I have been dealing with, researching and agonizing over the Magneride suspension on my 2015 Tahoe LTZ (with max towing package) since purchase date in April 2018. My Tahoe, as with many others I have read about here on the forum, rides extremely rough in the rear, so much so that adults refuse to sit in the 3rd row.
This is the family hauler and daily driver, but I live in Maine and I enjoy getting off the beaten path. My original goal was to lift the truck 4", but research showed that was a challenge, and an expensive one at that. In the end, BDS Suspension is the ONLY company I came across that provides the 4" lift; however, other posts have highlighted the "CHALLENGES" with installing the 4" BDS kit. All in all, more $ spent on getting just a few extra inches and NOT much tire size increase. PLUS, the BDS kit would maintain the factory shocks unless you spend more $ on purchase the front Fox 2.5 reservoir coilovers. Great, but overkill for my setup and probably most rides in general.
SO - where was I left. Leveling the Tahoe. SuspensionMaxx 2.5 Adjustable front kit w/MRC delete, right? 1" coil spacer in back also available with the MRC delete bracket. However, I'm still left with my stock shocks and HORRIBLE rear ride, just up in the air more. Here comes our saving grace, the man with the magic, Max @Xineering.com. Max has developed the GM Shock Simulator, or "Magneride delete" circuitry that literally tells the onboard computer that the Magneride (and AirRide if applicable) is functioning properly. This circuitry allows the driver to install ANY TAHOE COMPATIBLE REAR AND FRONT SHOCK/STRUT/COIL SETUP THEY CHOOSE. In other words, this product gives LTZ and magneride owners the opportunity to convert to a passive suspension system.
Currently, my circuits are shipped and on their way from Xineering's headquarters in Orlando. Once the MRC delete is in place, I am adding the Bilstein B8 5100 rear shocks, 1" rear coil spacer, z71 OEM off-road rear coil spring, and front Fox 2.0 IFP coilovers at 2" ride height. Once I see where the Tahoe sits, new tires are going on. I'm still debating on wheels, I would like to keep my OEM wheels, but the desire for a larger tire and no rubbing may demand new wheels. Also, I am currently sitting on 20" and I think an 18" wheel would provide a better ride as well as improved off road performance.
I will be creating a new thread on my entire MRC delete project once it is underway. Please watch this thread and I will make sure to add a link to my project thread.
GOOD LUCK TO ALL ON THEIR MRC DELETE AND IMPROVING THE RIDE QUALITY OF YOUR TAHOES!!!
