You CAN remove the Z45 shocks from your Sierra Denali for FREE! It will NOT change the stock 98mph speed limiter.
But it does show that annoying "Service Suspension" message on your dashboard on startup until you press OK. So you can press OK every time your truck starts (no biggie) OR follow along with this video to bypass the message for FREE!

DISCLAIMER: This method is a little labor intensive and will render your struts as standard struts once the actuator coils are removed. But you don't need those stock shocks anyway!

About RPO Z45 Adaptive Ride Control
2019 thru 2022 GM Trucks use active valve shocks
- GMC Sierra - Denali
- Chevrolet Silverado - High Country
The active suspension actuator coils are integrated in to the shock body.

The Z45 system operates by charging the coil at all times which is why an aftermarket 'bypass kit' would require a LARGE heat sink. Turns out YOU already have everything you need to bypass them.

By removing the actuator coil from the shaft, bolting the assembly together, and mounting them back under the vehicle, the Suspension Control Module (SCM) thinks the entire active shocks/struts are still present.
