Don't be tricked into replacing your entire blower when you could possibly just need to replace the supercharger coupler itself. A worn coupler will cause a rattling noise at idle that goes away when you rev the engine. This supercharger coupler will fit the entire line of blowers from 1990 to present. We have over engineered our coupler to provide years of trouble free use on cars with smaller than stock pulleys.

Below is a link to a video of a rattle that is NOT caused by the coupler. The rattle in the link is due to rotor rattle which happens when the rotor pack is bad.

Additional components needed to complete the job:

Supercharger Oil: This will allow you to add new oil with your coupler. If you select the GM Supercharger Oil, you will need 2 bottles to fill your supercharger.

Also fits 3.0 Jaguar/Land Rover & 2017 + 5.0 Jaguar/Land Rover
