Should have clarified a bit. I will replace front and rear shocks, that's the numbers I listed if they are the correct ones.

Installed 1500’s in the rear today. Stock height. What. A. Difference!  I wasn’t sure what to expect but WOW!  It rides so much better now, I want to have the fronts done!  The back doesn’t hop around

Hard to tell if it's more shock or more tire since you installed them at the same time.

Install done, for sure an improvement.  Settles a bunch of the bunny hop tendencies and makes potholes more bearable.  Feels more planted on corners for sure.  The ultimate test for me is the highway

Rear AT4/Trail Boss - B8 5100 Series 0-1″ Lift Rear (24-309516)

 

Front AT4/Trail Boss - B8 5100 Series 0-1.1″ Ride Height Adj Front (24-309509)

 

This is what you need if you want t8 change the rancho's in a AT4 or Trail Boss.

Our new RST Duramax finally arrived! I had dealer install the 5100's with the fronts set at at 2", and now the truck looks level front to rear. Front's are # 24-293297 and rear's are # 24-293471. The ride with the Bilstein's is excellent. Added Toyo AT3's (definitely more aggressive looking than the AT2's on our old truck, but much quieter). Side steps are GM's 4" round. Ordered a Leer canopy at the same time as the truck but told still weeks away with production delays. Have various trailers for business and personal use so we are having the Firestone Ride Rite airbags installed at same time as the canopy. This will help keep truck level when the heavier trailers connected and/or truck bed full of gear.

Hi there!

 

I've always run big tall tires but with this truck decided to initially start with LT275/65R18.

For those looking to do this upgrade, here's my review of them.

 

2019 Silverado HC, 6.2L

 

My biggest complaint with the stock suspension was the "kick" of the back end on certain sharp bumps on roadways.  Often, it would make the the truck feel unsettled, as if it kicked sideways a bit, then had to recover to straighten out. I didn't mind any type of floating ride, but that kick wasn't good.

 

Had the Bilsteins put on front and back by a GM dealer (plus a 1 inch block in the back)... think they charged me around $500 for the labor.  Have the front shocks on highest lift setting.  I didn't measure it before, but it raised it quite a bit.  Upon first driving it, it is just a tad firmer than the stock shocks, BUT... because it got rid of 90% of that kick out, bumps actually do feel better, less harsh, and more controllable. It's hard to explain, but a definite improvement over stock.  I've probably put 3-4K miles on it now, and every time I drive it, I'm more impressed with the Bilsteins.  You may not notice a night and day difference, but IMO the noticeable change in ride and how it handles bumps is well worth it.  Going to try some Ridge Grapplers and wheels now to see if I can make a larger than stock size fit.

I hooked up our little fully loaded dump trailer yesterday and with the Bilstein 5100's the ride over bumps was excellent. Zero back end sway or bounce as the shocks are quick to settle the truck down.

 

Only thing of note is the rear springs of this truck are quick to sag even with the tongue weight of the trailer empty. The airbags will definitely help.

Ok, here we go guys and gals

 

I'm been a 2500 guy for 30 years and have always ran stock Bilstein's on my trucks. This is the first 1500 I've had in an extremely long time and as such have a few questions.  Oh, it's a 2020 1500 RST CC Z71 with the 5.3 standard box.  I love the truck especially the ride, quite the difference between the 15's and 25's in ride

 

Anyways, first off the Rancho's sux.  I already have 20k on the truck and I'm looking for shocks.  I'm looking at the 5100's as that is what I've always ran on my 2500's.  I don't care about it being lifted or leveled, ok, maybe a little on level.  What I care about is hauling and towing as after all it's a truck.  I'm thinking of going with the rears set at zero and the fronts maybe an inch, but not much more.  That way it looks a little more level.  But my main concern is the rears as I'm almost always hauling something in the bed or towing.  I tow a 7 x 16 enclosed snowmobile trailer, 2 place pwc trailer, 2 place snowmobile trailer and dump trailer.  Depending on the what I'm towing or hauling the back sags, not what I'm use to with having 2500's.  I'm thinking of getting a set of air bags also.  But the first order of business is the shocks.  Would 5100's  the Bilstein B6 24-293471 be best for the rears and the Bilstein B8 5100 24-293297 for the fronts?  Does anyone think the rears should go up a inch and maybe the fronts 2?  Also, what airbags works best for towing and hauling.

 

Thanks in advance for the help

 

Oh, I plan on running the stock tire size once the factory ones wear out, if that makes a difference.

If you’re running the stock size tires I wouldn’t level it at all. Run some Bilstein 4600’s and call it good.

Hi rv245.

 

I had the Firestone Ride Rite airbags installed last week. What a difference when towing the loaded little dump trailer or the boat...no more sag. Haven't hooked up the travel trailer yet but the tongue weight is close to the loaded dump trailer. With the Bilsteins and airbags the ride quality is great. 

 

Now if only that back ordered Leer canopy would arrive!!

I swapped out the stock rear rancho shocks on my '21 LTZ for the 5100's  about 1k miles ago and couldn't be happier.   It's my first ever pickup truck after many years of minivan or compact car driving and the rear end hop over road irregularities was quite disappointing and a bit unnerving.   Thanks for all the info and advice in this thread for pushing me towards the Bilsteins.

 

I did  the rear shocks myself in the driveway, but the fronts will need to be done by a shop.  Fronts appear to be out of stock everywhere I have looked, so it may be quite a while before they can get done.  

 

Have any of you left the fronts stock long term and just switched out the rears?

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔
