What is The ShockSims® OBD/SS?
The OBD/SS Module is our most popular product. It provides a plug-n-play solution for replacing stock magnetic (FE4 - F55 - Z95) suspension on the latest generation of GM vehicles.
The module plugs into the OBD2 port communicating ONLY with the Suspension Control Module (SCM). The Module then manages the behavior of your vehicle's SCM so no speed limiter or service suspension messages will be present.
Where do I plug in the OBD/SS Module?
Our Classic module with the largest vehicle support plug into the OBD2 port.
Our other modules may require alternate power sources or additional signal taps. Please refer to each product page for install guides.
Will the OBS/SS drain my battery?
No. The OBD/SS turns off 5 seconds after it stops seeing traffic on the CANbus.
Does it have to stay plugged in?
Yes. The OBD/SS must stay plugged in to bypass your magneride.
What if I want to plug in a different device on my OBD2 port?
We offer a OBD2 Port Pass-thru Cable that will allow you to run an additional device.
Does the OBD/SS require a Ride Height Trim procedure?
The OBD/SS does not require a trim procedure! No Scan tool needed.
OBD/SS uses the OE ride height sensors, leave those plugged in and your stock ride height calibration will be read by the OBD/SS. If you are removing the stock ride height sensors because of a lift or lowering kit, we offer ride height simulators.
If I only replace my front struts will my rear struts continue to work?
Yes they will. All previously working components that are still on the vehicle will continue to work.
OBD/SS is intuitive enough to pick up on exactly what is missing, and bypass it.
What if I have Auto Level in the rear?
This applies to 2015 and up Suburban LTZ - Tahoe LTZ - Yukon XL Denali - Yukon Denali with RPO Z95 AND RPO Z85.
If you need/want to keep the Auto Level Functionality, you would use our OBD/SS Module and replace the Rear Shocks with non magnetic AIR Shocks.
With our OBD/SS Installed and Air Shocks in the rear, the Auto level will function as normal.
If your OEM rear magnetic AIR shocks are in good shape and functional, leave them installed on the Truck/SUV. Install our OBD/SS Module and replace the front with your choice of new conventional struts. The rear auto level will function as normal.
If you do NOT need or want to keep the auto level functionality, you would use our OBD/SS Module and replace all four magneride shocks with conventional shocks.
You would then need to bypass the Auto Level air feature by following along to our video linked here -> ALC Bypass Video
Do you plan on towing with your (Tahoe/Suburban) or (Yukon/YukonXL)?
If yes, then retaining the air-ride suspension in the rear would be the best option.
If no, you can replace the rears with non magnetic non air shocks and follow the video in question above to bypass the Auto Level air feature.
What are the Ride Height Simulators For?
If your vehicle is lifted or lowered so that the original ride height sensors are no longer attached then you would need to purchase our Ride Height Simulators along with the OBD/SS Module.
How long does it take to install the OBD/SS Module?
It is a plug and play system taking a few minutes to install. It simply plugs into the OBD2 port.
