No, a RST doesn't sit 3" higher than an LT.  They should be the same ride height.

 

You haven't really told us anything about your truck to help identify the exact package needed, so hopefully this helps.

i have stock 2WD with Gov lock ,2016 LT truck, looking to do some gold prospecting and exploring here in California and AZ , so I travel lots of dirt roads, I'm scraping a lot in the ruts and need a 2-3" lift, but dont want to change my stock wheel tire combo

 

i noticed several new 2020 rst trucks sit much higher than mine and wonder if GM has done a lift on these vs My LT truck?

 

i do like the front camera option, as i can never see where i'm going when i round the top of a hill for decent..

Hello from South Carolina!

I just purchased a Z71 RST, and was looking for what part numbers from the GM Factory 2" Kit I would need.  I have heard many things in forums indicating different things, but the dealership noted that I would require the entire kit for my truck.  While I would be a little skeptical, the service department manager has the same truck as I do, and showed where he had to do the same.  $1600 for the kit and complete install.

Where do we start with this one?

 

The new T1xx trucks (2019+) are completely different from previous generations, starting with the frame and going up.  You're comparing apples to oranges.  If the new RST sits higher than your 2016, then start there.  If you need 2 more inches on top of those 3, get the Trail Boss suspension package I linked above.  Or, just buy a Trail Boss from the start. 

 

Your other option is to go with an aftermarket lift kit for your 2016.

See posts 2 and 6.  Same part number.  GM is only selling it as a kit.

ok, not sure I would want to waste good money overpaying for a new RST or z71,  I figured the T1 chassis are still fairly similar to a k2xx being so close generation wise..  but i see THere are other ways to go about it. not using GM parts.  I just figured they put in a little more engineering the kit than aftermarket but i'm usually wrong.

 

also wondering what would the opinion be on a spacer lift vs a Knuckle lift?

Let me put it this way.  My neighbor bought a 2016 F150 new 5 years ago for $39k.  He just sold it to a dealership earlier this week for $36k.  It was his daily driver.  Losing $3k over 5 years is a he'll of a good deal. 

 

Now for his bad news.  He needs to buy a new vehicle.  Due to the microchip shortage worldwide, I wish him luck with that.

You're entitled to your opinion, and I'm entitled to disagree.  But, keep in mind professional athletes are not chosen for their looks.  They are chosen for their capabilities.  You wanted a truck that could a desired result.  If you think a T1xx serves the function, then get one.  If you're looking for a supermodel, then this truck isn't the right one for you.

Then why come to the T1 forum to impress us with your ignorance?

T1 is a ground up whole new frame compared to K2.  K2 was a minorly tweaked GMT-900 frame.  Nothing is the same between the two frames.  

 

What more "engineering" were you expecting?  The GM 2 inch kit is literally all the parts pulled from the Trail Boss.  The longer shocks, extended CVs, crash compliance brackets, blocks, longer u bolts, etc.  The parts were already "engineered" for the Trail Boss.

I would never own a 2016 LT 2wd, they are fugly, and tuning can't fix fugly.

      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

      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? 🤔
