changing mrc shocks with gas shocks

[wot_denali]

since i bought my denali till now i can see that gm could not solve the vibration issues,i drove 2 base yukons with 18" rims and non mrc shocks and the ride was perfect,so i was thinking if i can replace the mrc shocks to a normal shocks,do i need any modifications?

Maybe Norcal would know! Needs bypass wiring so it doesen't show on the gauge cluster. Somebodies got to make them!

What is so frustrating about this is that GM knows about the vibrations and frankly crappy ride at low to medium speed issues, and all it would take is new software calibration for the MRCs to (possible) cure the above.

WTH is taking them so long?

I disconnected the front mag shocks connector,for more than 4 months,the car is like yacht,

One would think with all the companies that have received license to use this tech...gmc...Ferrari...bently etc etc etc...

That someone would have a controller going out there...or at least would be able to point a direction to a tuner who could then through together a new algorithm or map for us land yachts...

I just disconnected mine, Ride is a little better but still sucks. It does come up
saying service suspension soon. 2015 Denali Xl, lowered 2/3 with spindles.

After running without the mrc shocks plug in, it would only
run 85 mph. plugged them back in and as fast as you wanted to go.
I bought new Suburban LS std. shocks, but need to get the right
ohm by-pass for the computer. Tried some bypass for a autoride system
up to 2014 but didn't work. Still said on the dash "Service Suspension"

Arnott Suspension has them for up to 2014. They said it might be a couple
of years before they have something that will work.

I would think Tony (Norcal) would have Bypass fix for replacing the MRC shocks

Ordered some 2 ohm 25 watt Resistors, will let you know if they work! The hard
Ride is driving me nuts.

Truck will only run 85 MPH. Something to do with (Service Suspension)

the new trucks are way different then the older ones. I did a mod on mine no issues. Shoot me a pm

I'm on the east coast. Do you have anyone over here doing work. I'm looking to go to a softer shock on the denali, but would like to bypass the service ride light like others have noted

It's interesting. My Essie rides like a Mack truck with the MR shocks. My LS Suburban rides like a dream.

What size tires and wheels are you running I really love the way it looks I want my suburban Lt to look like that and how does it ride and what kind of wheels are those

Bump. Did anyone find a way to delete the mrc shocks with out throwing a code?

I recently drove a 2017 Tahoe LT with the standard suspension and 20" wheels / Continental tires. The ride was fantastic.

My 2015 Suburban LTZ with the Magnetic Ride Suspension and the same 20" wheels / Conti tires rides embarrassingly bad. It's both stiff and floaty at the same time....pounding harshly over bumps while offering poor damping control. The resulting vibrations felt through the steering and structure make it feel as if you're driving a vehicle at least a couple generations older.

I have not driven a newer vehicle with MRC so do not know if this is resolved, but it's hard to imagine that GM would still have this suspension calibration for MRC "premium" vehicles when the standard suspension setup is so much better.

Can anyone help identify part number changes that will help remedy the ~2015 MRC ride? Are there new strut p/n's? MRC ECU update? The platform hasn't changed, so I'm hopeful there must be some option available.

The easiest way to get the latest updated mrc shocks is to visit dealer and shoot a pic from underneeth the car,those shocks part number is very clear.i had installed bilstien 4600 and they were fine but I noticed I should change the coils becuase the gmc coils is not that strength as the normal gas shocks coils.

Wait. What? That was confusing
