Plug‑and‑Play Adaptive Ride Control Bypass for 2019–2025 GM 1500 Trucks

The OBD/SS ARC (2019–2022.5) or ARC‑R (2022.5‑2025) is an easy module for your Sierra Denali or Silverado High Country that lets you remove the factory Z45 Adaptive Ride Control shocks and struts without any dash warnings. Just unplug the four ARC shocks and connect or plug in the module, and no “Service Suspension System” message will appear. The 2019–2022.5 ARC model installs under the dash behind the OBD‑II port by the driver’s feet, while the ARC‑R for 2022.5+ installs inline with an 8‑pin connector under the passenger seat.

The OBD/SS ARC and ARC-R is only for Gas equipped 1500 trucks.

For Duramax powered 1500 trucks you will need use our ARC-MAX to bypass the shocks.

In this example the 9 in the 5th position would mean the ARC is required. The ARC-R would not work.
