When you are stuck on the shoulder with a flat, the wrong emergency tire jack turns a 15-minute tire swap into a long afternoon. Between these two used German jack options, one is an aluminum jack for Porsche 944/924 owners and the other is a factory Mercedes tool kit for the 2006-2012 W251 R-Class. They serve different cars, so the decision comes down to which platform you drive and whether you need the complete emergency tire setup or just the jack itself.
Quick Verdict
The Mercedes W251 Emergency Spare Tire Jack Tool Kit is the better buy for most shoppers: it is aimed directly at the 2006-2012 Mercedes R350/R550/R500. The Porsche 944/924 Spare Tire Jack Lift Tool makes sense for 944/924 owners who want a factory-style aluminum jack.

Where the Porsche 944/924 jack wins
Choose the Porsche 944/924 Spare Tire Jack Lift Tool if you are maintaining an early 944 or 924 and prefer a factory-style aluminum jack with an OEM finish. The Germany-made unit was removed from a 1983 944 and is listed for the 1983-1991 fitment, so it feels at home in a period-correct tool collection. Its biggest advantage is simplicity: one aluminum tool, less weight in the trunk, and no bulky storage box to manage.
Where the Mercedes W251 jack kit wins
Buy the Mercedes W251 Emergency Spare Tire Jack Tool Kit if you drive a 2006-2012 Mercedes R350/R550/R500. It is sold as a complete emergency spare tire jack tool kit rather than a single component, and the listed Mercedes part numbers 2514000002 and 2518990061 give you concrete references if you want to match it to the factory original.
Closer look at each emergency tire jack
Porsche 944/924 Spare Tire Jack Lift Tool
The Porsche 944/924 Spare Tire Jack Lift Tool is the lighter, simpler pick for drivers who already own a factory jack handle. This used unit came out of a 1983 944 and keeps an OEM finish, so it suits someone restoring or maintaining an early 944/924 with original-style tools. The limitation is clear from the product title: there is no handle included. You are buying only the jack tool, so you need a compatible Porsche handle or a suitable generic one to actually lift the car. The 3-month manufacturer warranty gives a little peace of mind for a used part, but the no-handle situation makes it less convenient than a complete set.
Mercedes W251 R350 R550 R500 Emergency Spare Tire Jack Tool Kit
The Mercedes W251 Emergency Spare Tire Jack Tool Kit is the more complete and more affordable choice for 2006-2012 Mercedes R-Class owners. It is a used factory kit with Mercedes-Benz part numbers 2514000002 and 2518990061. At $69.00, it undercuts the Porsche jack by $18.67 while delivering a kit rather than a lone part. The limitation is fitment: this is intended for W251 R350/R550/R500 models, not for a broad range of cars. It also comes with the usual used-part caveats, but for someone with the right R-Class, this is the more practical emergency tire setup.
