GM Parts Club
The suspension system on the 2022-2026 Hummer EV is not complicated, but it is easy to spend money in the wrong place on it. This is the version we give people at the counter.
What You Will Notice First
- A clunk over expansion joints that you feel in the floor more than you hear
- The body keeps moving after you cross a dip instead of settling once
- A ride height that sits lower on one corner
- Uneven or feathered tire wear on the inside or outside shoulder
None of these are emergencies on day one. All of them get more expensive if you sit on them.
The Parts Involved
- Shocks.
- Struts.
- Control arms.
- Ball joints.
- Sway bar links.
- Coil springs.
- Leaf springs.
- Strut mounts.
- Air ride compressors.
Why the Factory Part Matters Here
- GM valving is tuned to the specific spring rate and curb weight of your trim, and a generic replacement changes the whole balance.
- Vehicles with adaptive or air suspension talk to the module, and non-OEM parts often will not report correctly.
- Ball joint and control arm geometry sets your alignment range, and an out-of-spec part can make a correct alignment impossible.
Service Interval
Shocks and struts are wear items. Plan on inspection at 50,000 miles and replacement somewhere between 60,000 and 100,000 depending on road quality and load.
Ordering Notes
Trim and package content matters enormously here. Off-road packages, air ride and adaptive or magnetic damping all use different parts than the base vehicle wearing the same model name. On the Hummer EV specifically, trim and package content is the thing that trips people up.
We are a factory GM dealer, not a reseller, so what you order is the same part the service drive installs. Browse our GMC OEM parts catalog or search for shocks.
