About this item

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 Eaton 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. Click here to hear Rotor Rattle 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, which can be found here. You would also need new supercharger oil, which we sell here. (Most blowers will take 2) Fits: Land Rover Jaguar 5.0L, 1990 to 2008 GM and Ford Eaton M90, M62, M112 Superchargers, Nissan Frontier / Xterra M62 Superchargers, Toyota Gen 2 TRD Tacoma supercharger. Some of these superchargers factory original coupler has a spring in it. That is a failure point that eats up the plastic coupler. This is a solid coupler that replaces it. This will fix and eliminate the rattling sound from your supercharger.

Ordered to replace the "spring coupler" inside my M62 eaton Supercharger on my 2001 Nissan Frontier - It fit absolutely great. Took all the slop out of it.

Maybe it’s supposed to be like that, but the only way I could get it on is to warm it.

Good product but didn't solve my problem, my problem was something else on my super charger.
