The R50JPT model fits most "Exx" and the earlier BMW "Fxx" chassis. Consult the application chart in the photo gallery to determine which jack pad tool fits your vehicle. The base for the R50 tools is 68mm in diameter by 11mm thick. The R50JPT uses Silicone plugs to provide a friction fit in the jack point pockets. When the tools are suspended from the jack points it is very easy to align a floor jack with the jack point. The Silicone plugs are pressed into holes in the block and expanded with a small plastic screw.
This tool must be used with a floor jack which has at least a 3" diameter saddle.
