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 GM variant M62, M90, and M112 blowers. 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.

To complete the job, you will need something to suck the old oil out of your snout, we sell a Supercharger Coupler Swap Kit that will make that pretty easy.. You would also need new supercharger oil. (Most blowers will take 2)

Supercharger Oil: This will allow you to add bottle(s) of oil with your new coupler. Most superchargers will take 1.5 to 2 bottles of oil. To add it with your coupler you will need to type the quantity of bottles you want into the QTY box and then click add to cart unless you also want the swap kit which is listed below.

Coupler Swap Kit: If selected this will include a 60cc syringe/tube, and RTV. This is an easy way to suck out the old oil so you don't have to pull the snout off and have the old oil drain down the the engine.(It will smell horrible for days) The small tube of silicone is used to reseal the snout to housing connection. To add it with your coupler you will need to type 1 into the QTY box and then click the Add to Cart button.

You will need to select both options to receive everything needed to make this job as easy as possible.

Coupler installation

Be prepared for an extremely tight fit of the coupler on the drive pins. You won't be able to install it by hand, so be prepared to use a dead blow/compothane hammer to first install it on the pins in the nose cone. Then when reinstalling the nose cone, line up the 3 remaining holes in the coupler with the blower drive pins and push the nose on as far as possible by hand first. Then use a few of the mounting bolts to evenly pull the nose up against the housing, this while wiggling and pushing the cone on by hand. There won't be enough room to swing a dead blow once the coupler is started on the blower drive pins.
