DSM Saturn Alternator Adapter


This adapter allows a factory DSM alternator tensioner to work with a Saturn alternator in the factory  location (not relocated behind the engine).

When keeping the Saturn alternator in the factory location, the factory tensioner bracket won’t match up unless it is flipped upside down and the tensioner bolt is rearranged. This certainly works, but since it can’t be effectively locked down, the long bolt used to tension it is put under cyclic loading that can cause it to fatigue and shear off over time. This is a simple solution that secures and tensions the alternator like stock, gives the most adjustment range possible, and has a locating tab to put it at the correct orientation.

Includes the stainless steel adaptor and a 12mm hex bolt to attach to the Saturn style alternator. Fits both 1g and 2g 4G63

Please note: As with any Saturn alternator swap, the normal grinding/clearancing will still be necessary at the lower pivot. More info in our Technical Center Article: Tech – DSM Tensioner to Saturn Alternator Adapter
