number. 

 

Did you do any towing with the stock shocks vs the 5100's?  I only have 500 miles on mine and haven't towed yet, but I cant imagine the bouncy feeling getting better with load.  I think the firmer ride would be an OK trade for towing vs the bouncy/bucking feeling.

Last I checked Bilstein says the shocks are for all 1500's except NHT. Not sure why though. Yes I trailered with the stock shocks before switching and the Bilsteins are a big improvement. No sway and less bucking.
I mainly pull a 14' enclosed tool trailer so we're not talking crazy weight. Pulled a trailer type 40' lift but not sure how heavy it was.. But it was a chunk of metal for sure.

Somewhere in this terribly long thread there's some info on which shock is best for NHT trucks. I brought it up at least a year ago but I can't remember which was recommended. I was hoping to get the 6112 if I'm remembering correctly but don't think they'll ever be released. Now I'm thinking about selling the truck so  . . .

I did some more reading through here and saw some posts about NHT owners upgrading to 5100s.  It seems that most people are pleased with the results.  The ones who didn't appeared to have too much sag, stacking lift kits, etc. all things that probably created their own issues. 

 

I also saw old screen shots from web sites saying the 5100's were for all except NHT.  However on TireRack, Amazon, and even Bilstein's own website there is no mention of these not being applicable for NHT equipped trucks.  Perhaps something changed in the shock, or Bilstein has done more testing, but it doesn't appear to be an issue any more.

 

I am going to go ahead and purchase them based on what I have been able to find. I also bought some Firestone Ride-Rite air springs to assist the load in the rear.  I currently tow an 18' open car trailer, but it is all steel.  That with the race car on it, spare tires, fuel is around 7000lbs.  Then I put a bunch of tools, cooler, more fuel, etc in the bed which is probably close to another 1000lbs. 

 

I had a 2000 3/4 ton Yukon before this and it handled the weight no problem, but rode rough and got terrible fuel mileage.  It got to the point I didnt feel safe having the kids in it (old and wearing out) which is why I bought the '18 1500 NHT.  Same tow rating as the Yukon but better ride and mileage.  Th bouncy feeling does not give me confidence towing with any weight.

Amazon Prime is a wonderful thing! Got these yesterday, but don't know how soon my helper and I will be able to install them.

Cool! Always thought the 5100 was a nice looking shock. It's a quick ,easy swap. Did mine in about 10 minds per side.. With less than optimal tools. Rachet broke so I was using wrenches. 

I was going to swap back to my stockers this morning  ( just to compare)but I think they are shot. When I let one fully extend it makes a metallic sound. Thinking about giving Monroe Sensi- Trac a try. I think the Bilsteins are too harsh. I'll see if it's just me this way.

Monroe / Rancho same thing... how long have you had the 5100's they do 'soften' after some miles

Had the Bilsteins on for about 15,000 miles with no noticable softening it breaking in. 

I think the Rancho shocks that come as OEM Z71 are made to GM's specs and not what you'd buy off the shelf. The stock shocks I took off were Tenneco I think.

I'm not seeing the 5100 adjustable shocks for the front of the 2018's  Not on Bilstein website or Summit or others?  Anyone using them to level an '18?  Part number??

      Joke Thread

      By Chuck FB · Posted

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
