@JR09country I will sure give feedback on this thread. I am not expecting King/Fox 2.5 performance although that’s what I’d really like. I just can’t handle the bouncy floaty ride of these ranchos esp

I think you will be happy. I did the same set-up, except with a 1" block.

yeah I tow stuff and there’s nothing worse than running around nose in the air and ass end sagging. Especially on mountain roads where the headlights become ineffective. I only have 1” difference between the front and back fenders in stock form and if I stand in the bed the rear is lower than the front.. that’s no bueno.

I am new to the site but have been lurking for a while.

 

I see that Bilstein offers two different part numbers of the 6112 for the T1 Silverado, 47-293557 for non-Trail Boss and 47-309524 for the Trail Boss.

 

Does anyone know if the Trail Boss version is longer to begin with or if it just has higher c-clip ? Do they use the same spring rate? Does anyone know why it doesn't show as being compatible with the Sierra AT4 Duramax?

 

I have a 2020 RST Duramax and am trying to lift 2.5-3" in the front and thought the Trail Boss 6112 on the middle clip would be ideal if there is no obvious compatibility issue.

 

Thanks in advance

Great dampers. They really soak up bumps and take all mush out of the ride. Sucks they are on back order.

 

I set the 6112s on slot 2 which is .40”

 

Then I added the N35 Deaver mini pack. Now I will go up to slot 3 or 4. I don’t want to go a full 2” without new front 1/2 shafts.

 

damn 90 out photos smh.

How much lift in the rear did you get from the Deaver mini pack?

1"-1.25" total rear lift.

 

1/2 tank of fuel before 37.5" driver side 37.25" passenger side. 3/4 tank of fuel after 38.5" driver side 38.25" passenger side. DEF tank was about the same before and after. Rear ride height is affected much more with cargo weight compared to stock leafs.

Did you get the 5100s put on the back?  Do you happen to have a side shot?  I have a black sierra with the 2" factory lift and want to get my nose up.  Thinking about the 6112s and 5100 combo.

So I went with the Zone lift level with control arms and 35s on method wheels on a trail boss and what I'm experiencing now is what I would call an "anxious" or "jittery" suspension. Very bouncy/jittery over bumps and very anxious to spring back. 

I'm assuming the Ranchos are not that great so I've been looking into this 6112/5160 setup. 

I assume everyone with lifted wheels and tires notice significant smoother ride quality with the bilsteins?

I just ordered the 6112’s for my LT 4x4 today. Super excited to install them. I will be removing my leveling blocks and swapping. For the rear I have the Helwig swaybar and the Road Master Active suspension (RAD) the heavy duty version, new shocks for rear are next. The RAD lifts the rear by 1-1/2” by pulling the leaf springs together. Gonna add a 1” block to keep a rake because I haul often. I absolutely love them! Just wanted to share because I see you guys mentioning blocks etc. to lift the rear so often. I don’t think many people know about the RAD kits, but they are amazing. My opinion of course. Better than air bags.

Thank you. Set at full 2.0” lift for the 3.0 diesel. I also added a rear block to maintain about 1.0-1.5” rake. It surprisingly looks level but there’s still a rake and I have some wood and deer corn in the back. I have not noticed any sag yet

What size rear block did you use?

I have not seen an answer for what the physical differences between the two 6112 part numbers. However, I went ahead and ordered the 47-309524 back in March and may some day receive them. I hear some are finally starting to come in from the nation wide backorder. Has anyone received 6112s recently? When did you order them and who did you order from?

 

My overall build plan for my 2020 RST Duramax is to use the 47-309524 set on the middle clip with the Bilstein control arms and trail boss axels up front. Out back 2" block with 5100s. My original GY Fortitude HTs were shot at 42k so just replaced them with General Grabber ATXs 275/70R18(SL). Eventually when everything is installed, I will get measurements and pictures posted.

I really like my rough country 2" leveling struts and rough country v2 rear shocks with 1" blocks on my 2013 sierra. I haven't noticed any drop(although i didnt measure).

I've got a 2019 Sierra now and the stock ride isnt near as nice. I was looking to do the same upgrade, but this thread has me questioning it. Is it really worth the added cost?

      Doors lock and mirrors fold in while driving

      By BIGBOYS · Posted

      I have a 2015 Silverado and sometimes I can not get in to the truck. I use the key to unlock the driver door. Something is locking the truck when I unlock it, last night I left the truck open and this morning it was locked with the mirrors folded in. This happens while driving so it is now a safety issue. I reach down for the folding button and they open, then they close again.  Any advice, thank you,   Ed

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By William Aldrich · Posted

      NewDude, thank you for the suggestions!    I did follow up and the dealer indicates he has an open CX case and is working with DPAC (Dealer Parts Assistance Center).   Per the dealer, GM has had a quality spill and is not providing an update for when a replacement engine will be available.
