General question to those with with more knowledge than myself.  Currently considering ordering a new 2023 Sierra 1500. Its been more than a decade since my last new truck purchase. Thinking of going with a 3.0 Duramax.  However a video surfaced on youtube in the last few days claiming to show a new 2023 sierra with polymer leaf springs.  Of course not everything one see's on the net is true.  Does anyone have first hand knowledge of this? Thanks

Hmm.  Well that spring is new.  It is real too.  Came out on refresh 22s actually.  Looks like crew cab short box 4x4 but no idea if its with a specific engine or not.

 

2019-2023, Silverado Trim with 5.3L V8 (L84) Engine, LT Trim, 2WD, Crew Cab, Short Bed with 3.0L Turbo Diesel Engine and Z85 Suspension have a carbon composite lower spring and has been in use since these T1 trucks came out in 2019.  Gives them a 24lbs weight reduction in the rear (12lbs per spring).  They are a 3 leaf setup, not a mono spring, so yea, this mono spring is new.

Does anyone know if the 2023 1500s with Max Trailering have one or more composite springs?

Crazy setup they went with.  I've seen the catalog drawing of it, interesting to see a live one.

 

As for lifting, this is definitely where the GM Trail Boss steel spring kits would have to come in play.  On that 2 inch lift they sell its required to swap composites for steels to install the lift.

 

It will be interesting to see what the aftermarket can produce for lifting and re-using the composite mono leaf setup.

There is not a lot of information on the new mono leaf spring, I have a friend that works at 4Wheel Parts and he said the aftermarket lifts are coming and will be out soon. I cant wait, I have a '22 Elevation and want to lift the rear 2'.

I finally got a look at a 2023 Silverado 1500 with max trailering (crew cab, short box, 4x4,6.2).  The rear springs are three leaves, not just one, and they look like steel.

Yeah, that's just regular leaf springs. GM really turned me off by not advertising the new polymer leafs at all and just dropping them in the trucks. Seems to be Chev LT models and GMC Elevations without max tow but with x31 or z71 that are getting them.

My 2023 SLT X31 has them. Drives me crazy...my fault for not noticing until after my purchase. Rides fine but I haven't had any towing experience with it yet...we'll see. The towing capacity is still pretty good so I guess they got it figured out.

Bumping an old thread. How can i find out if my truck has the mono leaf rear suspension or not? I have a 2023 GMC Sierra Elevation Crew Cab 2WD truck with the 2.7T motor. Sorry I'm new at this. Thanks.

New to the forum. I purchase a 22 Sierra that also had these springs, when exiting my drive way I get this loud cracking/snapping noise from the passenger side. Can anyone explain this? Trucks had multiple visits to the dealership, torqued U bolts, replace leaf spring inserts, no fix.

      So if you do nothing and they act on their threats like death to America or Israel. And possibly a nuclear war. Whoever survives wonders why didn’t they listen? Or we do something like every President has said they can’t get a nuclear weapon. We’re at the 10 yard line and it happens the time is now or never. I think I’m ok with paying a little more for gas for awhile. It’s a shame that we now live in a world that’s so polarized.

      4-5-6 fails due to design.  Not enough clutches and not enough piston to clutch surface area.  Also the backing plate can bow.     I'd say converter is two part.  The design of converter chosen, and factory tuning of it aka slipping it in D (also L6) for AFM purposes, as well as locking it up in 2nd gear, sometimes 1st, also it will partially lock up at light loads.  All because CAFE/fuel economy requirements.  A billet converter on the stock tune might hold up better, but would still be subject to the stock tuning and how its designed to lock or partially lock.     The most baffling part to me, is the 2007-2013 6L80s didn't have the failure rate the 2014-2018 ones do.  I've been where I work for almost 17 years now, and I recall maybe 3 or 4 of the 07-13 transmissions getting pulled for something.  14-18 on the other hand, it was at a minimum one a month being opened up.    If I had to guess, I'd say the tuning for the gen 5 engines/6L80 setup and its fuel economy goals had a good bit to do with it.  Also, it was bankruptcy time during these years, so I'm thinking some cost cutting was done for the launch of the K2XX trucks.  See also now the 10 speed valve body issues (more cost cutting).  They blow out some mesh screen in the spacer plate, undersized check ball, and the feed limit valve was aluminum and wears out prematurely.         I don't think it was the HP jump from the gen 4 to gen 5?  The 6.2 in the 07-13 trucks was good for 380-400hp during its life/states of tune, and the 5.3 did 310-320hp.

      All this might be worth it had we actually recovered enriched uranium, a WMD, or an actual nuclear deal with oversight. This is a flub of epic proportion, and they all know it.   $5.10 at a station reporting $4.99 last week. Here we go....

      I don't think it's a wild guess Stan I think you hit the target on that reply.
