❓ Frequently Asked Questions

Will these fit my Cadillac IQ EV?
We are confirming fitment for Cadillac IQ EV SUVs, as they share a similar lift point design. Check back soon for updates.
Can I use these with a floor jack or bottle jack?
Yes. Each puck includes a 1.30" integrated bottle jack port. We recommend the Torin Big Red 10T or a high-lift floor jack like the Daytona 3-ton (ideal for Hummer EVs with 37” tires). Low profile floor jacks work well for non-Hummer trucks.  A heavy-duty scissor jack is easy to store for roadside servicing. 
Are these strong enough for a full vehicle lift on a shop lift?
Absolutely. Each puck is rated at 7 tons, so using four at once on a commercial lift is safe and reliable.
Why are GMX pucks priced higher than Rivian pucks?
GMX is new, and smaller runs mean higher early costs. With Rivian, we now order 10,000 from our machine shop at a time—bringing prices down. As GMX scales, costs will drop too, and we’ll pass those savings on to you.
Do you offer a 4-puck kit with a case?
Yes! Buy 4 and you’ll save $35 plus receive a free custom padded case while supplies last.
