This stand has been specifically designed to accommodate D-Series Engines. The D-series engine actually sits tilting forward so this stand also has been designed to that spec to allow direct bolt up installation or removal. Another key purpose of the stand is that you can mount your flywheel, clutch, and transmission while mounted on the stand. This gives you a completely mobile swap to maneuver around. You can also complete simple tasks such as accessory swaps or installations, cleaning, even assembling your top end if necessary while mounted on the stand. Storing and transporting, even shipping with our engine stands also works great.
