MADE IN THE USA

NOT a Chinese made OEM.

This comes with step-by-step installation instructions!

We at DaRossi LLC have been making replacement couplers for years. We pioneered our own special process for creating a better than OEM coupler. We sell to many GM and Ford dealships throughout the US, Europe, and Austailia. Watch out for inferiors such as the power reducing "stand off" style.

What you are purchasing is:

(1) Uprated supercharger coupler

IF REQUESTED (1) OEM replacement oil fill drain screw and gasket

(1) Simple pictoral general step-by-step instructions


Don't reuse the old cracked gasket on the existing plug when refiling with new oil. 

The superchargers come in size:

M45 Mercedes non-clutch type

M45 (such as Toyota Tacoma)

M62 (Bonnevilles)

M90 (Thunderbird SC, Bonnevilles etc.)

M112 (Lightning)

It is commonly found on the Pontiac Grand Prix and Bonneville, Buick Regal and Riviera, Ford Thunderbird, SVT Mustang and Lightning.

The coupler is precision machined from a green oil impregnated polymer material which greatly reduces wear and offers a long life.

The coupler is a common wear/replacement part which is very easy to replace. Often, the coupler holes on a high mileage vehicle start to become elongated which can cause an annoying noise to be heard. The actual unit may vary slightly in design from the one shown.

We accept Paypal and ask about other forms of payment.

All orders to Turkey, Italy, Russia, and a few select other countries must add $16 for Registered Mail shipping.
