Gunner99. Did you have any issues installing the kit? Like dash lights because sensors are out of place? Or weird noises driving especially letting off gas at high speed? Etc.?

 

And crush guy I bought the Denali for a lot more than to have magnaride. I also like to not have my front fender drag on a curb when I pull up to a sidewalk. The 1500 front end is lower than I like, so I want to raise it up. But thank you for your concern with my truck choice.

No problems whatsoever. Had a reputable shop install it. As far as I know it was just the block up. Don't think there were hangers or anything. I'll find out tomorow.

Just recently did my 2015 Sierra Denali with the suspension maxx kit. Had my dealer install kit, tires I brought, and aligned the front end for just over $500 parts and labor. Looks awesome and rides

Just for info....   This weekend, had dealer install 2.5" SuspensionMaxx front level and then new KO2 305/55/20. Running 39 psi front and 35 psi rear. Quiet on hwy and no rubbing. Not sure what the

Thanks Gunner. I am interested to see if they had to relocate the sensors at all. The RC kit looks like it uses spacers both under and above the shock/spring with a majority of the height coming from under (thus moving the sensor and the shock absorber equal amounts).

 

I had heard somewhere that leveling the denali can cause the AWD to make some funny noises. But good to know you haven't experienced this at all.

 

How is the ride compared to stock? Do you have any photos of the truck with the kit installed?

 

 

Go big

DangerDick your truck looks awesome. A little taller than Id like to go on mine, but damn it looks good man. What size tires are you running? Would look good with the front windows tinted.

^ pic me what those sensor relocators look like. :)

 

Here's a few photos for you :)

So when a coil spacer is added and the sensor is not moved down, the sensor reads that the arm is higher and alters the suspension profile.

The installer said if it's the 2.5" level only it doesn't require the brackets because it's just raising the entire front . Anything higher needs bracket. I didn't know there were even sensors on the front. This year down at have awd either.

Ride is ok. I felt the difference when I leveled it and felt more with the 24" rims on it.

I'll look at it again when I get it back from the dealer after the tranny replacement .

The way it raises the front adjusts the angles. My lift extends the bottom of the shock, yours doesn't.

Truck is looking mean Dangerdick. Seems like you know quite a bit about these sensors, Im still struggling a bit. Is the sensor location relative to the shock the only important relationship to maintain? or is the sensor location above the road below also a critical dimension?

 

 

"Sensor w/ factory bracket (no adjustment up front because control arm angle doesn't change with lift)"

The way it raises the front adjusts the angles. My lift extends the bottom of the shock, yours doesn't.

 

 

Maybe I'm slow but I dont quite understand what youre saying in these two comments.

 

The red text was from you post with photos. So are you saying the way your lift installed (under the shock), you did not need to relocate the front sensors?

 

The other comment in the quote box, Gunner said his shop said he did not need to relocate because it lifted entire front. From looking at the RC kit it has a spacer under the shock and a smaller spacer above the spring, so im not sure what was meant by lifting the entire front. Then you say the way it raises front shocks adjusts angles, your lift extends bottom his doesnt. So are you saying he should have had relocation brackets for the sensor or not?

 

Again sorry if everyone else understood this, maybe Im just slow.

What happened to the Tranny already? Truck cant be that old.

Front sensors are not relocated, no. I drew these images up to hopefully explain it better.

 

Here's the stock setup, which remains the same with my lift. In both situations, the upper control arm does not have it's angle changed, as with a full lift the spindles are changed to longer ones and the shocks are extended down.

Now when you add a spacer above the coil, you cause it to reach lower, pushing the lower control arm down and bringing the front with it, as they're connecte with balljoints at the spindle. This lowering of the upper control arm negatively adjusts the magneride sensor.

 

Note the blue spacer added into the mix and the altered angles. Now the shocks are being energized, as the truck thinks its bottoming out, all the time.

A correct install would lower the sensor location or lengthen the linkage rod to compensate for the altered geometry.

Thank you.

 

This is exactly what I have been looking for. I have not been able to get under my tuck to chase down how the system really works, due to weather and then traveling for work. These sketches do a perfect job explaining how the magnetic ride sensors work on the front suspension. Thanks for taking the time to draw them up.

 

It looks like Gunners 2.5" RC level kit has 2" blocks for the rear which replace the stock 1" blocks. Looking at how your lift is installed, it looks like Gunners lift would still need 1" drop down brackets fabbed for the sensors.

 

RC makes a 2" level kit that just has the spacer for under the shock in the front (no spacer above the spring and no rear lift), thus not changing the UCA angle. This kit should work.

Good evening, I am also wondering, the truck shop and dealer, GM stated that there is not a kit yet that would keep the computer from going haywire and constantly trying to readjust the ride. I pick mine up tomorrow, ordered 6.2 with the longer bed. If there is a kit that keeps the sensors from going crazy, I would be interested in picking up. Thanks

And therein lies the problem.

Isn't anything that accomplishes this for a 2.5" level kit.

I'm not 100% sure tbh.. If you lengthen the overall distance between the shock tower and the lower control arm, whether it's above the spring or below, and don't lengthen the arm on the spindle to match, you will alter the geometry and therefore the angle readings from the sensor.

 

I would be leery about doing anything without lengthened spindles or sensor linkage.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.

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

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

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

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

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

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
