Simply brilliant: Rennstands

If you have ever done repair or maintenance work under a vehicle, you’ve run into this problem: You need to jack up the vehicle at the appropriate spot on its chassis or axles—but, quite frequently, that same spot is the best or even the only place to subsequently support the vehicle safely on jack stands. 

On a vehicle with solid axles, such as my FJ40, this isn’t much of an issue as there is generally enough leeway to jack in one spot under the axle tube and place a jack stand adjacent to it. But on trucks with independent suspension it’s different, and if working on a unibody sedan there are often very specific spots under the pinch weld that are the only recommended spots to put either a jack or a jack stand.

Problem solved, thanks to Richard Bogert of Bogert Engineering, the same people who make the excellent Safe Jack systems. The Rennstand allows you to jack up your vehicle at the correct point and then secure it in the same spot on a three-ton stand, all in one operation.

Operation is simple. Position the Rennstand’s crossbeam on your floor jack’s pad (it will also work with a bottle jack with an adapter) and insert the appropriate cradle for your vehicle, whether a model-specific pinch-weld bracket, a flat plate, or a dished cradle. Jack up the vehicle at the appropriate spot.

Insert the Rennstand’s adjustable legs into the crossbeam’s sockets and insert the locking pins, then pull the locking pins on the lower section ot the legs, adjust them to length, and re-insert the pins. Lower the jack and you’re finished.

The crossbeam adds just under two inches to the lowest height of your floor jack, which could present issues with some sedans or sports cars if you don’t have a low-profile jack. The Rennstand is also wider than many “normal” jack stands, which I suppose might be an issue in certain situations, but not one I’ve run into. The upside of that width is that it is reassuringly stable. The three-ton working load limit (WLL) means that a pair of Rennstands will easily support the front end of a very heavy vehicle indeed (They’ve been tested to 150 percent of that according to ASME standards). The lowest setting on its legs is 11.5 inches, the tallest is 16.5. Bogert plans to introduce taller models for lifted vehicles.

Using the Rennstands on our Tacoma was eye-opening, as I’d always struggled to fit both a floor jack and standard jack stands under suitable sections of the front chassis. Not any more. In fact it made the job easier even on the FJ40. In the past I had to place the jack fairly far inboard on the axle in order to leave room for the stand. This made jacking more difficult since I was lifting more of the vehicle, and undoubtedly put more stress on the axle (not that Land Cruiser axle tubes are exactly weak). 

Of course, it should be obvious that the Rennstands can be employed as standard jack stands as well.

I remember testing Richard’s early products, especially the original Safe Jack for Hi-Lift jacks, and being impressed with his imagination and ability to engineer seemingly simple solutions to problems no one seemed to be able to solve before. The Rennstand (which is patented), is yet another great idea. 

You can find Rennstands here. Note that production is currently running about two weeks behind demand. If you order you’ll be placed in the queue and the stands will be shipped as soon as they’re made.
