Precision-Built for GM EV Trucks & SUVs
Five powerful rare-earth magnets lock each GMX puck onto the vehicle's designated lifting point for fast, precise alignment before the jack ever touches it.

No balancing the puck. No guessing at alignment. Just a secure connection where the vehicle was designed to be lifted.
With more than 25,000 JackPucks products in service, our magnetic lifting systems are now used by EV owners, dealerships, tire shops and repair facilities across the country.

Frequently Asked Questions
Do you have a scissor jack recommendation that works for roadside servicing, especially with a flat tire?
Our customers use them! A flat tire requires a low‑profile jack (a bottle jack may not fit) that can slide under the vehicle and work properly with our jack pucks. We recommend the 3T (6600 lb) Scissor Jack Kit from Amazon, which has proven effective on heavy GM EV trucks, Hummers, and the Cadillac IQ. In the photos below, Hummer owner Peter O. shows this setup lifting his vehicle easily and performing flawlessly. We do not manufacture these, so we do not know the long term reliability, but this is what many of our customers use.

Can I use these with a floor jack or bottle jack?
GMX pucks are compatible with many floor and bottle jacks, but jack-saddle dimensions and vehicle clearance vary by model. We recommend the Big Red 10‑Ton Bottle Jack from Amazon; the 1.30″ port is designed for that fit. For best clearance, set the vehicle to its highest suspension setting.
For heavier platforms like the Hummer EV, GM recommends enabling Extract and Service Mode. has been successfully used on Hummer EVs with 37" tires using the Daytona 3-Ton High-Lift Floor Jack. For other GM trucks, a low‑profile floor jack works well.
If you’re using a bottle jack, your puck needs a receiving port that matches the jack’s top‑hat diameter. They’re all different. We designed ours around the Torin Big Red 10T Bottle Jack available on Amazon. Big Red 10T Amazon Seen below.
